The CPC-1 will generate a CPC disconnect signal on a
PABX analog station (or any other line that does not pro-
vide this signal).
A CPC (Calling Party Control) signal is a momentary
break in phone line loop current, 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-1 will generate a 1 second disconnect when it
detects a busy signal, reorder tones (fast busy), return to
dial tone, or silence.
