Hardware Overview
This chapter describes the front panel and rear panel of the switch and shows you how to make
the hardware connections.
3.1 Front Panel Connection
The front panel contains switch LEDs and all the network ports and port connections.
Figure 5 Front Panel
The following table describes the port labels on the front panel.
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.
