ATIS’ Network Interface, Power, and Protection (NIPP) Committee Dynamic Spectrum Management (DSM) • Goal is to improve reliability and increase data rates through measurement and/or dynamic management of DSL spectral density • Bandwidth in the access remains a major item and this is especially true for copper-based access loops (i.e., the territory of DSL) • DSM will allow network providers to manage bandwidth (i.e., allocate bandwidth for use and recover bandwidth that could otherwise be lost when terminals using that bandwidth are turned off) • DSM has the potential of being a significant asset as the telecommunications world moves into realm of IPTV • Initial draft is currently out for ballot GSC: Standardization Advancing Global Communications
ATIS’ Network Interface, Power, and Protection (NIPP) Committee VDSL2 (Very-high-bit-rate DSL) • Since GSC-10, NIPP has worked on completion of the VDSL2 standard and enhancements • Focus on moving ITU-T SG 15 VDSL2 Recommendation to completion (approved in May 2006) • 38 contributions toward VDSL2; 10 addressing further enhancements of VDSL2 and ADSL/ADSL2+ • Potential uses include IPTV • Standard includes bandplans, power spectrum densities, total transmit power, dynamic rate partitioning • Cooperative work under way with TIA TR41.9 to address the TIA-968 conformance criteria for the newly approved VDSL2.

ATIS’ Network Interface, Power, and Protection (NIPP) Committee Network End Line Sharing Splitter Standard • Describes electrical characteristics of 4 line sharing splitters that may be used to deploy DSL technologies over metallic lines also used to provide voice-band service • Protection for DSL signals from PSTN high frequency transients and impedance effects (ringing, ring-tip, off-hook) • Recently completed additions to the splitter requirements for ADSL, VDSL1, VDSL2 GSC: Standardization Advancing Global Communications
