PRI config guide on ISR 2800-UAE

Unanswered Question
Feb 26th, 2009


I have terminated PRI into ISR 2800. All config is ok interims linecoding, framing, clock source etc. PRI line is tested by ISP-Ok.

But it shows E1 down in sh commands with the status LED yellow.

Is there any specific setting to be done for UAE regions??

I have this problem too.

Send output of "show controller E1", and check your cabling.

E1 is the same in all the world.

What is the cable that goes from router to telco ? Is telco 120 Ohm / unbalanced ?

Do you mean pins 1-2 and 4-5 of RJ-45? Are you respecting pair twisting ?

After the cable is OK, if still problems, the circuit is defective. There are no other alternatives.

Invite SP on premises and have them place and receive calls using a test device, in front of you.
