If the Media Module has an entry in the circuit plan and either of the other two conditions are not met, a MINOR alarm is logged.
A DS1 (MG-DS1, DS1-BD) differs from most Media Modules in that inserting the Media Module into the switch is not enough to make the board usable. It must also be administered with the add ds1 command.
To resolve this problem, either:
Refer to XXX-BD (Common Port Media Module) Maintenance documentation for details.
The value in the Aux Data field indicates the type of hardware problem:
| Aux Data |
Problem |
| 4352 |
External RAM failure |
| 4353 |
Internal RAM failure |
| 4355 |
Internal ROM failure |
If the board detects only one of these hardware problems, then the error will disappear when none of these faults are detected for 10 minutes. If the same Aux Data value is logged more than once in a 24 hour period, the Media Module should be replaced.
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 it does (10 times within 30 minutes), the Media Module should be replaced.
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 GGGVS, reset board GGGVS, test board GGGVS long, release board GGGVS. If the error recurs within 10 minutes, replace the Media Module.
This error occurs when a call is aborted because there are no available translation RAM locations for the call connection attempt. An alarm is raised if this error occurs two times within 10 minutes. Clear the alarm using the following commands: busyout board GGGVS, reset board GGGVS, test board GGGVS long, release board GGGVS. If the error recurs within 10 minutes, replace the Media Module.
Echo Cancellation errors are logged when:
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.
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.
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 MG-DS1 is restored to normal operation. All trunks or ports of the MG-DS1 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.
These errors are reported by the Media Module when it receives a bad control channel message from the switch. The auxiliary data identifies the following error events:
| Aux Data |
Event |
| 4096 |
Bad major heading |
| 4097 |
Bad port number |
| 4098 |
Bad data |
| 4099 |
Bad sub-qualifier |
| 4100 |
State inconsistency |
| 4101 |
Bad logical link |
This error will disappear when no faults are detected for 100 minutes.
This error is not service-affecting. No action is required. A Bad Translation RAM is detected, but the call continues by using another translation location.
If Error Type 1538 is also present, then the Media Module was taken out-of-service due to hyperactivity. If Error Type 1538 is not present, then the Media Module has not been taken out-of-service, but it has generated 50% of the messages necessary to be considered hyperactive. This may be completely normal during heavy traffic periods. However, if this error type is logged when the Media Module is being lightly used, it may indicate a problem with the Media Module or the equipment attached to it.
