OverviewOverview• The compendium summarizes direct or ancillary IP-related work

activity within TIA, either published or currently being developed. – Including high-speed access, interworking, terminal or infrastructure standards

that facilitate IP-based services and related wideband/broadband deployment.

• Overall, IP-related technical work is mainly being developed under:

– TR-30 (Facsimile Terminal Equipment and Systems), TR-34 (Satellite Equipment and Systems), TR-41 (User Premises Telecommunications Requirements), TR-42 (User Premises Telecommunications Infrastructure) and TR-45 (Mobile and Personal Communications Systems) Engineering Committees (TRs) and their Subcommittees and Working Groups. Additionally, Project MESA is indicating the importance of next generation technologies (including IPv4 and v6 functionality).

• Specifically regarding this GTSC Agenda Item, technical work is being addressed in TR-30, TR-41, TR-42 and TR-45 LAES Ad-Hoc.


TIA TR-30 Engineering Committee, TIA TR-30 Engineering Committee, Facsimile Terminal Equipment and Facsimile Terminal Equipment and

SystemsSystems• TR-30 is actively working on IP-based voice band modem technology

(i.e., MoIP and ToIP)– Including the control, maintenance, error-control, security and line signal

aspects of data modems and text telephony modems.– TR-30 regularly inputs to national and international standards bodies and

work related to modem development.• I.e., ITU-T SG 16 involving mechanisms to support the transport of voice-

band modem data over IP networks and the development of a global standard for the transport of legacy TDD/TTY signals over IP networks.

• Facsimile on the Internet is another area of development.– Includes the exchange of facsimile images.– Work in this area resulted in contributions to the ITU-T, which became part

of ITU-T Recommendation T.38, "Procedures for Real Time Group 3 Facsimile Communication over IP Networks" and Recommendation T.37, "Procedures for the Transfer of Facsimile Data via Store and Forward on the Internet."

– Contributions have also been generated within TR-30 for the support of ITU-T/IETF optional call control methods using SIP/SDP or H.248/MEGACO.


TIA TR-41 Engineering Committee, TIA TR-41 Engineering Committee, User User Premises Telecommunications Premises Telecommunications

RequirementsRequirements• TR-41 is actively involved with several IP-related areas:

– Multiline Terminal Systems.• End-to-end voice quality in IP networks.

– Analog and Digital Wireline Terminals.• Transmission Requirements for Narrowband VoIP and VoPCM Digital

Wireline Telephones.– Includes handset, headset and handsfree audio performance, IP-based

interfaces, PCM-based interfaces with codecs up to 64 kbits/second and QoS aspects involving VoIP.

• Transmission Requirements for Wideband Digital Wireline Telephones.– Applicable to IP and PCM.

– IP Telephony Gateways and Infrastructures.• Voice Gateway Transmission Requirements.

– Stand-alone IP transmission standard for telephony systems specifically involving Voice Gateways.

– Also involves performance and technical criteria for interfacing and connecting with various elements of public and private telecommunications networks and addresses impairments such as echo, noise, and distortion.



RequirementsRequirements– IP Telephony Gateways and Infrastructures (con’t).

• IP Telephony Support for Emergency Calling Service– Regarding solutions to the problem of locating VoIP terminals relating to E9-1-1

(emergency) services.» Including Location Identification and Callback Procedures for IP Terminals.

– Addresses Enterprise Networks (not terminals) connected through gateways and describes new network architecture elements needed to support emergency calling services and the functionality of those new elements.

• Performance/Interoperability Requirements for VoIP Telephone Terminals.– Involves defining performance and interoperability requirements for H.323-based

VoIP telephones and SIP-related aspects.

• IP Telephony Infrastructure Terms and Diagrams– In development—will define common vocabulary, definitions, acronyms and

nomenclatures with regard to IP-related documents.– Applicability to international usage is recognized.

• IP Telephony Security Framework– This project will address VoIP telephone network security architectural

considerations and the threat environment within the CPE/Enterprise space.» Includes authentication, authorization, privacy, and governmental

considerations in its scope. [Info also conveyed to IETF]

InfrastructureInfrastructure• TR-42 is actively involved with several IP-related or facilitative

areas:– Network Distribution Nodes.

• Currently reviewing proposals as a result of IEEE and Fiber Channel work showing clear support for a standard addressing data center facilities.

– With primary focus on information technology, including Internet data centers, service distribution nodes and storage area networks.

– These areas have been recognized as critical to the deployment of a number of next-generation standards.

– The scope will include topologies and performance for fiber, twisted-pair, and coaxial cabling, as well as other aspects of the IT infrastructure that will enable these facilities to rapidly deploy new technologies, such as emerging 10 Gb/s networks.

– Requirements will consider the need for flexibility, scalability, reliability and space management.

– Telecommunications Copper Cabling Systems.• Involves Category 6 cabling that facilitates advanced services.

– Telecommunications Optical Fiber Cabling Systems.• Facilitating additional/advanced component and transmission requirements.

– Capable of supporting 10 Gb/s serial transmission.


TIA TR-45 Engineering Committee Ad TIA TR-45 Engineering Committee Ad Hoc, Hoc, Lawfully Authorized Electronic Lawfully Authorized Electronic

Surveillance (LAES)Surveillance (LAES) • This Ad Hoc group initiated a joint project with ATIS Committee T1,

relative to Communications Assistance for Law Enforcement Act (CALEA) compliance and refinement of existing standard.– Including requirements specific to individual packet mode technologies.

• Also punch list (i.e., additional capabilities) items.

– TR-45 welcomes participation by parties with a material interest in packet mode communications involving a broad range of systems and technologies and their interface to the Collection Function.
