Introduction :
This product specification (PS) document specifies the electrical requirements, connectors and mechanical issues for VDSL over ISDN/POTS splitter.The main purpose of the splitter filters is to separate the tele-band signals (originated from POTS or ISDN  –BRA). A second purpose is to isolate poorly balanced tele-band equipment from the line at VDSL band frequency in order to prevent unwanted egress( and ingress) from VDSL signals.
