Chapter 4 Flexible Interface Cards (Router 6000)

Step 1: Connect the SMB connector of an E3/T3 cable to the Tx port on the Router 1-Port T3 ATM FIC and another end to the Rx port on another device.

Step 2: Connect the SMB connector of another E3/T3 cable to the Rx port on the Router 1-Port T3 ATM FIC and another end to the Tx port on another device.

Step 3: Check the behavior of the LINK LED on the Router 1-Port T3 ATM FIC panel: OFF means fault occurs on the line and the signal is out of synchronization. Check the line status.
