Cable Installation

One end of the cable has a 100-pin connector that plugs into the front of the 24-Port Channelized
T1/E1/J1 ATM 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 attach 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).
