Telco 50-pin Connector Pinouts for DSL Loops and POTS Splitters
The 18 Telco-type 50-pin connectors on the rear
of the chassis 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, to the Main Distribution Frame (MDF).
The following table lists the pin assignments for
each of these interfaces.
NOTE:
The above table lists the port assignments of the slots and their respective
connectors for 25 ports. DSL port cards with less than 25 ports have their
ports assigned in ascending order starting with port 1. For example, a 12-port
DSL card uses Ports 1 through 12, while Ports 13 through 25 will not be
connected by the port card.
