Need assistance - 924E PRI connection to PBX

[Anonymous]

I have an Avaya PBX here, and I am attempting to connect an Adtran 924E thru a PRI connection. I have a SIP circuit coming into the Adtran on NET1, and I am trying to use NET4 to connect the PBX. Our phone system version is not updated enough to do SIP trunking, which is why I am trying to use a PRI.

I have tried going thru https://supportforums.adtran.com/docs/DOC-2254, but I was unsuccessful. If anyone has a config they could post for example, that would be great!

Here you go:

interface t1 0/4

  tdm-group 1 timeslots 1-24 speed 64

  no shutdown

interface pri 1

  description pri 1

  connect t1 0/4 tdm-group 1

  role network b-channel-restarts disable

  no shutdown

isdn-group 1

  connect pri 1

ip sip

ip sip udp 5060

voice feature-mode network

voice forward-mode network

voice trunk T01 type sip

  description "SIP Trunk"

  sip-server primary X.X.X.X (IP Address of ITSP)

voice trunk T02 type isdn

  description "PBX"

  resource-selection circular ascending

  connect isdn-group 1

  rtp delay-mode adaptive

voice grouped-trunk VOIP

  trunk T01

  accept $ cost 0

voice grouped-trunk PRI

  trunk T02

  accept $ cost 0

Let me know if you have any questions.

I had most of that in the config...my problem is the connection between the PBX and the Adtran...

On the PBX, I have a signaling group showing "in-service", but all the ports in the trunk group show "out-of-service-FE"

Just for clarity, I have to use a T1-cross cable to connect the 2, correct? Maybe I have something set incorrectly on the PBX side...

I really appreciate the help!

Is the Adtran showing that the PRI is up?

Are there any errors?

[Anonymous]

The interface shows UP in the Adtran, although I am seeing CSS errors on T1 0/4...I'm not sure what that means.

The presence of CSS errors indicates that there is either two timing sources on the T1 interfaces or no clock at all.

You can issue the command "show system" to see the timing source configuration and active timing source on the unit.

You can change the timing source by the command "timing-source <internal | t1 0/X>.

I am using the provider's T1 as the timing source...

"timing-source t1 0/1"

Based upon the errors the timing on 0/1 is good the problem is on  0/4.

Try the following:

timing-source t1 0/1

timing-source internal secondary

[Anonymous]

I have done so...still getting CSS errors. Also, still no B-channels.

What's the phone system's settings for the PRI?

It looks like you have both the Adtran and PBX set to "network".

Try setting the PBX to "user".

[Anonymous]

Changed DS1 to "Connect:pbx / Interface:user"

Same result. No B-channels.

[Anonymous]

Pull out the PRI in 0/4 and plug it back in.

Did the errors clear?

[Anonymous]

I really appreciate you taking the time to help me out. Unfortunately, no change yet.

[Anonymous]

As far as the config goes it looks OK.

If you are still having timing issues I am not sure what else to try. (Maybe reboot everything?)

Perhaps someone from Adtran can suggest something.

[Anonymous]

Mike,

   Try setting your timing source to the PRI interface instead of the data interface, I usualy set it that way because my data connection is on eth 0/1 instead of T1, but I am wondering if there is a timing mismatch because the data and voice configuration run at differently.

timing-source t1 0/4

!

timing-source internal secondary

!

Also not sure if the PBX requires it but you should also added the following to you pri interface:

interface pri 1

digits-transferred 7 (insert what your PBX expects)

A couple of times  I have had to add the following to the isdn-group to get some PBXs to connect properly:

isdn-group 1

  min-channels 1

And finally I did not see your Voice configs in your example config so be sure you have the following added:

voice trunk T01 type isdn

  description "PRI"

  resource-selection circular descending

  connect isdn-group 1

  rtp delay-mode adaptive

!

voice grouped-trunk PRI

  no description

  trunk T04

  accept $ cost 0

!

And finaly you will need to ensure your SIP trunks are configured properly

Hope it helps

Also here is another post that maybe similar to your issue:

I appreciate the help. Still unsuccessful. Can you confirm I should be using a T1-cross cable? I can't even get a D-channel with a straight cable. I have even contacted Adtran support, and have been told the config looks good. Frustrating.

[Anonymous]

I guess it doesn't hurt to try.
