Cables You Need
The POTS splitter card has three interfaces and each of the three POTS Splitter
card connectors requires a 50-conductor cable with a 50-pin Telco connector. Use
a minimum of 24 AWG.
Each DSL port at the DSLAM uses one pair of copper wires out of the 25 pairs on
each 50-position connector. The following tables show the cables that can be used
to connect 6050 and 7020 POTS splitter cards to the DSL interface at the DSLAM.
