Magix R1.0 w/100 R INA, 800 DID, 016 T/R, 412 TDL

Current environment:

1 Integrated T1 - voice & IP
3 Analog 2way ground start trunks
3 Analog DID wink trunks

Here's the proposed service environment and questions (which, naturally, we can't answer):

All services replaced with Qwest OneFlex Integrated Access VoIP PRI (w/ local voice, long distance voice & dynamic IP).

The Integrated Access Device (IAD) Qwest provides needs to know if the hand off to the PBX needs to be T1 or analog for the voice channels – but of great import to us is to have DID and Caller ID, so our equipment apparently has to be capable of PRI interface... ? is it? Do we have the correct release and/or modules to finally have Caller ID? ?

Qwest provides a Call Screening Number a PBX can override - do we have the appropriate equipment and most importantly, release version to do so? ?
 
The 412 cards will not hanle ground start trunks, nust as a note. Your 100R card is a DS1 interface, and can be configured to handle PRI. If all the services are going to come through Quest, then the DID card can be dropped. Make sure that you leav some local trunks on the system for a fail over situation, and for 911 calls. I'd ve very curious about the quality of your voice services on such a setup.

Thanks for the response, Pepperz. Our current 2-way trunks are ground start and terminate into the 412 TDL – so am I goofing up where these 2-ways terminate? Because it works fine… but maybe it doesn’t work the way it’s s’posed to?

And yes, Qwest will deliver all the lines using a Cisco 1760V IAD to split off the voice traffic from the Ethernet. We will keep POTS lines for emergency/faxing. The quality of voice services has been addressed by Qwest thusly – they use QoS to prioritize the voice packets to create streaming voice which should stave off the choppiness that you can sometimes experience with VoIP.

Thanks oodles,

Annie, if you have the groundstart trunks going into a 412, they will answer, but won't make calls. If you're able to make calls on the 412 card, they aren't ground start.

Thank you sooo much for your interest and responses - I've opened a trouble ticket with Qwest to confirm loop start vs ground start config on the 2way analog trunks... will let you know what the Qwest Tech ascertains.

But it's entirely within the realm of possibility that I'm reading the 412 module info incorrectly - it says 412 TDL LS-ID 617E34A
And it's possible that the Qwest info is incorrect and altho they're billing us for ground start, the trunk are actually configured as loop start...

Thanks again..
 
Acid test: Take a "Kmart" phone (regular household analog) and plug onto each of the CO trunks as they come onto the 412 card. If you can get dialtone, they are not groundstart.

took a regular analog phone and plugged it into each of the five RJ11 openings - and got no dial tone.
Qwest tech came out and said "these are definitely groundstart trunks" but couldn't say if those trunks were connected to our 412 card.

It almost appears that there is no telephone lines terminating on that card - it's got a big old cable (as in a computer cable) that is attached but that's about all.

A 412 card has the top 4 ports to take 4 telephone lines that terminate on a modular telephone plug. The bottom connector is an amphenol connector that supports the 12 TDL extensions on that card. If you check the lines, do it just "upstream" from where they come into these RJ-11 ports. The ports on the card will give nothing if you plug into them. It sounds like there are no Telco lines coming onto that particular 412 card.

hmmm... upstream doesn't afford any other opportunity to "plug in"... unless I had a nifty test set...
 
If there are lines coming into the 412 module, they will terminate in an RJ-11 plug which will fit directly into the K-mart phone.

::banging head against desk::
ok, you MUST be right because there is no rj11 plug to be found... so are we only using this module to communicate with the 12 stations?
 
You sure the module is not an 024 TDL?

The five RJ11 openings are where the lines go into the card. You'll find the dial tone on the plug that goes into it. You'll need to put that pluf into the socket of the single line test phone, or use a cord coupler to attach to the line cord of the test phone. BTW, the 5th RJ11 up is the power failure jack, where you would connect a single line phone to receive dial tone during a power failure.

That "big old cable" is carrying the stations out to a terminal block or patch panel or what have you.
