Voice over Packet (VoP): Next Generation Networks (NGN) Accounting Management Generic Requirements

Issue 6, January 2010

Issue 6 of GR-3058-CORE, Voice over Packet (VoP): Next Generation Networks (NGN) Accounting Management Generic Requirements, replaces Issue 5, and is a module of FR-AMA-1 and FR-NGN-01.

Competition for telecommunications services remains high. Presently, the technological base for telecommunications is moving away from traditional Time Division Multiplexing (TDM) switching systems and toward alternative technologies such as data networks based on Internet Protocol (IP). The newer networks have become technically competitive, cost-effective alternatives to the existing circuit-switching-based solutions.

While IP and voice over packet technologies have greatly matured, both new and traditional telecommunications service providers are finding that the transformation to a broadband Next Generation Network (NGN) has proven to be somewhat more time consuming and difficult than initially envisioned. One factor that has hindered the quick development and deployment of "carrier-grade" IP-based networks is the relative lack of industry-accepted standards and comprehensive generic requirements, particularly with regard to usage measurements. This GR addresses the need for accounting management standards by providing comprehensive generic requirements for generating meaningful usage measurements for NGN elements that must be integrated into the existing network fabric of the PSTN.

GR-3058 describes the functions needed to generate and process call detail recording information for Voice over Internet Protocol (VoIP) and other voice over packet services. These functions include the identification of call events, the creation of Automatic Message Accounting (AMA) records, and the delivery of AMA records to downstream systems. This document describes these functions particularly as they relate to the recording of local, long distance, and network interconnection services, including Number Portability and Toll-Free ("800") Service. GR-3058 also contains information related to the generation and correlation of Protocol Data Units (PDUs) generated for various call scenarios.

Issue 6 includes the following:

  • Improved alignment with standards work being done in 3GPP (third generation Partnership Project), ITU-T (International Telecommunication Union-Telecommunication), IETF (Internet Engineering Task Force), and TM (Telemanagement) Forum IPDR (Internet Protocol Detail Record)
  • A more current description of the functioning of the Session Border Controller
  • A discussion of Event Messaging in relation to Protocol Data Units
  • Quality of Service and Service Level priorities incorporating the values defined for differentiated services (DiffServ) by IETF
  • Changes to population rules for Module 260, IP Packet/Party ID
  • Changes to the population rules for Module 204, Service Indicator, specifically for BAF Table 610 (DiffServ values captured in BAF module).

Suggested Optical Cable Code (SOCC)

Issue 4, May 2010

Telecommunication providers have witnessed an explosion in bandwidth demand by voice and data users. To meet this demand, Local Exchange Carriers (LECs) and long-haul providers beefed up the transmission payload on each fiber by upgrading the electronics at the termination points. This concentration of information heightened an awareness that network reliability and upgradability will become the dominant concern of service providers, especially where protect network routing may not be sufficient to provide acceptable connectivity for the users.

At the center of the optical network is the optical fiber cable. Network upgrades are most efficiently implemented by understanding the limitations of the optical fiber link. Important information is the characterization of the optical fiber, which is one of the fiber attributes identified in this document.

SR-2014 contains a descriptive generic cable identification scheme for optical cables. Communications companies use the code to order interoffice and subscriber feeder cables; and manufacturers use it for internal operations, billing, and inventory control.

This document sets forth a Suggested Optical Cable Code (SOCC) prepared by Telcordia Technologies for optical cables used in long haul, interoffice networks, subscriber loops, and premises wiring. The code offers an algorithm for describing optical cable characteristics that are needed for ordering restoration cables, maintaining plant records, controlling inventory, and utilizing the mechanized ordering systems of users and manufacturers. The code in this document does not offer a complete description of a cable product to its lowest denominators, but provides sufficient information on major optical cable components.

Issue 4 contains all new codes issued since 2000. SR-2014 complements the requirements defined in the latest issues of GR-20, Generic Requirements for Optical Fiber and Optical Fiber Cable, and GR-409, Generic Requirements for Indoor Fiber Optic Cable. GR-20 provides the interoffice, subscriber, and aerial cable requirements. Additional cables from GR-20 that are coded in SR-2014 include:

  • Self-Supporting Aerial Cable
  • Optical Fiber Drop Cable
  • Indoor-Outdoor Optical Fiber Cable
  • All-Dielectric Self-Supporting (ADSS) Fiber Optic Cable
  • Micro-Duct Cable.

GR-409 addresses cables intended for indoor use, and they are also coded in SR-2014.

Emergency Services Border Control Function (BCF) Generic Requirements

Issue 2, February 2010

The National Emergency Number Association (NENA) long term solution for emergency calling, referred to as the i3 Solution, assumes end-to-end Internet Protocol (IP) signaling from the Voice over IP (VoIP) endpoint to an IP-enabled Public Safety Answering Point (PSAP), with callback and caller location information provided to the PSAP with the call. The i3 Solution introduces the concept of the Emergency Services IP Network (ESInet), which is an IP-based inter-network (i.e., network of networks) shared by all agencies that may be involved in providing assistance during an emergency. A local ESInet, which would typically be county-wide, will be interconnected to a neighboring county's ESInet for mutual aid purposes. Because ESInets are IP-based, such interconnections will allow any agency to communicate with any other agency or service on one of the interconnected ESInets.

The National Emergency Number Association (NENA) views an end-to-end architecture consisting of originating networks and Emergency Services IP Networks (ESInet). PSAPs, which use as well as provide services on the ESInet, will also support internal networks. The Border Control Function (BCF) is an important functional element of the i3 Solution architecture because it provides the first line of defense against deliberate attacks on the ESInet. It is expected that PSAPs will also support a BCF between their internal networks and the ESInet. The BCF provides secure entry into the ESInet for emergency calls presented to the ESInet by incorporating firewall and admission control functions, as well as anchoring of session and media, and other security mechanisms to prevent deliberate or malicious attacks on PSAPs or other entities connected to the ESInet. The BCF is in the path of all call signaling and media. As a result, this element must be highly reliable.

This new element is critical to allow secure entry into the ESInet for emergency calls presented to the ESInet. This component also provides functions to ensure the smooth processing of emergency calls/sessions, including signaling protocol, repair, translation, and interworking, codec negotiation, support for Qos/priority markings, and support for emergency call transfer.

This document is the only public document that fully describes the functionality, interfaces, and operations requirements associated with an emergency service Border Control Function.

Generic Requirements for Separable Electrical Connectors Used in Telecommunications Hardware

Issue 2, December 2008

GR-1217 contains proposed, generic physical design requirements for separable connector products used in a typical service provider network. The generic requirements defined in this document apply to separable electrical connectors used in typical service providers' electronic telecommunications networks. The scope includes Printed Wiring Board (PWB) connectors, coaxial and cable connectors of various types, and IC sockets. It includes connectors made with noble and non-noble metal contact finishes. However, these requirements do not apply to non-metallic optical connectors used for mating of fiber optics or to connectors intended for AC power applications. The pin and socket connector, widely used by equipment manufacturers to interface PWB assemblies to backplanes in current telecommunications systems, is the most prominent and the most critical application within this scope. Edge-card connectors with plated contact fingers are also included in the PWB classification.

This document expands and enhances the separable electrical connector requirements found in GR-78-CORE. Quality and reliability aspects for separable connectors as components detailed in GR-357-CORE are also included. Where there is a discrepancy between requirements in this document and requirements in these two more general documents, the requirements here take precedence.

GR-1217 meets all quality level standards for electrical connectors, plus:

  • Provides a comprehensive treatment of electrical connector performance for telecommunications hardware and addresses both noble and non-noble plated connectors
  • Includes a flexible qualification methodology, which allows for cutting-edge product innovations to be qualified and used in telecommunications products
  • Emphasizes connector performance via qualification tests, as opposed to preferred metallizations; connector performance metrics were reviewed and modified where appropriate to account for reduced connectors geometrics now typically employed
  • Defines accelerated aging test methods, which can be used to determine reliability of mean time between failures of a particular connector.

Issue 4, October 2009

The digital synchronization network consists of clocks connected by digital facilities. This document provides criteria that apply to these various clocks deployed in telecommunications equipment such as transport Network Elements (NEs), Digital Switches, and Timing Signal Generators (TSGs). Since these clocks can have a critical impact on network performance, GR-1244 may be of significant value to telecommunications equipment manufacturers (including both synchronization-related component and system manufacturers) and telecommunications service providers.

The updates in Issue 4 should significantly assist the reader's understanding of the criteria (and expected clock performance characteristics) in areas such as holdover stability, wander generation, and phase build-out. Specific updates include:

  • The equations for calculating fractional frequency offset and drift were corrected, and additional information on the use of those equations was provided
  • The temperature component of the holdover frequency stability requirement for stratum 3 clocks was changed to align with the corresponding specification in ATIS-0900101
  • Significant explanatory test was added regarding the holdover stability curves provided in Section 5
  • Additional explanatory text was provided regarding the conditions under which the wander generation requirements apply
  • The proposed value of one of the parameters used in defining test cases for testing a clock's phase build-out performance was changed to reflect the long time constants of the filters used in stratum 2 and 3E clocks
  • Additional information was provided regarding the applicability of various criteria to NEs/clocks used in SONET or "synchronous Ethernet" applications.

In addition, minor corrections or clarifications were made in the text in various sections of the document, references to ANSI T1 standards were changed to reflect their reclassification as ATIS standards, and references to the ITU-T documents related to synchronous Ethernet were added to a number of sections.

Generic Requirements for GetData

Issue 6, December 2008

GR-2838 identifies generic requirements for Line Information Database (LIDB), LIDB Administrative System (LIDB AS), and Query Originator (QO) functionality needed to support processing of GetData. GetData provides flexible query and data element definition capabilities that allow LIDB owners to rapidly develop the query and data element definition capabilities needed to support new services.

The GetData query is a service-independent LIDB query (and associated responses) that can be used to request specific data elements from a record in LIDB. To support the GetData query, QOs access the LIDB associated with a service key to obtain data element information for the line record identified by the service key. Also included as part of GetData is a mechanism that allows LIDB owners to define customized LIDB data elements over the LIDB AS-LIDB Interface. Information contained in these customer LIDB elements can then be retrieved by the GetData query.

Issue 6 incorporates the following:

  • Support descriptions, format, and encoding rules for two (2) newly defined standard elements, which are retrievable from LIDB via GetData.

The two (2) new line elements are:

  • The Extended Name (EN) String which can store up to 60 characters of name information associated with a telephone number (TN), thus making available a longer version of the Generic Name String (currently limited to 15 characters)
  • The EN Presentation Indicator specifies whether the name associated with a Telephone Number (TN) is "public" or "private."

The Extended Name String and Extended Name Presentation Indicator may be retrieved for the CLASS Calling Name Delivery feature, where longer names could be supported in signaling and CPE, as well as for various GetData and IP-based applications.

AS/LIDB-AS/LIDB Data Migration Interface Generic Requirements

Issue 4, April 2009

GR-2992 provides the Telcordia view of generic requirements for the Line Information Database Administrative System (AS/LIDB) to AS/LIDB Data Migration Interface. The generic requirements for the interface include primarily the modes of data transfer, a data model, a data dictionary, and the application protocol used by the AS/LIDB. The application protocol is a set of conventions to manage communications between two entities.

Data Migration refers to the actions taken in the case when the end-customers' data and their service providers' data need to be moved from one AS/LIDB to another. The generic requirements in this document apply to an AS/LIDB's assembling, formatting, and transferring data for use by another AS/LIDB. This document includes generic requirements for the predefined AS/LIDB data items, data item aggregates, and protocol procedures for the AS/LIDB-AS/LIDB data migration interface. It also defines procedures for transferring AS/LIDB custom elements used for GetData.

Issue 4 incorporates the following:

  • Support for descriptions, format, and encoding rules for two new line elements (data items), and to add them to the GD aggregate of the logical data model and associated requirements. These elements are retrievable from LIDB via GetData and other wireless and IP-based protocols (e.g., LDAP).

The two new line elements are:

  • Extended Name (EN) String
    • This parameter can store up to 60 characters of name information associated with a Telephone number (TN), thus making available a longer version of the Generic Name String (currently limited to 15 characters).
  • Extended Name Presentation Indicator
    • This indicator indicates whether the name associated with a TN is "public" or "private." An indication of "private" means that name presentation is not allowed for the Calling Name Delivery CLASS feature. An indication of "public" means that name presentation is allowed.

Lightweight Directory Access Protocol (LDAP) Interface Specification for Line Information Database (LIDB)

Issue 4, April 2009

GR-3103 contains the Telcordia view of Lightweight Directory Access Protocol (LDAP) Interface Specification for Line Information Database (LIDB). With its current data on the majority of the working telephone lines, LIDB is a valuable database and resource for a number of diverse industries.

This GR allows an LDAP Client to understand the available/supported capabilities in a LIDB for LDAP requests. Certain LDAP operations, such as DELETE, are not supported by this interface, due to strict administrative requirements and expectations of LIDB.

This LDAP LIDB interface offers Internet Service Providers (ISPs) and Application Service Providers (ASPs) the opportunity to increase their service offerings and their service value to the customer by complementing their offerings with a broader customer profile.

The interface specifications allow for mutual authentication between the Client and the LDAP 'server' at LIDB, using digital certificates and Secure Sockets Layer (SSL) to ensure the necessary confidentiality and privacy of the data. LDAP Clients are expected to set up business agreements with the LIDB owner(s) to define access and administration procedures up front. LIDB is not a free-web-site. The integrity and freshness of its data is important and must be maintained on an ongoing basis (each LIDB contains millions of customers' records). This GR does not include the specifics on each LIDB. The LDAP Client must consult the LIDB owner for the applicable data schema and available data elements.

This document is being reissued to incorporate:

  • LIDB LDAP Support of the Compare Operation
  • The following two (2) newly defined LIDB line data elements:
    • Extended Name (EN)
    • EN Privacy Indicator (ENPR).

The Extended Name field can store up to 60 characters on name information associated with a telephone number (TN), thus making available a longer version of the generic name String, which is currently limited to 15 characters.

The EN Privacy Indicator specifies whether the EN associated with a TN is "public" or "private."

Issue 3 incorporated the descriptions, format and encoding rules for nine (9) newly defined standard elements (Third Party Block, Voice over Internet Protocol Provider ID, Line Technology Type, E-mail Address, E-mail Address-2, E-mail Address-3, E-mail Address-4, E-mail Address-5, and E-mail Address-6).

Emergency Service Zone (ESZ) Routing Database (ERDB) Generic Requirements

Issue 4, October 2008

The National Emergency Number Association (NENA) has been active in the definition of a suite of solutions to enable emergency calls originated by Voice over Internet Protocol (VoIP) users to be routed to the appropriate Public Safety Answering Point (PSAP) for the geographic location from which the call was originated. The Long Term Definition (LTD) Working Group (WG) of NENA has identified high-level requirements and developed an architecture for an end-to-end Internet Protocol (IP) solution. The VoIP Migratory Working Group (VMWG) of NENA has defined a near-term solution that provides for migration toward the long-term view, while making use of the existing conventional E9-1-1 System Service Provider infrastructure. This is referred to as the i2 Solution.

The NENA i2.5 Working Group (WG) has been working to update the i2 Solution to address gaps in the i2 Solution definition, and to reflect industry requests for changes and enhancements to the i2 Solution. In the i2 Solution, it has been assumed that a VoIP Service Provider (VSP) will participate in the handling of emergency call originations. The i2 Solution is expected to support the basic E9-1-1 Service capabilities that are available to wireline and wireless customers today, while minimizing the impact on the E9-1-1 System Service Provider infrastructure and PSAPs.

The i2 Solution defined by the NENA VMWG and updated by the NENA i2.5 WG includes a number of new functional elements to enable the routing of VoIP-originated emergency calls and the delivery of the associated call and location-related information to the PSAP. One critical network element that is involved in selectively routing the VoIP emergency call is the Emergency Service Zone (ESZ) Routing Database (ERDB).

GR-3119 provides generic requirements for an ERDB to support VoIP-originated calls. It includes:

  • Functional requirements for the ERDB
  • Interface requirements for the interfaces supported by the ERDB
  • Data management requirements.

This document provides specifications for a new ERDB element used to support location-based routing of VoIP emergency calls to an appropriate interconnection point with the emergency services infrastructure in the NENA i2 Solution. It may be of use to operators and suppliers of ERDB elements in developing and deploying the ERDB, and also to the Public Safety community.

This new element is a critical component of the NENA i2 Solution for support of VoIP emergency calling. Without this component, VoIP emergency calls are today routed to non-emergency lines, causing delays in service to VoIP callers and impacting Public Safety call answering policies and procedures.

Issue 4 includes:

  • Updates throughout to describe procedures related to the delivery of geo-coded location information on emergency calls where geo-based default routing was applied at the ERDB
  • Updates to reflect the modifications made to the mechanisms for ERDB steering by the NENA i2.5 WG
  • Updates to bring the v8 interface definition into alignment with current definitions provided in the draft update to NENA 08-001
  • Modifications to align the terminology used in this document with the terminology used in the draft update to NENA 08-001.

This GR also includes one or more Issue Lists Reports (ILRs) that detail open or closed technical issues in the main document. The ILR(s) are automatically sent free of charge to the GR-3119 document purchaser.

Universal Emergency Routing Control Point (UERCP) Generic Requirements

Issue 3, June 2009

Issue 3 of GR-3156-CORE, Universal Emergency Routing Control Poiont (UERCP) Generic Requirements, replaces Issue 2, and is a module of FR-E911-1.

The network architectures and capabilities that E9-1-1 Service providers support must satisfy current customer needs as well as support anticipated enhancements to existing E9-1-1 functionality brought about by evolving technologies and changes in the regulatory environment. In addition, it is desirable that the evolution of E9-1-1 architectures service providers are considering also reduce operational costs by consolidating required functionality where possible.

GR-3156-CORE describes the functionality for a network element, the Universal Emergency Routing Control Point (UERCP) that is expected to play a key role in supporting emergency calling as E9-1-1 Service architectures evolve. GR-3156 describes the functions and interfaces that must be supported by a UERCP to allow it to provide critical location-based routing functionality in support of legacy, i2, and i3 Solution E9-1-1 Service architectures. This document also addresses the functions and interfaces that need to be supported by the UERCP to process and respond to requests for routing information received from legacy Selective Routers and i2 Voice over Internet Protocol (VoIP) Positioning Centers (VPCs), as well as Internet Protocol (IP) endpoints, VoIP Service Provider (VSP) routing proxies, Emergency Services Routing Proxies (ESRP), and i3 Public Safety Answering Points (PSAPs).

Issue 3 reflects the following updates:

  • Modifications to align terminology in this GR with draft i2 specification NENA 08-001, Issue 2
  • Updates throughout to describe procedures related to the delivery of geo-coded location information on emergency calls where geo-based default routing was applied at the UERCP
  • Updates to bring the v8 interface definition into alignment with current definitions in draft NENA 08-001, Issue 2
  • Updates to bring the LoST interface definition into alignment with IETF RFC 5222.

Emergency Services Routing Proxy (ESRP) Generic Requirements

Issue 2, November 2008

GR-3157 provides the requirements for the functions and interfaces that need to be supported at the Emergency Services Routing Proxy (ESRP). The ESRP is defined as the routing proxy that is authorized by an appropriate emergency services authority to accept and route emergency calls on their behalf. The generic requirements in this document address the functions that need to be supported by the ESRP. The ESRP is expected to accept incoming emergency session requests, query for routing information, apply any specified policies to determine alternate routing, and use this information to route the emergency session request to the next ESRP or PSAP. In addition, the ESRP will need to support the discovery of the appropriate emergency routing database (i.e., an Emergency Call Routing Function).

In addition to the functional requirements described above, GR-3157 addresses the signaling interfaces and processes that must be supported by the ESRP. The ESRP provides a call routing function and a routing query function and it needs interfaces to support these functions. This document will also provide operations, performance and security guidelines for the ESRP.

Issue 2 includes the following:

  • Addition of a Policy Routing Function (PRF) within the ESRP for determination of alternate routing for emergency calls
  • Removal of the support for an automated root discovery mechanism and interface
  • Alignment with the LoST protocol as defined in IETF RFC 5222
  • Clarification of the role of the ESRP in location determination for calls from legacy networks
  • Proposed clarifications for handling of location information by a routing proxy.

Generic Requirements for a Service Provider Location Information Server (LIS)

Issue 2, June 2009

Issue 2 of GR-3158-CORE, Generic Requirements for a Service Provider Location Information Server (LIS), replaces Issue 1, and is a module of FR-E911-1.

This document details requirements for the functionality and interfaces of a Location Information Server (LIS) providing location capabilities in a service provider network. Specifically, the LIS is responsible for the location determination and location acquisition functions required to support emergency call processing.

Enhanced 9-1-1 (E9-1-1), and emergency calling in general, relies on the use of the location of the emergency caller as the basis for routing the call to the correct Public Safety Answering Point (PSAP). Location is also needed to dispatch the appropriate emergency responders to the right place. The LIS is the element responsible for determining the location of a Voice over Internet Protocol (VoIP) endpoint and subsequently providing the location to the endpoint or other entity so that it can be used to determine routing for an emergency call. The National Emergency Number Association (NENA) interim (i2) and long-term (i3) architectural solutions for VoIP emergency calling include specifications for the functionality of a LIS.

This document addresses location capabilities, including determination of the location and providing location information (known as location acquisition), for a LIS in a service provider network supporting a NENA i2 Solution via a Digital Subscriber Line (DSL) access network. Location determination and acquisition for a LIS in an enterprise network will not be addressed in this document.

This document addresses the location capabilities required for VoIP emergency calling. A VoIP service relies on a combination of network capabilities at different functional layers. A physical connection to the network that supports broadband service is required. Internet Protocol (IP) connectivity is also needed, along with support for voice. The provider for broadband access, internet service, and voice service may or may not be the same entity. Additionally, the manner in which a LIS supports location determination and location acquisition is dependent on the network layer at which it is operating, the type of network at each layer, and may additionally be influenced by the business relationship between providers of each network layer. This document addresses LIS support for location determination and location acquisition for residential VoIP service being provided over a DSL broadband access network.

Issue 2 aligns with the current positions of related standards bodies and industry groups, including the National Emergency Number Association (NENA), the Alliance for Telecommunications Industry Solutions (ATIS) Emergency Services Interconnection Forum (ESIF) committee, and the Internet Engineering Task Force (IETF). Changes in Issue 2 include:

  • Support for an industry standard location-by-reference solution in place of the NENA-specific solution, consistent with planned changes in the definition of the i2 Solution in the next issue of NENA 08-001
  • Alignment with the latest specification for the HTTP-Enabled Location Determination (HELD) protocol, including changes for support for one parameter for civic addresses and additional values for the responseTime parameter
  • Alignment with changes to the NENA v7 interface between the LIS and Validation Database (VDB) for removal of an alternate VDB parameter in the response to the LIS and changes to the v9 interface used by the LIS to discover a VDB

Legacy Public Safety Answering Point (PSAP) Gateway Generic Requirements

Issue 1, June 2009

Issue 1 of GR-3166-CORE, Legacy Public Safety Answering Point (PSAP) Gateway Generic Requirements, is a module of FR-E911-1.

This document provides generic requirements for a Legacy PSAP Gateway to support the delivery of 9-1-1 calls that are routed via Emergency Services IP Networks (ESInets) to legacy PSAPs. The Legacy PSAP Gateway is expected to provide interworking and other functionality necessary for calls routed via i3 ESInets to be delivered to the appropriate legacy PSAP. This document defines the required functions, interfaces, and data that must be supported by the Legacy PSAP Gateway to accept and process emergency call requests routed via the i3 ESInet, to use the information received in incoming signaling to support call and Automatic Location Identification (ALI) data delivery, to process ALI and feature invocation requests initiated by a legacy PSAP, and to interwork the incoming Session Initiation Protocol (SIP) signaling with traditional Multi-Frequency (MF) or Enhanced MF (E-MF) signaling as appropriate for the legacy PSAP to which the emergency call is to be delivered.

This new element is critical to allow continued support for emergency call delivery to legacy PSAPs as the Emergency Service Network and PSAPs evolve to an IP-based architecture. Without this component, there will be no way to deliver emergency call that are routed via ESInets to legacy PSAPs. Delivery of emergency call originations via an ESInet to legacy PSAPs will require some type of gateway system in the call path to interwork the call signaling and support existing PSAP feature functionality.

This document is the only public document that fully describes the functionality, interfaces, and operations requirements associated with a Legacy PSAP Gateway.

Line Information Database (LIDB) Data Screening-Volume 1 (SS7 Interface) and Volume 2 (LDAP Interface)

Issue 5, June 2009

GR-3697-CORE is a module of FR-LIDB-1.

This document contains the Telcordia view of Line Information Database (LIDB) Data Screening generic requirements for LIDB and the LIDB Administrative System (LIDB AS) functionality. The LIDB Data Screening Process permits the denial of access to LIDB data and/or LIDB processing, either completely or partially, from unknown or unauthorized LIDB Service Requesters (LSRs). The LIDB Data Screening process also permits selective return of data based on the capabilities of the Query Originators (QOs) and supports indication of 'ABS Denial' based on the authorization of the LSRs and/or their relationship to the owner of the data.

LIDB service providers need to be aware that retrieval mechanisms for new data elements need to conform to a uniform standard security screening procedure. This document is the only document that describes the LIDB interface and data security procedures.

GR-3697-CORE is divided into 2 volumes. Volume 1 supports the LIDB Data Screening requirements for the Signaling System Number 7 (SS7) interface. Volume 2 proposes the requirements to evolve LIDB to support Data Screening for the Lightweight Directory Access Protocol (LDAP) interface.

Issue 5 includes the following:

  • Two (2) newly defined standard elements, which are retrievalble from LIDB via GetData, and also from other wireless and IP-based protocols (e.g., LDAP Search) via protocol conversion
  • Formats, descriptions, and Element IDs
  • Security requirements to support LDAP Compare Interface.

The two newly defined elements are:

  • Extended Name (EN) String that can store up to 60 characters of name information associated with a Telephone Number (TN), thus making available a longer version of the Generic Name String (currently limited to 15 characters)
  • Extended Name (EN) Privacy Indicator indicates whether the name associated with a Telephone Number (TN) is "public" or "private."

Issue 4:

  • Reserved a specific value in the AO field to represent that the AO information is unknown and another specific value in the AO field to represent that the service provider does not have a NECA code but has another identifier
  • Included the names and corresponding tags for nine (9) newly defined standard elements, which are retrievable from LIDB via GetData, TIA/EIA-41 Search, and LDAP Search queries.

The nine new line elements are:

  • Third Party Bill Block -- Identifies whether or not third party charges can be included on the end user's bill
  • Voice Over Internet Protocol (VoIP) Provider ID -- Identifies the company that is responsible for the end user's VoIP service
  • Line Technology Type -- Identifies the technology associated with the line number (e.g., VoIP, Wireless, etc.)
  • E-mail Address, E-mail Address-2, E-mail Address-3, E-mail Address-4, E-mail Address-5, and E-mail Address-6 -- These are six standalone data elements and each identifies an e-mail address associated with the line number. For example, the E-mail Address data element identifies a primary e-mail address associated with the line number.

Voice over Internet Protocol (VoIP) Positioning Center (VPC) Generic Requirements

Issue 4, September 2008

The National Emergency Number Association (NENA) is in the process of defining solutions that will enable Voice over Internet Protocol (VoIP) customer-originated emergency calls to be routed via a client company Emergency Services Network to the appropriate Public Safety Answering Point (PSAP), based on the location from which the call was originated. The VoIP Migratory Working Group (VMWG) of NENA defined a near-term solution for addressing emergency call originations by VoIP customers, referred to as the i2 Solution. The NENA i2.5 Working Group (WG) has been working to update the i2 Solution to address gaps in the i2 Solution definition, and to reflect industry requests for changes and enhancements to the i2 Solution. As with any E9-1-1 Service solution, the i2 Solution, and any subsequent updates to it, must support the basic E9-1-1 Service capabilities that are available to wireline and wireless customers today. For example, the VoIP network must be able to recognize when a customer has initiated a request for emergency service (i.e., the network must be able to identify an emergency call origination based on information received in incoming signaling). The VoIP network must then determine how to access selective routing functionality to ensure that the call will be routed to the appropriate PSAP for the location from which the call was originated. The VoIP network must provide the PSAP with the necessary callback and customer location information related to the calling party to facilitate the dispatch of the appropriate emergency service personnel to the caller's location.

The VoIP Positioning Center (VPC) is a critical element of the i2 Solution defined by NENA for supporting 9-1-1 call originations from VoIP customers. GR-3118 defines the required functions and interfaces that must be supported by the VPC to facilitate the routing of emergency calls and to ensure the delivery of location information related to VoIP emergency call originations. This document provides generic requirements for the functions and interfaces that must be supported by a VPC as a key element of the NENA i2 Solution.

Issue 4 of GR-3118 includes the following updates:

  • Functional and data element definitions were updated to align with draft NENA 08-001, Issue 2.
  • Sections 5.1.1.2, 5.3.2, and 5.5.24 were updated to remove requirements and update text related to the v3 interface due to plans to deprecate the v3 interface definition in Issue 2 of NENA 08-001 in anticipation of NENA adopting an industry-accepted mechanism to support v3 interface functionality.
  • Sections 5.1.1.5, 5.2.3, 5.2.4, 5.3.3, 5.3.3.1, and 5.3.2.2 were updated to describe the inclusion of geo-coded location information in routing information provided by the ERDB in scenarios where geo-based default routing has been applied.
  • Sections 5.1.2.2 and 5.2.3 were updated to clarify the information returned by the ERDB in a routing response and subsequently stored by the VPC.
  • Various subsections of Section 5.3 were updated to align the message definitions associated with the v2, v8, and v-E2 interfaces with NENA specifications.

Generic Requirements for Fiber Optic Splice Closures

Issue 2, August 2008

GR-771 provides generic technical requirements and characteristics required of fiber optic splice closures. It is Telcordia's view that these requirements be met in order to meet the needs of a Service Provider.

This document provides criteria for analyzing fiber optic splice closures used in a variety of Outside Plant (OSP) environments and applications, including those used in building entrance facilities. Included in GR-771 are proposed functional design criteria, generic mechanical and environmental requirements, desired features, and the performance tests for comparing fiber optic splice closures with the stated requirements. In many cases, the requirements contained in this document are specific to certain closure applications. Organization of these requirements is such that application-specific requirements are identified separately from requirements that are common to all closures. This departure from a UNIVERSAL set of requirements represents the most substantial change to this document. It is intended to permit splice closures designed for specific applications to be available at lower cost than "universal" closures. The performance tests for analyzing fiber optic splice closures are intended to reflect a composite picture of standard installation and operating conditions.

GR-771 is the one document that contains all the general, electrical, mechanical, and environmental requirements for fiber optic slice closure products. This document is referred to by major service providers as the base requirements for these products. Requirements and test methods are contained in this GR document.

Issue 2 of GR-771 features:

  • A broadened scope to cover both fiber optic splice closures and terminals
  • Inclusion of optical monitoring for mechanical and environmental tests
  • New procedures and test methods
  • Updates and changes to mechanical and environmental test procedures and test sequences
  • Application-specific requirements that are identified separately from requirements that are common to all closures. This is intended to permit splice closures designed for specific applications to be available at lower cost than "universal" closures.

Emergency Services Gateway (ESGW) Generic Requirements

Issue 2, December 2007

GR-3129 provides generic requirements for an Emergency Services Gateway (ESGW) to support the routing of VoIP-originated 9-1-1 calls to legacy PSAPs via traditional Emergency Services networks. The document includes:

  • Functional requirements for the ESGW to support trunk/media gateway functionality
  • Functional requirements for the ESGW to support signaling gateway functionality
  • Signaling/Interface requirements
  • Operations, Maintenance, and Performance requirements.

The ESGW is a critical element of the i2 Solution defined by the National Emergency Number Association (NENA) for supporting 9-1-1 call originations from VoIP customers. GR-3129 defines the required functions and interfaces that must be supported by the ESGW to facilitate the routing of emergency calls to the appropriate PSAP via the appropriate Selective Router, based on the caller's location. Without the ESGW component, VoIP emergency calls will continue to be routed to non-emergency lines, as they are today, causing delays in services to VoIP callers and impacting Public Safety call answering policies and procedures.

The information contained in this document will assist developers, manufacturers, and suppliers in providing a NENA i2 Solution-compliant ESGW. It will also assist potential ESGW operators in identifying required functions and in developing implementation plans. Providers of interconnecting elements (e.g., Call Servers/Proxies, Selective Routers) will be able to develop compatible interfaces, and ESGW suppliers and operators will be assisted in designing interoperability testing plans. ESGW providers may see increased revenue by providing accurate routing of VoIP emergency calls. PSAPs will benefit from this document by delivering timely and accurate VoIP emergency calls.

Issue 2 of GR-3129-CORE includes:

  • Modifications to describe procedures related to the replacement of 10-digit North American Numbering Plan (NANP)-formatted Emergency Services Routing Numbers (ESRNs) with Emergency Routing Tuples (ERTs) and Emergency Services Gateway Route Identifiers (ESGWRIs), and support for the delivery of 10 (e.g., Emergency Services Query Key [ESQK] only) versus 20 (i.e., ESQK and callback number) digits of information to the Selective Router with a VoIP customer-originated emergency call
  • Modifications to align the terminology used in this GR with the terminology used in the draft update to NENA 08-001
  • Updates to clarify the role of the VoIP Service Provider (VSP) in obtaining the necessary ESGWRI information from the ESGW provider to support ERT-to-ESGWRI mappings
  • Updates to clarify the relations between the E9-1-1 System Service Provider/SR operator and the ESGW operator to ensure that the ESGW has accurate mappings of ESGWRIs to outgoing trunk groups, and to correctly provision the trunk groups so that the appropriate signaling is delivered to the Selective Router with emergency calls
  • Updates to bring the v4 interface definition into alignment with the current definition provided in the draft update to NENA 08-001.

This document is the only public document that fully describes the functionality, interfaces, and operations requirements associated with an ESGW.

Voice Over Packet (VOP): Next Generation Networks (NGN) Accounting Management Generic Requirements

Issue 5, December 2007

GR-3058 defines the capabilities of a platform capable of producing data about the services used by an end customer or another carrier, and provides the data in a form that enables a carrier's Billing System to determine the charges for this service usage.

This document includes the description of basic functionality needed to generate, process, and output the data describing network usage, and deliver that usage data to downstream systems.

Competition for telecommunications services remains high. Presently, the technological base for telecommunications is moving away from traditional Time Division Multiplexing (TDM) switching systems and toward alternative technologies such as data networks based on Internet Protocol (IP) and Asynchronous Transfer Mode (ATM). The newer networks have become technically competitive, cost-effective alternatives to the existing circuit-switching-based solutions.

While IP/ATM technologies have greatly matured, both new and traditional telecommunications service providers are finding that the transformation to a broadband Next Generation Network (NGN) has proven to be somewhat more time consuming and difficult than initially envisioned. One factor that has hindered the quick development and deployment of "carrier-grade" IP/ATM-based networks is the relative lack of industry-accepted standards and comprehensive generic requirements, particularly with regard to usage measurements. This GR addresses the need for accounting management standards by providing comprehensive generic requirements for generating meaningful usage measurements for NGN elements that must be integrated into the existing network fabric of the PSTN.

Issue 5 of GR-3058-CORE includes the following changes:

  • Refinement of usage event message concepts
  • Expansion of Connect Protocol Data Unit (PDU) encoding to separately show usage data elements for calls originating from VoP-supported lines from incoming calls from the PSTN network
  • Removal of Study/Test Indicator requirements
  • Expansion of Service Provider Type and Service Provider Identification to be provided
  • Inclusion of Quality of Service (QoS) Requested and Security Level in Connect PDUs
  • Expansion of information required in Connection Status Reports
  • Inclusion of alternative approaches for encoding the Element Identifier
  • Additional guidance on record generation determination
  • Inclusion of guidelines for determining AMA Call Type
  • Added rules and requirements for populating the Service Provider Identification information
  • Specification of Transaction-based Mode as the required method for transfer of PDUs to the BA whenever PDUs are generated by multiple Network Components (NCs) involved in a call or service transaction
  • Updated perspectives on the mapping of Diameter parameters to PDU usage data elements.

LSSGR: Switching System Generic Requirements for Call Control Using the Integrated Services Digital Network User Part (ISDNUP)

Issue 10, November 2007

GR-317 contains generic requirements for the procedures required to establish and release call connections using the Signaling System Number 7 (SS7) protocol. These generic requirements focus on basic interoffice voice calls that do not originate or terminate on Integrated Services Digital Network (ISDN) lines and on call connections that are either completely within one network or between distinct networks where an Interexchange Carrier (IXC) is not involved.

These requirements are based on SS7, a Common Channel Signaling (CCS) protocol defined by the International Telecommunications Union-Telecommunication Sector (ITU-T), and the T1S1.3 Working Group of the Alliance for Telecommunications Industry Solutions (ATIS) T1 Committee. The Telcordia specification of the SS7 protocol is provided in GR-246.

CCS is a method for exchanging information between Stored Program Control Switching Systems (SPCSs) that are interconnected via a network of signaling links. In switching systems where CCS is used for call connection signaling, out-of-band signaling messages replace Multifrequency (MF) and other inband interoffice signaling mechanisms on selected circuits. The out-of-band messages are used to report circuit seizure and transport address information, answer supervision, circuit release, etc.

Issue 10 of GR-317 includes:

  • An updated Section 3.1.1.6 with new requirements for receipt of ANM before ACM with and without backward call indicators
  • A new Appendix E that describes IMS and SS7 and IMS interworking.

Location Validation Database (VDB) Generic Requirements in Support of E9-1-1 Service

Issue 1, December 2007

GR-3130 provides generic requirements for the functions and interfaces that must be supported by a Validation Database (VDB) as a key element of the NENA i2 Solution. Many of the functions of the VDB described in this GR are expected to be extensible for support of location validation in the i3 Solution also.

The National Emergency Number Association (NENA) is in the process of defining a suite of solutions to enable emergency calls originated by Voice over Internet Protocol (VoIP) users to be routed to the appropriate Public Safety Answering Point (PSAP) for the geographic location from which the call was originated. The Long-Term Definition Working Group (LTD WG) of NENA is defining an architecture for an end-to-end Internet Protocol (IP) solution, referred to as an i3 Solution. The VoIP Migratory Working Group (VMWG) of NENA has defined a near-term solution that provides for migration toward the long-term view, while making use of the existing conventional E9-1-1 System Service Provider infrastructure. This is referred to as the i2 Solution. A revised version, referred to during its development stage as i2.5, is nearing completion for expected publication by early 2008. This GR reflects the revised i2 Solution.

The i2 Solution defined by the NENA VMWG includes a number of new functional elements to enable the pre-validation of location information, as well as the routing of VoIP-originated emergency calls and the delivery of the associated call and location-related information to the PSAP. These new elements and the associated terminology are described in this document. The critical network element that supports validating the location information that will be used subsequently to route a VoIP emergency call is called the Validation Database (VDB).

GR-3130 addresses the requirements on the VDB to process and respond to location validation requests received from any of the following three different types of entities:

  • Location Information Server (LIS)
  • VoIP Service Provider (VSP)
  • End user application.

This document has been reissued to align with current NENA documents. Changes have been made to:

  • Clarify entities that perform address validation
  • Describe use of the Emergency Routing Tuple (ERT) and provide more detail for Root Discovery consistent with the changes planned for Issue 2 of NENA 08-001, Interim VoIP Architecture for Enhanced 9-1-1 Services (i2)
  • Align with NENA 02-013, NENA Data Standards for the Provisioning and Maintenance of MSAG Files to VDBs and ERDBs, regarding use of MSAG data to populate the VDB database.

Methods and Procedures for System Reliability Analysis

Issue 2, November 2007

This document is intended to

  1. Guide reliability analysts, especially those without course work in mathematical reliability, in the creation and analysis of system reliability models.
  2. Guide personnel responsible for the purchase of telecommuni-cations equipment in requesting and interpreting system reliability analyses from vendors of telecom systems or other equipment.

Telecommunications consumers demand a high degree of availability of service, and telecommunications systems achieve this high availability by employing fault-tolerant architectures (e.g., redundancy for critical system components) and efficient fault detection and recovery mechanisms. The high reliability of the telecommunications network components thus makes the accumulation of system operating data needed to quantify long-term reliability, by straightforward methods, difficult, if not impractical.

System Reliability Modeling and Analysis (SRMA) is the means by which telecommunications systems reliability can be quantified. With the advent of new, complex architectures, there is a greater maintenance burden on a system owner. SRMA can quantitatively assess such burdens to determine whether a system can meet maintainability objectives with the allotted maintenance resources. It can also be used to optimize repair or maintenance strategies.

SR-1171, Issue 2:

  • Guides reliability analysts in the creation and analysis of system reliability models
  • Provides guidance on failure rate predictions (such as those made using SR-332) as key elements of a system reliability model
  • Guides personnel responsible for the purchase of telecom equipment in requesting and interpreting system reliability analyses from vendors of telecom systems or other equipment
  • Contains over 40 detailed diagrams and tables.

What's New in Issue 2?

  • Multiple formulas were updated to enhance clarity of exposition.
  • The document now aligns with other current issues of Telcordia documents (such as SR-332 and related GRs) for easy cross-reference of requirements and methodologies.
  • The "Failure Modes and Effects Analysis" section has been reorganized and updated with respect to objectives deemed necessary by Telcordia.

SONET Add-Drop Multiplexer (SONET ADM) Generic Criteria

Issue 2, August 2007

Add-Drop Multiplexers (ADMs) are critical components in emerging telecommunications and data transmission networks. Over 600,000 ADMs are deployed today.

A SONET ADM is a Network Element (NE) that provides either one or two "high-speed" SONET interfaces, as well as "tributary" interfaces at one or more of the various rates supported in the digital network. SONET ADMs are especially prolific in Core and Access Metropolitan Area Networks (MANs) in ring configurations.

GR-496, Issue 2, discusses specific features and functions for this SONET equipment, and aligns with the requirements in Telcordia GR-253, Synchronous Optical Network (SONET) Transport Systems: Common Generic Criteria. It also has been updated to reflect industry developments for ADMs during the last nine years.

GR-496, Issue 2:

NEBS™ Criteria Levels

Issue 3, July 2007

Equipment deployed in the network needs to be safe, reliable, and easy to deploy. The NEBS standards in GR-63, Issue 3, NEBS™ Requirements: Physical Protection, and GR-1089, Issue 4, Electromagnetic Compatibility and Electrical Safety - Generic Criteria for Network Telecommunications Equipment, provide uniform criteria for equipment design intended to reduce the cost of deployment and maintain reliability of the network.

SR-3580 groups the NEBS criteria into three functional levels (I, II, or III). Grouping the criteria into levels helps clarify the impact of non-conformance and allows the broad range of NEBS requirements to be judiciously applied to equipment, based on the equipment's application and impact on the operation of the network.

SR-3580, Issue 3:

  • Reflects the numerous changes made in the latest issues of GR-63 and GR-1089 criteria.
  • Groups the criteria levels to ensure they are applicable with current applications of network equipment.
  • Addresses the appropriate criteria for collocation as required by the Federal Communications Commission (FCC). This is particularly beneficial to service providers.
  • Tests to a level (1, 2, or 3) of environmental requirements to expedite deployments, without compromising the integrity of the base network.
  • Discusses how the criteria levels are particularly beneficial to emerging technologies, where rapid deployment is necessary to maintain competitive efficiencies.

NEBS requirements are the most widely used equipment design standards. They are highly specialized for the needs of the service providers, and have provided for robust and efficient equipment deployments for nearly 30 years.
