How to link two MICS together for single phone.

[iPepsi57]

I am incredibly new to this forum. I looked through some older and more recent posts. I am hoping that there is still help out there as most other forums are dead.


I have been assigned a task to get our MICS 7.1 to connect to another building across the street with the same system.

The task is the other building can press a button to call our phone system (a single extension on an analog port) to trigger our intercom via a phone ring.


Basically, the mics we have in my current building has an analog port with an extension, that when called, will ring a circuit that I built to trigger an intercom using relays. The intercom will then make an announcement, all thanks to the ring voltage generated by the phone lines.

I want to connect the building across the street, not so they can talk to each other, but so they can utilize this system and trigger the intercom the same way. (as our intercom is SIP and VoIP speakers).

Would this be possible with CAT 6 or CAT 5e? I already have CAT pulled to each site.

Thanks in advance.

More splaning Lucy!

1. Can you confirm when you say "Intercom" do you in fact mean "Page"?
Intercom - to call another device/phone internally
Page - to make an announcement over speakers/phones

2. And that you want the set or a button at site B to page the speakers overhead at site A?

3. What type of link/cable is between the 2 buildings?
4. How far is it to run a cable if can?

5. What paging amp is currently used at Site A?

The intercom system is a Nyquist. It is in fact an intercom and paging system/

The Nortel will not be doing any paging at all. The sole purpose of us using the Nortel is to just trigger the intercom system to page. We are using an input/output controller to detect a phone ring through a circuit I built that will close a relay to initiate the paging function of the Nyquist.

I probably shouldn't have brought the intercom in the equation as that just makes things more complicated. Lol, sorry about that.


As far as a button goes, the Nortel is doing all of the work.

We have an extension setup to an analog port, that when called, ring voltage will trigger a relay that triggers our intercom. Basically, the nortel doesn't know that it's not a phone. This already works at our current site, let's call it Site A.

Site B also is a Nortel MICS 7.1. It does not have any analog ports, but it has an ATA2. I have CAT 5e running from our building - Site A - to theirs - Site B. It is about ~200ft away.

What we are wanting to do is, use the ATA2 at Site B over CAT 5e to carry an analog phone ring tone/voltage over to Site A to trigger our little circuit to close a relay (using the ring voltage/tone generated by the Nortel)

That solution would require no programming at all, but our other option would be to tie the two Nortels together so we can call them with an extension instead of dialing their phone numbers and being transferred. Again, we just have CAT 5e and CAT 6 running to that building. This is not required. It was just a suggestion. My task was to just get their Nortel system (Site B) to trigger our relay circuit at Site A, which LOOKS as though it can be done with just an ATA2 and over CAT 5e or 6.

However, if I can get the two Nortels tied together so they can just call any extension at either Site A or Site B that would be the preferred method.


Thank you!

That part is easy, the rest is still confusing because of being unsure of what exactly you are doing with this Nyquist, why is it even on site? to trigger a relay but for what?

Assuming very low volume of calling:
Required - 2 ATA's and 2 spare Trunk ports

If just for Relay purpose:
Site A_____________________Site B
ATA X300 <-------------------->Trunk Line 034 - Site A dials 300 to reach site B
Trunk Line034<-------------------5>ATA X300 - Site B dials 300 to reach site A
Now depending how each side is to answer you have to methods.
-Assign trunk port to Appear & Ring at the reception set, do same for both sites.
Above is for 1 communication path each way.

If just to intercom sets:
Site A_______________________Site B
ATA X300 <-------------->Trunk Line 034 - Site B dials 8 to reach site A
Trunk Line034<--------------5>ATA X300 - Site A dials 8 to reach site B
On each site: Build Dest Codes 8 to use Route 008, Route 008 to use Pool C - Trunk Line 034 is in Pool C

Now depending how each side is to answer you have to methods.
-Assign trunk port to Appear & Ring at the reception set, do same for both sites.
or
-Assign AA to answer Line 034

Other ways:
Gateways
2 DTI/T1 cards
E&M Cards

Thanks @Curlycord.

Again, I am not sure why I even brought the intercom in the equation. The intercom system is a Nyquist. The relay triggers the intercom to page an alarm sound when it is closed. The Nortel closes the relay, which in turn triggers the intercom to page an alarm over all of our ceiling speakers.

The purpose of the whole setup is for a panic alarm using one button. The easiest solution to this task was to use the phones (and cheapest) to achieve our goals.

As far as the calling between Nortel MICS. Thank you. That was really helpful.

I'll just use two ATA2's.

That will give us only one pathway, but that's fine. I'm sure they will rarely use it to talk since it's purpose will be to ring the phone at Site A from Site B. Again, the ringing of the phone is what triggers the relay.

That is exactly what I was after, thanks.

My above example is for one way each way.
So if somebody at Site A calls somebody at Site B then the same can be done in reverse, meaning to calls only allow (1 each way).

You need one Trunk and one ATA, not 2 ATA's....ATA's cannot call each other in this scenario.

But if just needing for a relay:
Site A_______________________Site B
ATA X300 <-------------->Trunk Line 034 - Site B dials 8 to reach site A
On each site: Build Dest Codes 8 to use Route 008, Route 008 to use Pool C - Trunk Line 034 is in Pool C


But most Bogen paging devices would allow for a Trunk port to be used instead of the page port...

Site A_______________________Site B
Relay port <-------------->Trunk Line 034 - Site B dials 8 to activate page.
On each site: Build Dest Codes 8 to use Route 008, Route 008 to use Pool C - Trunk Line 034 is in Pool C
Program buttons on sets as External 9300

The Nyquist system we have is a Bogen E7000. It has SIP trunks.


Again, I shouldn't have even brought the intercom in the equation..

Essentially my task was to get the two Nortels to talk to each other.

We have four outbound lines on Pool C, also.

 

[curlycord]

Pool C, Line 034, X300 etc..it's all an example so use what ever you want.

Said another way,

An ATA is connected at SITE B and therefore has an extension
The output of the ATA is run across to SITE A and into a free analog trunk port there
That truck (set to public) is assigned to ring on the current ATA at SITE A that triggers the device/paging

Users at SITE B dial the extension of the ATA at their site and trigger the device at SITE A.
