Probably already been covered but you do have the power connector on the board connected right?

The docs > > ( http://www.intervoice.com/_docs/.433/601016.PDF ) I just ran some tests. The US FCC specs are:- Standing voltage = -48 VDC (minus) Ringing voltage = 85 - 105 VAC current supplied = 20 to 50mA (I haven't checked this as I would have to create a break and bridge with the digital multi-meter) My line from the central office Standing voltage = -51.1 VDC (minus) Ringing voltage = 90.7 VAC Port #1 Standing voltage = -48.4 VDC Ringing voltage = 42.7 VAC Port #2 Standing voltage = -48.2 VDC Ringing voltage = 42.7 VAC Port #4 Standing voltage = -44.4 VDC Ringing voltage = 43.5 VAC It looks like my card/modules, are not providing the required ring voltage. Anyone else checked their voltages ?
