One end of the cable has a 100-pin connector that plugs into the front of the 24-Port Channelized
T1/E1/J1 CEoP SPA. Use the thumbscrews on either side of the connector to secure the cable to the SPA.
The other end of the cable has two 50-pin Telco connectors that can be attached to the rear of a
24-port RJ-45 patch panel. Both connectors are identical: one is for Transmit (TX) and the other is for
Receive (RX).
