Reverse Battery operation
When the CO trunk returns a Reverse Battery (RVB) signal, only one pulse
is received for each outgoing call. This pulse is passed to the software meter
for storage. The meter is incremented once for each metered local call
regardless of duration. Reversals received within 2 seconds of digit
outpulsing completion are ignored.
