CME overhead paging help (FXO/FXS)

[hunt3rxhunt3r]

I am trying to integrate our Muzak overhead paging system with our CME router. The paging system does NOT supply a dial tone. It just acts as an amplifier. Would I need an FXO or FXS port to connect to the system?. Could you please post a sample config that show's me how this is done.

It depends what type of interface your amp has. It can be FXS or FXO depending on the paging system.
Does it require a trunk port or a station port? That is how it is usually defined in the paging system manual. trunk port would be an FXO station port would be an FXS.

The amplifier is line level going into our system which will probably be a mono RCA jack so I’d say trunk port. Can you provide info on the configuration?

 

[whykap]

if it's line level into an RCA jack it's probably looking for a 600ohm input to the amp. Correct?
If so neither a FXS or FXO will do. You'll need a E&M module.
Either way you will need a ephone dn configured with the paging code as the dn and a dial-peer voice pots pointing to the E&M port.

Thanks for your responses.

Yes you are correct the amp is looking for a 600ohm input. Just to reiterate everything, we currently we use a PBX system which connects to the overhead paging system. The overhead paging amplifier uses a TOA L11s paging module as the input. We want to get rid of the PBX system and connect our CME to the TOA L11s paging module on the overhead paging amplifier. So an E&M port is the correct device to get?

 

[whykap]

for 600ohm output an E&M module is what you need.

Our paging system does not have an external push-to-talk control input. All is has is the audio input. When I asked our paging system support tech about this push-to-talk control input they responded with "it is initiated by a mute coming form a microphone or a phone system". Not really sure what they mean by that. The E&M port has 2 pins dedicated to Push-to-talk 7 and 8
Will not having a push-to-talk control effect the E&M from working properlly? Or can I just use it without using pin 7 and 8?

 

[whykap]

you will use 2 wire e&M not four wire.

 

[hunt3rxhunt3r]

2 wire by using the following command?

operation 2-wire

Nevermind on the last question, I was able to get the E&M port configured and working. Thanks for all the help, you were way more helpful then the muzak monkeys and cisco tech support robots.
