CE1/PRI Interface Fails to Communicate with an E1-F Interface

CE1/PRI Interface Fails to Communicate with an E1-F Interface

Fault Symptom

A CE1/PRI interface fails to communicate with an E1-F interface.

Procedure

  1. Ensure that the CE1/PRI interface and E1-F interface use consistent working modes.
    • If the CE1/PRI interface works in E1 mode (configured by the using e1 command), the E1-F interface must work in unframed mode (configured by the fe1 unframed command).
    • If the CE1/PRI interface works in CE1 mode (configured by the using ce1 command), the E1-F interface must work in framed mode (configured by the undo fe1 unframed command).

      In this case, bundled timeslots (configured by the channel-set command) on the CE1/PRI interface must be the same as those (configured by the fe1 timeslot-list command) on the E1-F interface.

  2. Ensure that the CE1/PRI interface and E1-F interface use the same CRC mode, encoding and decoding mode, and data inversion mode.
