Hey Mike,<br><br>I just wanted to clarify that the standard ring voltage that you should receive from the telco is 90Volts AC. Not 150 VAC<br><br>This is also what Cisco FXS ports output as ring voltage.<br><br>Craig<br>

Correct, traditionally night ringers connect right onto an FXS port.<br>
<br>
Base line voltage on an FXS is -48 volts DC. Ring voltage is 150 volts AC.<br>
When it rings, it will trigger a night ring input (like the input on a bogen<br>
amp for example) to play its ring tone over the speakers.<br>

Sorry. No, I used the FXO for paging. However it sounds like the night bell<br>
is supposed to be activated when the phone rings.<br>
<br>
via Wikipedia...<br>
<br>
<br>
The ringing signal sent to a customer's telephone is AC at 90 volts and 20<br>
hertz in North America.<br>

You used an FXO port for the Night Ringer?<br>

If you have an FXO card/port, use that instead. It works like a charm on the<br>
PCM 2000...'er it did for me off of a 3825 box with an FXO card on it.<br>
<br>

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