TIA Engineering Subcommittee TR-30.3, Data
Communications Equipment Evaluation and
Network Interfaces
• TR-30.3 recently completed ANSI/TIA-921, “Network
Model for Evaluating Multimedia Transmission
Performance Over Internet Protocol”
– This new standard is in the publication cycle
– Undergone over two years of work to ensure that the model
accurately depicts how IP networks behave
• Model’s characteristics have been favorably compared to actual
network traces and performance measured by, and provided to the
committee, by several network operators
– This model has already been used in commercially available test
equipment for testing network-connected devices
– Work has also been presented to TIA TR-41, User Premises
Telecommunications Requirements and has been introduced
to ITU-T Study Group 12 as Contribution toward a potential ITUT Recommendation (P.VTQ)
– TR-30.3 is now expanding its work with the next revision of the
standard to include network models for wireless and cable IP

TIA Engineering Subcommittee TR-34,
Satellite Equipment & Systems
• In 2005, TR-34 completed development of TIA-1039-A,
“QoS Signaling for IPv6 QoS Support”
– After incorporating certain revisions, this standard
was balloted and approved
– IPv6 QoS Option Field in TIA-1039 requests QoS for
network setup
– QoS Signaling Protocol Extensions
• Enables End-to-End QoS setup with IP

TIA Engineering Subcommittee TR-34,
Satellite Equipment & Systems
(Continued)
• Committee TR-34 also looked at how Connection Control
Protocol (C2P) inputs from ETSI/DVB could be utilized in a
Satellite Network Modem System standard
• TR-34 took the lead in developing TIA-1088, “Satellite
Network Modem System (SNMS) Mesh Control Protocol,”
which was approved for balloting in 2005
• TR-34 continues to work toward the publication of a joint TIA
and ETSI C2P standard for DVB/RCS
– Further refine standard to determine how connection request
profiles relate to channel capacity and how Return Channel
Satellite Terminal (RCST) determine their rate parameters from
the profiles
– Also be important in the future to ensure that the C2P standard
will support important functionality such as QoS, encryption and
the generation of dummy traffic

TIA Engineering Subcommittee TR-45,
Mobile and Personal Communications
Systems Standards
• Committee TR-45/3GPP2 continues to progress
QoS developments to support real-time services,
including speech
• Latest Revisions of TIA-2000 and TIA-856 utilize
an all-IP based architecture
– QoS of internet access
– QoS management
• QoS support for Wireless Packet Data
Networking in cdma2000®
• QoS development also for EGPRS-136
