h. Error Type 514: LAN External RAM Error.
This error occurs when there is a hardware fault in the PPE external RAM. The RAM is
used for message buffering to and from the Packet Bus. This error should not occur
frequently. If does (at least 10 times within 30 minutes), the Media Module should be
replaced.
i. Error Type 769: transmit FIFO Underflow Error.
This error occurs when the Media Module cannot find the end of frame bit when
transmitting a frame to the Packet Bus. An alarm is raised if this error occurs three times
within 10 minutes. Clear the alarm using the following commands: busyout board
location, reset board location, test board location long, release
board location. If the error recurs within 10 minutes, replace the Media Module.
j. Error Type 770: Unable to Write LAN Translation RAM Error.
This error occurs when there are no available translation RAM locations for a call
connection attempt. An alarm is raised if this error occurs twice within 10 minutes. Clear
the alarm using the following commands: busyout board location, reset board
location, test board location long, release board location. If the error
recurs within 10 minutes, replace the Media Module.
k. Error Type 1025: This error is not service-affecting and no action is required.
l. Error Types 1400, 1401: Echo Cancellation error.
Echo Cancellation errors are logged when:
● Error 1400 -The Echo Canceller Function Test failed.
● Error 1401 -The Echo Canceller Memory Test failed.
This error indicates that Echo Cancellation is no longer being supplied by the board. Clear
the alarm using the following commands: busyout board location, test board
location long, release board location. If Test #1420 (Echo Canceller Test) fails,
replace the Media Module.
m. 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 is alarmed. To clear the alarm and restore the board to the Packet Bus, use
the commands busyout board location, reset board location, test board
location long, release board location.
If the problem persists and there are no PKT-BUS alarms or port alarms, replace the
Media Module.
n. Error Type 1538: The hyperactive Media Module is out-of-service and may exhibit one or
more of the following symptoms:
