[cisco-voip] RV: layer 2 varies between TEI_ASSIGNED and AWAITINGESTABLISHEMENT

Wed Nov 21 12:08:12 EST 2007

Including cisco-voip list since Ralil is having issues sending.

The first that jumps out at me is the linecode violations.   Have you  
tried changing this setting (it is not defined in your config below)  
to see if you can clear those up?

Subject: RE: layer 2 varies between TEI_ASSIGNED and  
AWAITINGESTABLISHEMENT

Hello dears:
My problem is that. I can´t connect E1 (direct from pbx) to router  
cisco 2801 with IOS Version 12.4(3g).
The layer 1 is ACTIVE STATE but the layer 2 change between  
TEI_ASSIGNED and AWAITING ESTABLISHEMENT.
I test with different encapsulations (ppp, hdlc)  and different  
signalling (qsig, net5), in other router with identical hardware,  
configuration and IOS connect without problems and automatically (The  
PBX or cable is not the problem)
Nothing change if reload the router, reinit interface serial0/2/0:15  
or e1, clear counter, etc.
When I debug q921 on I don't receive Rx, only TX out from cisco 2801.

How know if the card VWIC in the router is the true problem?
Thanks.

(sorry for my English)
