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.
