setup voice PRI T1 using VWIC2-2MFT-T1/E1

I am trying to setup PRI T1 using VWIC2-2MFT-T1/E1. I wasn't able to bring up this T1 with local provider. This is what I have on my router.

***************************

isdn switch-type primary-ni

!

controller t1 0/0/0

framing esf

lincode b8zs

pri-group timeslots 1-24

!

interface Serial0/0/0:23

no ip address

encapsulation hdlc

isdn switch-type primary-ni

isdn incoming-voice voice

no cdp enable

*******************************

Anything do I have to worry about to bring this T1?

Thanks.

Peter

Re: setup voice PRI T1 using VWIC2-2MFT-T1/E1

Hi Peter,

Since this is a voice circuit, I'd try removing the "encapsulation hdlc" on the Serial0/0/0:23 statement.

Also, you didn't mention what platform you're using this VWIC2 on. I have done a number of deployments on the 2821 ISR platform, which required additional configuation to bring up the VWIC with the provider. I use:

network-clock-participate wic 0

network-clock-select 1 t1 0/0/0

Hope that helps,

i tried to remove the "encapsulation hdlc" from the same interface on a router that I have, and it takes the command with no errors. But when I do a show run, "encapsulation hdlc" is still on the interface. Am I correct in assuming that it is there by default, but does not normally show up in the config?

Peter,

Did my suggestion provide any traction for your issue?

JFO and Peter,

I have seen that hdlc encap command in the new 12.4 IOS. Doesnt do any harm though. You cannot remove it.

Peter, what does a show isdn status give ya ?
