    Need assistance - 924E PRI connection to PBX

    84mike New Member

      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 "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?

                      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...

                                  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

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

                              jwable Frequent Visitor

                              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
