Fax server setup

[joeban]

Hello,
We have an option 81C and I have asked by the managment to get a quote for aT1/PRI brooktrout fax card. My question is that from your experience what is a working solution for this king of setup?. The card type needed. The software that is running on your server. I will be integrating the fax server on an internaly PRI card. any hints or a how this can be done will be greatly appreciated.Thanks for your help.
Joe

I have an 81c and we used 2 brooktrout TR114P8V-T1 cards.Each card has 8 port capacity.I built the T-1's in the PBX on QPC720 cards.The idea is if one brooktrout card fails or gets the 9th call it will hunt over to the next card.It seemed like a waste to me though because you need 2 QPC720 cards/2 network ports,all the cables and then you only program 8 voice ports on each T-1.we experienced some problems with the cable pin-out config.from the 81c T-1 card to the brooktrout server.We ended up using standard cables and used a rj-45 harmonica to connect all the pins correctly-then pluged in on one port and out to the server on the other.Also we we built our main fax # as a cdp dsc and it was returning busy signals and producing false errors on the 81c terminal.After calling our vendor's engineering dept. We found out that it was a known problem with nortel for internal T-1's with cdp dsc being used.It corrupted our switch and we re-loaded it early the next morning and Bam! it all worked and has worked great since.Let me know if you have problems with anything and I will try to help.

Thanks jimeec,
What type of software are you using on the faxserver "manufacturer" so we make sure we have a good tech support.Are you using your t1 as T1 or PRI?. Is there a card that handale 24 channels. Any place I can go to see how all this are programmed from the PBX side.
Thanks for your help

I have a definity G3r V111 a TN464F Circuit pack with 120a3 CSU. I created a Tie Trunk group as specified by the BrookTrout support. This Tie Trunk will serve as a T1 to this BrookTrout card which has been installed into a fax server.

Here is a diagram:
<->PBX--TN464F--CSU--CABLE--BROOKTROUT T1034--FAX SERVER<->

I have been questioning the cable. I've tried both straight and crossed. But i'm still unsure.

When I status the trunk group it tells me my members are active and ready.

I've double checked the trunk and DS1 settings.

I've tried three differnt TN464f cards and two CSUs.

How can I prove what is working and what is not?

Any and all help will be greatly appreciated.

Is there anything on the brooktrout card or fax server that needs to be considered or applied when setting this up or testing for the first time?

I can help you if you have a definity G3r. What do you need to know?

Snapper:
I have almost the same setup: Definity G3si v11, and I'm building a fax server using the older TR114+P8V and TR114+P16V cards. I have PRI lines coming into my phone switch and would like to send a subset of my DIDs (all odd numbers) to the fax server. I assume I can make a tie trunk like you did using a TN464F DS1 card, but how did you send specific DIDs down that trunk?

Thanks!
Josh

 

[Snapper]

In my case I have to build it backwards:
1. you've created a trunk group right? Add a route patern with this trunk group number and delete 3 digits.(a)

2. Find the next available &quot;route index&quot; inside your Partition-route-table and assign it the route patern (a) you just created his will be (b).

3. Find an avaialble 3 digit udp code and then say change &quot;AAR analysis&quot; whatever udp code you found. insert this code in the next available field. Min and MAx didgits =7, Route patern=(b), Call type=aar

4. You already know what ext number you are using so lets say 3990 to 3999 OK. Say change uniform dial plan 399. In the next available matching patern field enter 399. Lenth=4, del=0, insert digits= 3 digit udp code you created, net= aar.

so every phone number from 3990 to 3999 will automatically route into the trunk group you created.

Hope this helps. If I can be of any more help let me know. Good Luck.

That sounds like it would work for blocks of numbers. Was I stupid to promise every odd number? If I want to make this happen, do I have to add each DID separately? Or is it easier to have the telco port the numbers down a separate PRI?

 

[Snapper]

Yeah odd numbers was probably not the best choice. You will have to either change your promise and offer blocks of numbers or program each idividual odd number or pay and rely on the telco services. I don't like the idea of depending on the telco, they are so unreliable and expensive. Besides if you choose telco you become less valuble and you will have to take the rap for their screw ups.

OK so I ordered a new block of DIDs. Your instructions make sense for inbound, but how does the switch grab a channel for outbound calls? Is that COR issue where I tell any outbound traffic on the tie trunk to grab a channel in a PRI trunk group?

Josh

 

[Snapper]

As far as outbound you don't have much to do. If your trunk is configured right and the FRL values are right your good to go. I remember it did not work for me The first time. I had to change the FRL values in the CORs to make outbound calls. It's not a big deal. Just read up on it a little and compare the FRLs with other trunks and CORs.

Thanks, Snapper! I'll let you know how it goes next week when I receive the hardware I bought on eBay!

Snapper,
I followed the directions on Brooktrout's site to configure my tie trunk, but when I status the trunk it says out-of-service. I have no green light on the brooktrout board either. Is there anything I have to do to activate the tie trunk? All I did was add a DS1 and add trunk group 7.

Thanks,
Josh

 

[Snapper]

Try Busy Board XXXXX, then release board XXXXx. Then status the trunk. All memebers in that trunk should be in-service. When I setup mine It did not work either. I found an error in the BrookTrout configuration for the DS1 part. I had to change the framing mode to &quot;esf&quot; and the line coding to &quot;B8zs&quot;.

Attitude is everthing.

[jrobs]

OK, I actually changed the member to 02A1624 instead of 02A1601 and now I get in-service/idle. However there's no green light on the brooktrout board.
First things first,
I'm trying to follow your directions for routing inbound calls over that tie trunk using AAR and UDP, but I'm fumbling... I want to route all DIDs in a block of 100, from 5300-5399 (full number is 312-491-5300). So do I delete 2 digits?

Here's what i did:
1. Created trunk group 7 as a tie trunk, robbed bit t1 per brooktrout's docs.
2. Added route pattern 7 with trunk group 7 as follows:
Grp 7, FRL 0, NPA 312, Pfx Mark 1, No Del Dgts 2

3. The next available index in my partition route table was 3. I put 7 in the box.

4. I did &quot;change aar analysis 53&quot; and filled it out:
Dialed String: 53
Min: 7
Max: 7
Route Pattern: 3
Type: aar



5. I did &quot;ch unif 53&quot; and entered:
Matching Pattern: 53
Len: 4
Del: 0
Insert digits: 53
Net: aar
Conv: n

6. Now to test I created a station 5350 on the switch and programmed a regular phone, and when i dial from outside the phone rings, which means it's not routing that block down the tie trunk to my fax server!

Thanks a lot!
Josh

 

[Snapper]

You are not supposed &quot;create&quot; an station. Once you've administer the udp/aar etc thats it, it's been created. In the route pattern form leave NPA blank and Pfx Mrk Blank. Check that DS1 stuff try changing the framing mode to &quot;esf&quot; and the line coding to &quot;B8zs&quot;.

Snapper,
I got the inbound calls to route down the tie trunk, so thanks for your help!

Now when I dial into one of the fax DIDs and status my trunk, I see first 1 channel goes to active, then 2 channels, then the second one only, and finally I get a fast busy signal. Meanwhile i get no activity on the Faxmaker monitor. My TR114 doesn't have a green light, it only has a solid yellow and a solid red. I set the DS1 to B8ZS and ESF, and set the jumpers accordingly on the TR114+P8V-T1.

I've tried a regular cat 5 patch cable and a crossover cable, but nothing seems to work. Which are you using?

 

[Snapper]

I'm using the Avaya standard H-600-383 CSU to Network patch cable. I pretty sure it a straight cable.
Instead of doing a status trunk try,list trace TAC &quot;XXX&quot; TAC = trunk access code. This is the code you assigned the trunk when you first programed it. You can see the activity as it happens.
The light should be green if your protocols are right and if the cable is good. I think if you see yellow the protocals are wrong. Are you using a CSU?

Attitude is everthing.
-Snapper

 

[jrobs]

Yea! I made my own cable with pins 1&2 crossing to 4&5, like the avaya cable pinouts. Now I have a green light!

However I can't get the trunk group to get out of the in service/active state, and it doesn't say it's connected to any port. I've busied it out and released it many times...

When i do List trace TAC 111 it hangs for a while and finally closes my ASA session.
any ideas?

thanks for all your help!
Josh

 

[Snapper]

Try busy board &quot;xxxxx&quot; the release board &quot;xxxxx&quot; Your board number should be something like 03c19. Then status your trunk. When you do the trace command there needs to be some kind of activity or else it times out. Try sending out too.
You are doing it dude!
