Troubleshoot ATM Transmission Faults

Troubleshoot ATM Transmission Faults

Common measures to troubleshoot ATM transmission faults include a layer-by-layer check and a segment-by-segment check. 

Usually, find out the faults by a segment-by-segment check, then determine the fault type by a layer-by-layer check, and finally locate the root cause.

The way we can use to check ATM TX alarm:

Layer-by-Layer Check

Check whether the layer where faults occur is abnormal.

l   If yes, rectify the fault and then check whether the fault is cleared.

If yes, the fault is cleared.

If no, check whether the next layer is abnormal.

l   If no, check whether the next layer is abnormal.

If yes, check the fault layer by layer (from the present layer to bottom layer).

If no, the fault occurs at this layer.

Segment-by-Segment Check

Divide an end-to-end network into segments, and check a fault segment by segment.

Good to know the idea.
