[cisco-voip] overhead paging system integration-UPDATE

Tue Aug 2 10:30:12 EDT 2005

I checked my paging setup. I have Valcom V9970s in place. There is an
RJ11 port to connect to the ATA port. The other screw terminals are for
connecting DC power and the speaker outputs. I have the DIP switches in
the following positions

1-OFF
2-ON
3-OFF
4-OFF
5-OFF
6-OFF
7-OFF
8-ON

I do remember at another site we had to adjust one of the other switches
that controls disconnect timing (? I think DIP# 4 or 5)

As I said before these units have been working great for some time now
connected to ATA186s. When you call the phantom # assigned to the ATA,
the Valcom unit answers and gives you a tone to begin talking.

If you have any other questions, please let me know.

We would like to know more about the setup using the ATA186 and a Valcom
paging unit. Can you please provide the Valcom model number and any
setup details you care to share.

Thanks,

	Mark,

	    I have several sites with overhead paging systems. I have
linked them to CCM using an ATA186 hooked to a Valcom paging adaptor
(the exact model number I cannot remember right now). I just put a
phantom DN on the ATA and program a speed dial on all phones that need
access. They press the speed dial and are greeted almost immediately by
the Valcom "talk tone". The paticular model I am using has feedback
reduction. I highly recommend using a phantom number, because if someone
on the outside dials into it you could have a problem. This has been
working perfectly for the last couple of years. I tried to use an FXS
port on a 3725 once, but I had problems with the port not disconnecting
properly and getting hung up. I switched to the ATAs and have had no
more problems. If you would like I can get the Valcom model number I am
using, just let me know. Hope this helps!

	Jason

	After having exhausted all my normal avenues of research
(including
	TAC), I thought perhaps someone here has run into the same
problem I'm
	currently tackling.  I have a site recently migrated to CCM from
an
	older Siemens PBX.  The site has a custom overhead paging system
that is
	as simple as can be imagined -- tip and ring link to speakers
and when
	this is connected to with the old system, voice is transmitted
over the
	paging system.  We initially thought we could just link to an
ATA-186 or
	an FXS port, but this thing looks like it is off-hook
constantly, so you
	can't only do that.  I also tried to put a Valcom V-9940 Paging
Adapter
	in the middle, but my layer 1 skills are limited and the
solution failed
	(I may have selected the wrong wiring configuration).  My
question to
	the list is, has anyone come up with a method to link CCM into
overhead
	paging systems, and if so, would you be willing to share your
solution?

	Thank you,
	Mark
