Connectivity issue with BRI to Nortel PBX

Endorsed Question
May 28th, 2009

Hi,

I have a 2811 router with VIC2-BRI-NT/TE and I am connecting this to a Nortel PBX, the cable that I use is a BRI cross over with pins 3 and 4 to 5 and 6. I have set my end as the network and have the following config, I don't have access to the Nortel PBX and only going by what the Nortel tech tells me.

interface BRI0/0/1

no ip address

isdn switch-type basic-net3

isdn protocol-emulate network

isdn point-to-point-setup

isdn layer1-emulate network

isdn incoming-voice voice

isdn skipsend-idverify

and when I do the show isdn status I get the following:

ISDN BRI0/0/1 interface

******* Network side configuration *******

dsl 1, interface ISDN Switchtype = basic-net3

Layer 1 Status:

DEACTIVATED

Layer 2 Status:

Layer 2 NOT Activated

Layer 3 Status:

0 Active Layer 3 Call(s)

Active dsl 1 CCBs = 0

The Free Channel Mask: 0x80000003

Total Allocated ISDN CCBs = 0

I have tried different switch types but I am not able to get the layer 1 up. Appreciate your help.

I have this problem too.

Right, so to put this one to rest for good I managed to get it working in the end, although a bit different. My configs are posted below; Nortel as the "network" and Cisco the "user"; I could only bring it up using QSIG. Oh, and I'm in Europe (Ireland) so had to use A-law on the BRI and cptone IE (tones and cadences for Ireland).

That's what worked for me. None of the other configs I've tried out there did the trick.

Hope this helps anybody who ever gets stuck with something similar.

Cheers guys!

- Verify that the interface is not shutdown by executing the show interfaces command.

- Verify that the switchtype is what the Telco specified by issuing the show isdn status command.

- If necessary, configure a different switchtype by issuing the isdn switchtype command.

- Verify that you have the appropriate BRI hardware (for example, U interface in North America and S/T interface in Europe).

- Verify the cabling and pinouts. You should also try swapping out the cables.

Hi there,

I'll be looking at setting up something similar in the coming days. Did you manage to get this working in the end? What was the catch to it?

Thank you

hadisharifi Thu, 01/16/2014 - 15:43

Hi, it was an issue on the Nortel PBX end and was fixed by them. My config was fine.

Tudor Adrian Negru Fri, 01/17/2014 - 04:52

Hi there hadisharifi,

I really appreciate the feedback. Now i just need to make sure I don't mess up the Nortel side of things (am doing both system ends).

Take care.

Kind regards,

Tudor

Hi hadisharifi,

So I'm facing these 2 systems, tried a lot of combinations but I have the same problem; I can't get the link up no matter what I tried so far (tried even QSIG type on both switches)..

You wouldn't be able to find out what exactly they changed on the Nortel side to bring this freakin' link up would you? I'd be very grateful for any info you'd be able to pass my way; I need to know what in blazez I need to change.

Many thanks.

Tudor

I am glad that you have got it working as I wasn't going to be much of help. I left the company along time ago and haven't been working on VOIP since then.
