*Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the appropriate test description and follow the recommended procedures.
**If ports are assigned to the Media Module, then a minor alarm is raised. If no ports are assigned to the Media Module, then a warning alarm is raised. The alarm is raised after the Media Module has been missing for a period of 15 minutes. Warning alarms are also raised against any ports administered on the Media Module.
***Minor alarms on this MO may be downgraded to warning alarms based on values set in the set options command.
Major alarms on this MO may be downgraded to minor or warning alarms based on values set in the set options command.

Notes:

(a) Error Type 1

Indicates that the Media Module has totally stopped functioning or is not fully administered. The alarm is logged about 15 minutes after the Media Module has been removed or 11-minutes after the SAKI Test (#53) fails.

To be fully administered, a DS1-MM must meet all three of the following conditions:

Have an entry in the circuit plan using the change media module command
Be administered using the add ds1 GGGVS command
Be physically inserted into the correct slot

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. To resolve the error either:

Make sure that all conditions for administration are met and that a functioning DS1-MM is inserted in the correct slot, or
Completely remove the DS1-MM from the system using the following steps:

Remove any administered DS1 trunks, access endpoints or PRI endpoints associated with the Media Module from their trunk groups.
Execute the remove ds1 GGGVS and change media module GGGVS commands.
(b) Error Type 18 -- The MG-DS1 Interface Media Module has been busied out by a busyout board GGGVS command.
(c) Error Type 23 -- The MG-DS1 Media Module is not completely administered. To be fully administered, the MG-DS1 Media Module must:

Have an entry in the circuit plan using the change media module command,
Be administered using the add ds1 GGGVS command, and

Be physically inserted into the correct slot.

A DS1 (DS1-MM, 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.

(d) Error Type 125: No Aux Data

An incorrect Media Module is inserted in the slot where the DS1-MM Media Module is logically administered. To resolve this problem, either remove the incorrect Media Module and insert the logically administered Media Module, OR use the change circuit-pack command to re-administer this slot to match the Media Module inserted.

(e) Error Type 257

This error is associated with the Common Port Media Module Maintenance Test. Refer to XXX-BD (Common Port Media Module) Maintenance documentation for details.

(f) Error Type 513

The DS1-MM (MM710) has detected a transient hardware problem. 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.

(g) 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 it does (10 times within 30 minutes), the Media Module should be replaced.

(h) 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 GGGVS, reset board GGGVS, test board GGGVS long, release board GGGVS. If the error recurs within 10 minutes, replace the Media Module.

(i) Error Type 770

Unable to Write LAN Translation RAM Error. 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.

(j) Error Types 1400, 1401

Echo Cancellation errors are logged when:

Error 1400 - Echo canceller function failed. The Echo Canceller Function Test, which is executed by firmware, failed.
Error 1401 - Echo canceller memory failed. The Echo Canceller Memory Test, which is executed by firmware, failed.

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.

(m) Error Types 3073 to 3160

Error Type 3073 shows that this board is receiving slips and the AUX Data 'minus 3072' shows the last slip count reported.

(o) Error Types 3585 to 3601

Error Type 3585 shows that this board is receiving misframes, and the AUX Data 'minus 3584' shows the last misframe count reported.

(p) Error Type 3840

This error type is not service-affecting. No action is required. 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

(q) Error Type 3841

The DS1-MM (MM710) has detected a transient hardware logic error (for example, program logic inconsistency). This error will disappear when no faults are detected for 100 minutes.

(r) Error Type 3842

Bad Translation RAM Location Found Error. 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.

(t) Error Type 3999

indicates that the Media Module sent a large number of control channel messages to the switch within a short period of time. 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.
