3.1.1 VDSL and POTS Connections

Connect the lines from the user equipment (VDSL modem) to the VDSL LINE port and the lines from the central office switch or PBX (Private Branch Exchange) to the POTS/ISDN LINE port. Make sure that the VDSL LINE Telco-50 cable and the POTS/ISDN LINE Telco- 50 cable are not shorted on the MDF (Main Distribution Frame).

The line from the user carries both the VDSL and the voice signals. For each line, the switch has a built-in splitter that separates the high frequency VDSL signal from the voice band signal and feeds the VDSL signal to the switch, while the voice band signal is diverted to the POTS/ISDN LINE port.

Refer to Appendix on page 275 for Telco50 pin assignments.
