I've tried searching the web this afternoon and all I have available are software manuals locally. Can you gentleman tell me what the idle and ringing voltages are on a CS1000 ring generator card please?

We have a vendor that wants to know if a piece of analog equipment they want to install will be suitable based on the voltage supplied.

Device will be installed on an analog MW line card, Ring Generator is an NT6D42CD. We have measured 13.5v idle and 70v ringing, but I'd like to be sure.


Thanks for your assistance.
I was given an answer, for anyone else who searches.

Idle- 48VDC
Talk- 24VDC
Ring- 90-105VDC
