Connecting the SFP Connector or the 10/100/1000 Connector

There are two Ethernet interfaces on the faceplate of the DSLAM, only one of which may be used at a time:

An 8-position modular jack providing support for 1000BaseT

ASmall Form-Factor Pluggable (SFP) socket providing, with the appropriate transceiver installed, support for 1000BaseX and 1000BaseT. See Appendix B, Equipment List.

Either interface can be used as the uplink for a single DSLAM, or for the terminating unit in a stack of DSLAMs.

To use the SFP connector or 10/100/1000 connector:

1Connect the uplink cable to the DSLAM:

—For a wire connection, plug the 8-position modular plug of your uplink cable into the 10/100/1000 modular jack. A straight-through cable can be used regardless of the destination interface, since the port automatically distinguishes between a Medium-Dependent Interface (MDI) and an MDI Crossover (MDIX).

Install the supplied small ferrite choke on the cable as close as possible to the jack. Use a cable tie to hold the choke in place.
