Telco 50-Pin Connector Pinouts for DSL Loops and POTS Splitters
The three Telco 50-pin receptacles on the rear of the
chassis (labeled for Slots 1, 2, 3) provide the 2-wire loop
interface from each DSL port to either the POTS splitter
card or, if the loop is not being shared with POTS, then
to the Main Distribution Frame (MDF). The following
table lists the pin assignments for each of these
interfaces.

NOTE:
When the 8610 chassis is the base chassis, the MCP is installed in Slot 1 and
the Tips and Rings for Slot 1 are not connected internally and are not active.
