The
CPC-4
has four independent chan-
nels of CPC generation. Each channel will
generate a CPC disconnect signal on a
PABX analog station (or any other line that
does not provide this signal).
A
CPC
(Calling Party Control) signal is a
momentary break in phone line loop cur-
rent, which is used to signal automated
telco equipment (ie. voice mail, call
sequencers, etc.) the distant party has
hung up. Central Office telephone lines
typically provide this signal, but Analog PABX stations do not.
The
CPC-4
will generate a 1 second disconnect when it detects a busy signal, reorder
tones (fast busy), return to dial tone, or silence.
