[Asterisk-Users] Ring Voltage Supplied by Wildcard TDM400P REV E/F & AUTO FXS/DPO

[Timothy Costello]

Hi;

I'm trying to connect a TDM400P with an FXS module to a Valcom V-9940 
Paging adaptor. This port on the TDM400P was connected to a 2500 Set 
and was working I just re-connected it to the Valcom (which is known to 
work on a Telco POTS line) and its not picking up.  The Valcom docs say 
it need a minimum of 75 Volts at 20-30 Hz to recognize a call... So the 
question is what ring voltage does the FXS modules on a TDM400P put 
out?

Thanks;
Tim
