E1 faulty

[ali-saleh]

Hello
It was noticed that communications were interrupted via E1 between two locations, and for your information, a detection of channels was made from SDH and it was working perfectly, knowing that there was an alarm in the PABX (E/W) on the electronic board (ADP). We hope that you will help me in fixing this malfunction. Some pictures of the condition of the PABX have been attached.
