Connecting the Interface Cables and Checking the LEDs
All CES interfaces are bidirectional. You must use the appropriate CES interface cable to
connect the CES BNC or twisted-pair PAM interface with an external CES network.

CES Connection Equipment
For CES traffic over twisted-pair, use the RJ-48C connect to connect the CES T1 PAM or
CES E1 PAM to the external CES network. See the section "Preparing Network
Connections" in the chapter "Preparing for Installation" for a description of an RJ-48C
connector and twisted-pair and shielded twisted-pair cable.
For coaxial traffic, use the BNC connector to connect the CES E1 PAM with the external
CES network. See the section "Preparing Network Connections" in the chapter "Preparing
for Installation" for a description of a BNC connector and coaxial cable.
CES T1 and E1 PAM Network Connections and LEDs
The CES T1 and CES E1 PAMs provide an interface to CES switching fabrics for
transmitting and receiving data at up to 1.544 Mbps (T1) and 2.048Mbps (E1)
bidirectionally. The PAM LEDs provide status information for the port adapter module's
individual interface connections.
Caution
