ATM P ro ble ms

Table 8-3. ATM Problems

Symptom Possible Cause Solutions

Out-of-Cell Delineation

(OCD) events; loss of

cell delineation.

Line impairments. Check DSLAM statistics.

Reducethe link rate.

The unit should be

receiving data, but the

ATM statistics indicate

that the VCs are not

receiving data.

The Virtual Circuit (VC) is

improperly configured or not

configured in the DSLAM.

Check DSLAM statistics.

Configure the VC.
