atcomsystems.ca/forum Forums TDM Business Telephone Systems Toshiba Telephones & Systems DK-280 & ISDN integrated PRI - HELP!!!

I'm losing what's left of my mind here....

Client has an upgraded DK-280 running version 4.3, a BPTU PRI interface & the carrier; Conversant (...or whatever they're called today...) is trying to implement an integrated PRI.
They're using an Adtran "Total Access 600 Series" integrated access device with a DSX-1 port.
The first 13 channels are for Internet access, the next 10 channels are for D.I.D. voice traffic via the DSX-1 port & plugged into the BPTU in the switch and channel 24 is the "D" channel.
I've got a bunch of "traditional" ISDN PRI installs under my belt, with the very same DK-280 configuration, but have no practical experience with this Conversant integrated solution. And so for, it has not been a good experience.
The carrier cannot see the "D" channel from the BPTU. We've replaced the BPTU thinking it was suspect, ...no go.

Has anyone out here got any practical experience with this type of configuration that could possibly shed some light here???

Thanks!

how many B channels do you have??

If you want X channels of bandwidth and X channels of PRI, you use an Adtran 3200 with a DSX-1 port.

I've never seen an Adtran 600 series that does PRI. An Adtran 624 is a channel bank that gives you 24 analog lines.

They have 604s and 616s that are partial analog lines and bandwidth.

Were I you, I would call Adtran tech support at 1-888-423-8726 (NO caller ID blocking allowed-no help at all-no call back) and give them the model number of the Adtran equipment you have on site.

I betcha Conversant is all screwed up. I betcha.

LOL, ....and it wouldn't be the first time I've been foiled by Conversant!
In any event, I've been researching the Adtran unit & I too suspect something is amiss there.... You’re correct in your assessment of the 600 series. It doesn’t appear to support PRI. While the 904 series does….
I have an acquaintance at Adtran that's the region's sales support guru. I'll need to run this up his flagpole too....

We have several sites where bandwidth comes into the Adtran 3200 and X number of PRI channels and the D channel come out the DSX-1 port and bandwidth flows out a second port.

This works flawlessly once programmed.

Not know which 600 series unit you have makes it impossible to research but if it has a DSX-1 port, it may support T-1 and not PRI.

The model number you have and a brief call to Adtran will confirm everything. I would call in to Adtran while on site and if the unit is able to give PRI, the Adtran technicians are the best I have seen from any company bar none and they will have you up and running. At least you will know the certain truth, this is the best of the best tech support.

Steve, looks like Conversant is handing off 10 or 12 B channels for D.I.D. to me.

If you only have 12B channels, wouldn't your D channel be 13?

That's the rub. I need to learn if they're handing me their channels 13 - 23 as my channels 1 - 12 with my channel 13 as the "D". ...apparently, I now need to be an Adtran guru too! ;-)

If they said that the d channel is on the 24th, then I'd would set the BPTU for the same. What slot do you have the BPTU in and what code in prog 03 did you assign the BPTU?

To answer your question on whether the Adtran 600 is PRI capable, I'm looking at an Adtran 600R right now with integrated data and PRI that's working on a Toshiba CIX. The first 8 channels are for voice with the d channel on 24.
