Billing pulses
Hello,
I've discovered that in Italy ISDN lines can be
programmed to generate a "billing pulse" every n
seconds (it dipends from the pricebook). The pulse has these figures:
frequency
....................................................................
12 kHz ? 1%
level
..........................................................................
200 mVrms on 200
distortion.................................................................
