Paging system - page length

[trvlr1]

We have a Valcom V9940 and Valcom paging system interfacing with a Nortel PBX, to an analog port. This station level page adapter has limits on the length of a page denoted by internal switches to a maximum of 64 seconds. Does anyone know if there is a way to set this up for longer pages or if there is an aditional piece of equipment that would allow a longer page message time, that we could use in parallel from another number?

If you use a standard zone page adapter like from Gordon Kapes it ties right into a trunk on the PBX and outputs to any standard overhead paging amplifier. You would need an open trunk port and the programming to set up a trunk group for paging, define the paging trunk itself, and create the dialing string and permissions used to access it. That's what we do in all our facilities. We have 4 codes built into our dial plan for a variety of paging applications 80, 81, 82 and 83. You dial the appropriate code and receive either a "select a zone" tone or a "ready for page" kind of tone, and after that you can pretty much talk until you hang up.

It looks like the 9940 supports a couple of styles of disconnect supervision. Have you read the install manual (found at

http://www.valcom.com)?

In theory you can deactivate the timer if your system supports one of the other disconnect methods. OR as donb01 suggests, use a trunk level interface instead of station level.

Thanks donb01 I will check that out.

Thanks mforrence I have read the manual we got with the system but it did not help too much, it stated you could add all the times together (64+32+16 etc) to get a longer time too, but that would not work at all, it just reacted to the first switch timer it saw, ie 4 seconds. Trying to get it to cut off after silence for x seconds, just busied out the lines completely. The longest we could get it for any configuration we tried was 64 seconds.

it looks like you can set switch 1 off instead of on and you will have a vox setup? check with the tech support from valcom, they can help you on lunderstanding the manual best next easiest way to bypass this it looks like is use something like a

or a

and then use the vox control to sense when the paging is in effect and feed this thru the music input to the PA Amp. the music is alwayse on so you don't have to worry about that pesky timeout issue.

I talked with the Valcom techs, whatever we tried did not work.
Does anyone have this set up using a Nortel trunk instead of an analog line? If so can you post your trunk settings please?

Saying Nortel is like saying Ford - covers a lot of territory. That said, there is no real magic to setting up analog trunk-level paging. Trunk needs to be loop start with either a direct line appearance or dial access on all appropriate phones. Page interface must be provisioned to match (usually providing the talk-battery). You won't have issues with page length. Good luck!
