Networking key system and PBX 1

[ljclives]

I just received an opportunity to bid a new Norstar Compact ICS. The cust. wants to install a T1 between one of thier other locations(OPT 61C PBX) and use extension dialing between the two. The specs call for a LS/DS trunk cartridge at the CICS with two of the trunks being used for connection between the locations.
An Adtran TSU 100 with FXO and FXS is called for at each location. Please give me an overview of what I need to do with the CICS and programming. Also, how are the FXO and FXS used and a how does it connect to the Norstar. Thanks.

Is there anybody out there?

I'm trying to figure out and understand the application in your thread. It doesn't make sense that a T-1 would be installed between the locations for 2 Ports on an LS/DS card. What about the remaining 22 channels? It sounds like they want to extend 2 analog ports (extensions) off the Opt 61 and send them accross the T-1 on the Adtran TSU100 via the FXO/FXS interface and connected the 2 extensions to the CICS on an LD/DS card. From the CICS you could access one of the Extensions and basically dial any extension or access code on the OPT 61. Or from the OPT you could dial those Analog Exts. and ring in on the LS/DS card on the CICS. That's the only thing that I can figure out and it's a bad design at best. They need a MICS with a T-1 card and connect the T-1 switch to switch.
Do you have a part number for the Adtran TSU100? I'm on the web site and this thing comes in many flavors and I'm trying to located the one with the FXS/FXO capabilities?
Do you have a "Scope of Work" or anything that let's you know the thoughts behind the application?

the method that norstar is suggesting for their VOIP Gateway is to use LS/DS ports on a CICS with autoanswer/DNIS in use.

the installer would then program a destination/route to dial the number to the LS/DS port then after autoanswer dial the extension number. Like stated it is a way that, while not an integrated solution, does allow an integrated dialing plan.

Thanks for the response as I haven't worked with the VOIP Gateway as of yet but this is very good information. How would the Adtran be used with the VOIP Gateway in this application?

 

[jerryreeve]

The VOIP Gateway is used over an existing net, prefered private network, and one VOIP Gateway would exist on each end plugged into the nework.

I havent used the adtran that much but I would expect to see the adtran just dropping an analog channel out of the T1 stream, like Treba said above (sorry for stepping on you) the option 61 could then either use a trunk or just an analog extension, depending on how the 61 will be programmed. you would have to coordinate witht he 61's tech on that.

Hello trabra,
Thanks for the response. This cust. has done this with their other locations so it is something that does work.
The T1 is going going to have voice and data channels; not sure of the exact split at this time. They definitely want extension dialing between the CICS I will be installing and the Opt. 51C (not 61C) at their main location.
1) Does the 51C tech connect two analog ports into the adtran? What is the difference between the FXO and FXS on the adtran?
2) Will I just be receiving "analog" dt on the FXO/FXS on my end to connect to my two ports on the LS/DS?
3) Where can I get some good insight on programming the CICS on my end to allow extension dialing between the two locations?
I serviced the Norstar and Opt 11-81 for 8 years but have never done anything like this. Any help appreciatted!

1) Does the 51C tech connect two analog ports into the adtran? What is the difference between the FXO and FXS on the adtran? FXO/FXS is channel bank terminology and FXO is the Trunk side and FXS is the Line Side. Yes, the 51C tech would connect two analog ports into the Adtran!
2) Will I just be receiving "analog" dt on the FXO/FXS on my end to connect to my two ports on the LS/DS? The 51C tech would connect two anlaog lines to the FXO Ports of the Adtran and you would pick up the 2 analog lines off the FXS port on the CICS side. And yes your just getting 2 loop start analog extension off the PBX to install on the CICS. From the CICS side, you will have extension dialing toward the PBX but on the PBX side you won't be able to dial up extensions, but just ring in on the CO port.
3) Where can I get some good insight on programming the CICS on my end to allow extension dialing between the two locations? Do you have the CICS manuals? Beyond that I would talk to the vendor who installed the other system that is working and get the details from them. Again, in my opinion this is a very week design and if this is what they have at the other location you may be able to show them a much better way by proposing a MICS with a T-1 directly into the PBX and then they would have transparent dialing between both locations. Just a thought!

All that is needed is either a T-1 or a PRI circuit between the two sites. The option 51 and the CICS are both Nortel products and are compatible.As long as both ends of the circuit are configured EXACTLY the same there will be no problem. Program both switches with CDP and away you go.No other equipment should be needed. I've done this a few times before.

BerettaMan:

How did you connect a T-1 into a CICS? If the customer goes with the MICS then your correct but from what I have read they have an existing site connected to the Option 51 and a CICS through an Adtran TSU100. Just curious?
