VIC-2BRI-NT/TE activation problem?

[Akaffou Aristide Akaffou]

Hello,

I have a probleme to activate VIC-2BRI-NT/TE on Cisco router 1751V. I don't know what's happen because I think I made all the things to activate this card. Can you help me?

See in attached the output of show isdn status and show ip interface brief.

Thanks for your help.

Thank you Alex,

I wille try to do it.

So we have two lines, and the two BRI ports don't work simultaneously well, I thinK there is one which don't work very well.

Is there a slot issue? or what else?

Hi,

What is the actual issue ?

I see you are trying to emulate the network side of the ISDN.

Are you coonecting to a PBX ?

If you are then you need to sort out the TEI settings.
You do not negotiate TEI if you are the network end

Hi ,

If you are connecting to the Central Office you need to rebuild your configs like this:-
You are the user end not the network

!
interface BRI2/0
shut
 no isdn protocol-emulate network
 no isdn layer1-emulate network
 isdn point-to-point-setup
 isdn static-tei 0
 isdn incoming-voice voice
no shut
!

Depending on whether your service provider has set your lines for point to point or
point to multipoint you may need to remove the static tei

(In the UK for voice on ISDNse usually ask for point to point as
this caters for DDIs etc)

!
interface BRI2/0
shut
no isdn point-to-point-setup
no isdn static-tei 0
no shut
!

Use a isdn straight cable (They are colured orange and should have delivered with your router)
If you do not have the orange cables then a straight cat 5/6 cable should suffice
between your router interface and the service NTE.

Hope this helps
Regards
Alex
