[cisco-voip] FXS Ring Voltage

[Jack Martin]

Please disregard.   This explains why I wasn't reading 90V on the voltmeter:

"I found I had programmed the night ring to a zone that had a broken wire and wasn't working. I do believe flipping the tip and ring wires worked when you were here also.
Everything is working fine now."

Thanks everyone!

I guess the problem is that I am not seeing the 90V ring voltage??  Yes I'm calling the port.  I've tested inbound/outbound dialing with a butt set.

The night Ringer on the Bogen PCM2000 is triggered by either 90V on the tip/ring or contact closure.  I'm not sure what contact closure is so I'll run with the 90V configuration ;)

Craig, either you have some voodoo magic or I have a bad FXS card.

Wes, I'll look into the Viking line booster.

Thanks all for your help.

If memory serves, I think the night ringer port on the PCM2000 can be configured a couple different ways - contact closure, etc. As long as it is set for regular 90V ring, then you don't need anything special. Sounds like you already have it set up right, you just forgot to actually place a call to the FXS port. It's only going to provide ring voltage when someone's calling it. I like to put the FXS port's DN in a broadcast hunt group with the reception phones, with time-of-day partitions to achieve the "night" portion of the night ringer.

I have a customer that wants to connect a FXS port to a Night Ringer on a Bogen PCM2000.  We are seeing the 48V on the circuit but we need 90V to trigger the Night Ringer.  Do we use a step-up transformer in this case or does anyone know of a 3rd party solution?

Thanks for your help.
