The Broadband Forum announced Tuesday the release of its “Splitter Testing” Technical Report 127 (TR-127), which specifies a system level test across four key IPTV network elements – the DSLAM, the CPE modem, the Central Office Splitter and the CPE Splitter.
TR-127 compliant splitters will prevent disturbance of the video signal by a telephone signal on the same line. They will reduce pixelization of the screen image and eliminate the restarting of the DSL Modem.
The new TR-127 enables quality delivery of triple-play services by maximizing the interoperability of splitters and in-line filters with xDSL transceivers in an active telephony environment, including on-hook, off-hook, ringing and ring trip events, which have proved to adversely affect the quality of IPTV service..
TR-127 addresses VDSL2 technology as well as ADSL2/2plus, and relates to the previously issued Technical Report 100 (TR-100), which covered ADSL2/ADSL2plus Performance Test Plans.
