I have 2x3845 with CEM E1 connecting to NEC PBX. the CEM circuit is up but i can't perform loopback test to the PBX to other PBX side.
I tried to use loopback network forn the E1 router controller, and i am getting nothing at the PBX site.
loopback local line from each Router to the PBX on the same site is OK.
Thanks & Regards
