2 E1s IP406 problem

[iroba]

I have an IP406 with 2 E1s, they are in different slots, i don't why suddenly both cards drop all the calls, this happens every 2 hours, I have the same configuration for both E1s, I have the clock as Network, the version is 2.1.27, do you have a similar installation working?

I'm using E1R2

Hi iroba.

Set first E1 to clock off of the network and set the 2nd E1 to clock in fall back.

It looks like a sync error

A good quality Isdn Tester in monitor mode would fine out where the problem lies.I would not think the ISDN cards sre faulty.

I would also suspect synch problems
use the monitor programm to monitor the ISDN & you will probably see a synch error msg just befor the circuits drop
