Good day Cisco Guru's
I curently have a 2 port Multi-channel T1\PRI card in a 7206, I am using port zero with a T1 Card and I configured very minmally and it operates fine, Port 1 is connected to the sdame type of Card and I cannot get my port to come up. If I swap the cables around Port 1 Does come up.It is a very confounding thing.
I am a novice with WAN routing so I am probably missing something easy, So I posted my "Sh Int" and "sh run" two Ser ports I am talking about. any help would be greatly appreciated

If you swap cable from a port to another, and interface remains down, that indicates hardware fault, and there is nothing you can do about it beside having it replaced.
04-09-2010 12:34 PM
Thanks for the reply
That is trhe confounding thing to me, If I move the cable I have in Port Zero which is Up and Up to Port 1, the interface DOES come up.and If I move Port 1 (currently not functioning) to the operational port 0, it DOES NOT come up. SO I am fairly confident the harware is working
04-09-2010 01:56 PM
It is a bit difficult to follow you.
How many "cables" there are?
What is on the other end of the "cables"?
04-09-2010 02:38 PM
Let me ask this question instead. I have one circuit that connected to another 7206 with a PRI\T1 Card at the far end, This circuit is up and good. The circuit that is not coming up is connected at the other End to a CISCO 3845 using an HWIC-1DSU-T1 Module. Could it bh a compatibilty issue?, But even if so wouldn't the interface at least show up if it was being properly timed and synced with the DSU/CSU card in the cabinet?
04-09-2010 02:39 PM
Take "show controllers T1" at both ends of the circuit.
Has the circuit ever worked before, or it is a new one ?
04-09-2010 02:51 PM
No, It is a new one, So I am trying to use the current 3845 vI have in this location in conjuction with a 7206 here
The 3845 does not have a "T1 Controller" per say, I know that this module shows up as serial 0/0/0 with my IOS of 12.4(T) It is sup[posed to act as a T1 controller
I Already have a T3 in use in it

For that type of T1 interface, use "show service-module serial". However, it is clear already from show interface that there is loss of signal, same thing on 7206 side.
Most likely the circuit has not been completed/activated, despite whatever claim telco is making.

I believe you are absolutely correct, even though I have fought with them, they keep telling me it is "premise equipment" and close my ticket. So I just want to be absolutely sure I am not missing anything before I go back and get a little more undiplomatic with them.

This side has signal, but loss of framing. Another indication of a messed up circuit, as by now ESF is the only framing used on new circuits.
There are various loopbacks that could be done to rpove your case, some by you some by telco, but I don't think is even necessary to do that.
The key on a new circuits is: has acceptance been signed ? If not, they cannot even bill you for.
