Description

dsx1IntervalPCVs

.1.3.6.1.2.1.10.18.8.1.8

A Path Coding Violation error event is a frame synchronization bit error in the D4 and E1-noCRC formats, or a CRC error in the ESF and E1-CRC formats..

This is defined in RFC 1406

This can happen when:

Resolutions

Below are some basic troubleshooting steps

  1. Confirm that the Coding on your interface matches that of your circuit.

  2. Check the cabling to the device.

  3. Perform any vendor specific hardware tests on the device to determine if the device's hardware is functioning properly

  4. Call your circuit vendor to have them look at your circuit.

  5. Raise the threshold on the monitor. This will allow for better "tuning" of the application to your environment. Take care no to raise the threshold too much as this could allow important events to go unnoticed.
