Echo Cancellation is no longer being supplied by the board. Clear the alarm using the following
commands: busyout board GGGVS , test board GGGVS long , release board GGGVS .
If Test #1420 (Echo Canceler Test) fails, replace the Media Module.
• (k) Error type 1537
LAN Bus Timeout Error. This error occurs when the Media Module transmits too many bytes on
the LAN bus for a single frame. This condition may be caused by an on-board fault or by faulty
data received on one of the Media Module's external ports. If any of the ports on this Media
Module are alarmed, refer to the repair procedures for those maintenance objects.
If the error occurs three times within 10 minutes, the board is isolated from the Packet Bus and the
board alarmed. To clear the alarm and restore the board to the Packet Bus, use the commands
busyout board GGGVS , reset board GGGVS , test board GGGVS long , release
board GGGVS .
If the problem persists, and there are no PKT-BUS alarms or port alarms, then replace the Media
Module.
• (l) Error Type 1538
The hyperactive Media Module is out-of-service and may exhibit one or more of the following
symptoms:
- The common Media Module level tests such as Test #50 abort with error code 2000
- The tests run on the ports of this Media Module return a NO-BOARD result
- A busyout/release of the Media Module has no affect on test results
- A list configuration command shows that the Media Module and ports are properly
installed
The Media Module is isolated from the system and all trunks or ports on this Media Module are
placed into the out-of-service state. The system will try to restore the Media Module within 20-30
minutes. When no faults are detected for 20-30 minutes, the DS1-MM is restored to normal
operation. All trunks or ports of the DS1-MM are then returned to the in-service state.
If the board is not restored to normal operation, or the error recurs after the board was restored to
normal operation, escalate the problem.
