Networks takes a leading role in the development of Quality of Experience and
Quality of Service recommendations for the deployment of IPTV over DSL. The Broadband
Forum’s Technical Report 176, “ADSL2Plus Configuration Guidelines for IPTV” co-editor
and contributor Dov Zimring also serves as Occam’s Director of Strategic Technology
and Solutions.

QoE and QoS requirements for the delivery of IPTV over DSL networks have presented
service providers with significant challenges. Noise and other changes to the DSL
transmission channel faced when deploying IPTV over DSL access or home networks have
at times resulted in packet loss and degradation in video quality. TR-176 enumerates
profile parameter guidelines for service providers to address this challenge and ensure
a consistent, high-quality IPTV experience to subscribers over DSL networks. The report
integrates input from service providers, equipment vendors and DSL silicon vendors
who recognized the importance of creating guidelines to support IPTV over DSL.

Future Broadband Forum reports will expand on TR-176 by including profiles for Dynamic
Spectrum Management/Dynamic Line Management and VDSL2 profiles for IPTV. The Broadband
Forum released TR-176 in September 2008 and includes it in the Forum’s BroadbandSuite
3.0 showcase at TelcoTV 2008.
