Using TA908 as a PRI tester

Jump to solution

I have a few PRI PBX interrface cards I would like to test and see if they work using a TA908e, How can I configure the TA908e to send a call from FXS0/1 out T1 0/3?

Thank you

interface pri 1
  description pri 1
  isdn name-delivery setup
  connect t1 0/4 tdm-group 1
  digits-transferred 7
  role network b-channel-restarts disable
  no shutdown


On one (but not both) of the units modify PRI 1 as follows:

interface pri 1

  ....

  role user

  no shutdown


This will be the one acting like PBX.  The other will be acting like a carrier but it really doesn't matter.

Also on one of the units enter:

timing-source internal

(this is default and won't show in the configuration)

On the other enter

timing-source T1 0/4

It doesn't matter which one is which.

You've got digits-transferred 7 but you've got 3-digit extensions.  This might cause some dialplan issues. Try digits-transferred 3 or configure your users with 7-digit numbers.  ISDN and voice debugs will help once you get the units up and in sync.

By the way, good for you!  A lab environment is the place to test and learn, not a customer's phone closet with your cell battery about do die while on hold to Adtran support.

Re: Using TA908 as a PRI tester

Create a PRI interface on the T1, there is lots of documentation on this. Add it to a trunk, and the trunk to a grouped-trunk with some dialed digit pattern.

Connect a phone to FXS 0/1 and dial a pattern matching that of the grouped-trunk.  You can assign a voice user to the FXS port and ring the analog phone from the PBX too.

Standard debugs that will help

  debug isdn l2-formatted

  debug voice verbose

If you have several cards, you can connect two of them to T1 0/3 and T1 0/4 and place calls between them as well.

Thank you for the speedy reply however my config did not work, I was not sure if the problem is with my PBX or interface card so i configured a second TA908 just like the 1st and I am trying to complete a call from FXS 0/1 from TA908-A to FXS 0/1 on TA908-B using a T1 cross-over cable Whewn I place a call from A to B the Voice Verbose shows a "Class of Service error" and Voice debug on TA908-B shows nothing. Please take a look at my config and let me know what to do

Thank you

[snip]



voice grouped-trunk GROUP1
  trunk T01



At this point in the configuration, add the dial pattern you want to present to the PRI.

For example if you are going to send extensions 300 through 399, enter:

config t

voice grouped-trunk GROUP1

accept 3XX cost 0

Now if you call 300 from the FXS phone you should see it presented to the PRI.

Hmmm...  Is the PRI up?

What do you get with

show interface t1 0/3

show interface pri 1


if show interface t1 0/3 is down, you have a physical problem with the T1, you may need a T1 crossover cable.


If show interface pri 1 doesn't look like

.......................D

then you have a problem with the PRI setup, could be the PBX or configuration mismatch.

If both of those are good, then do debug isdn l2-f and post the results.

Re: Using TA908 as a PRI tester

I just spotted something that could be an issue, kind of subtle.



!
interface t1 0/3
  tdm-group 1 timeslots 1,24 speed 64
  no shutdown


This will only allow timeslots 1 and 24, so one bearer channel plus the driver.  Probably not what you want.

Try tdm-group 1 timeslots 1-24 speed 64 instead.

Thank you very much for your replies, I actually had it working for a short wile, however i didnt save my config and now it not working

Add in Role user on one of the units did the trick, D channel came up!  Again Thank you

I have my fist full IP PBX install coming up and the customer has an existing PRI so im trying to get a little fimaliar with the 908 as that is going to be my gateway of choce

When the PBX arrives im going to try to get a PRI to SIP setup going, and test it wuth my second 908.

Thank you very much
