PRI Problem

[pointedout]

I have a PRI with Ericson MD110. It was going fine however 4 days back we got an issue. External caller was not able to call on our Operator root (separate group of channels). Incoming call is coming in this manner:

Please guide.

looks like a protocol mismatch

Assuming you have reset DCH and T1

verify DCH IFC is correct with far end.

I have split 30 channels into 20 + 10. 20 are in one route and 10 are on other. This issue is happening on 10 separate channel. If IFC was the issue, other 20 channels must exhibit the same problem, what you say?

 

[bhassell2000]

check the IFC in the route the 10 channels are on

Thanks,

Buddy

IFC for route would have to match DCH so can't imagine routes could have a different IFC.

So one route works ok but other route does not? Wonder if Ericson switch could be setup different for this different trunk group?

What does telco say about those incoming setup messages?
