1.T2 and T3 cable length should be set to “short” upon power-up for self-test. Upon LOS, defaults to “internal synchronization.”

BPX, IGX, or IPX Port Configuration

The trunk on the BPX, IGX, or IPX node must be reconfigured from Cisco StrataView Plus or a local control terminal.

Step 1 Telnet to the first node equipped with an AT3-6ME.

Step 2 Use the Configure Trunk (cnftrk) command to select T2 for the Tx Trunk Rate.

Step 3 Set the RCV Trunk Rate to 28980 cps.

Step 4 Repeat steps 1 through 3 for all other nodes using the AT3-6ME.

Operation

The following paragraphs describe the various operating modes for the AT3-6ME. The unit is basically designed for unattended operation. Any failures in the unit or any line alarms or errors will be propagated.

Power-Up Sequence

During the system power-up, the unit goes through a self test procedure. The Power LED turns green. The Active/ Fail LED stays off until the self test sequence is completed. At the end of the self test the loop LED comes on for about 5 seconds.
