Connecting the Interface Cables and Checking the LEDs
The CES PAM can support interfaces that connect to the following physical layers:
•
E1 G.703 with HDB3 coding
•
E1 2.048 Mbps coaxial cable
Connect the CES interface cables as shown in Figure 8-3. For detailed descriptions of ATM
cabling requirements, refer to the sections "Distance Limitations" and "ATM Connection
Equipment" in the chapter "Preparing for Installation."
CES T1 and E1 Module LEDs
This section describes the LEDs on the faceplate of the CES modules, shows their possible
illumination states, and defines the operational status of the associated ports, given certain
illumination patterns of the LEDs.
The LEDs provide status information for the port adapter module's individual BNC and
twisted-pair interface connections. The LEDs are shown in Figure 8-3.
