Hi,
I would like to revise my previous inquiry regarding my posted topic.
I have 3 sites connected with E1 connections.
Site 1 being the main pabx with 3 cabinets about 200 local ines. Site 2 with 1 cabinet having 56 local lines. Site 3 having 1 cabinet and 32 lines.

Site 1 and site 2 is connected through an E1 50 pair copper wire installed about 10 years ago.
Site 1 and site 3 is connected through an E1 50 pair copper wire installed
about 2 years ago.

Problem is the E1 connection of site 1 and site 2 is the one that often disconnects. The basic thing that i would do is check the modem of both sites, but it's ok. So I will disable and enable the E1 cards,that connect both sites. Then, the connection is back to normal. The problem is recurring and I have a hard trying to find out what could be the cause of this disconnection.

Please help, any advice would be appreciated.

Thnak you.
