Troubleshooting: ATM Connectivity
The ATM physical layer provides a mechanism for monitoring cell delineation. The cell delineation function allows the identification of cell boundaries in the payload. The emweb:EwSysModeCurrentLC; software monitors Out of Cell Delineation (OCD) alarms which indicate that there are errors found in the payload. If the OCD condition persists for greater than 2.5 seconds, it will cause the DSL line to retrain.
You can test the health of the ATM link by manually sending Operations and Maintenance (OAM) cells over a specified virtual connection. This command requires the specification of:
•OAM loopback cell type - either F4 or F5
•Transmit over a single LAN segment (one hop) or
•VPI/VCI number of connection to transmit OAM cell over
The response section of the web page will indicate if an OAM reply has been received for the transmitted OAM cell.
