Telco 50-pin Connector Pinouts for DSL Loops and
POTS Splitters
The three Telco 50-pin connectors on the Interface Module provide the
two-wire loop interface from each DSL port to either the POTS splitter shelf or,
if the loop is not being shared with POTS, then to the Main Distributing Frame
(MDF). The following table lists the pin assignments for each of these
interfaces. Note that Pins 25 and 50 are
not used.
