Extension Line (Disturbances) Error

Default definition: |  | ERROR |
Used by block: |  | EX |
Category: |  | MAINTENANCE |

The signalling between the exchange and the telephone / equipment is not working properly. The reason could be a faulty telephone, faulty ELU-card, too long telephone lines, disturbances in the communication, etc. Note that a real line fault, caused by the fact that a telephone is unplugged, does NOT cause a warning. This warning is only used, as mentioned earlier, when the signalling is more or less OK, but not good enough.

- D1: Card position for the extension
- D2: Individual number for the extension.
- D3: Main reason for the warning, see the LINERR-message for details.
- D4: Detailed reason for the warning, see the LINERR-message for details.

#### Recommended action

If the error occurs too often, try the following steps:

- Replace the telephone.
- Check the installation for loose connections, etc.
- Replace the ELU-board indicated by data in D1 (hex-value).
- Try with shorter lines, to see if the line length affects the problem.
