A. Generating a CPC Disconnect
The CPC-1 monitors audio activity on the line to determine when to generate a CPC disconnect signal. A CPC dis-
connect signal is generated if busy signal cadence, or a reorder tone (fast busy) cadence is detected. Using DIP
switches 1 & 2, the CPC-1 can also be programmed to generate a CPC disconnect signal based on uninterrupted
silence. The CPC-1 will not respond to originating Dial Tone, but can be programmed to generate a CPC disconnect
signal if the line returns to Dial Tone (steady audio).
B. LED Operation
The CPC-1 is in use when the LED is on. The LED will light extra bright when audio is detected. For example, a busy
signal can be seen as the LED toggling between "on" and "extra bright" in a 1/2 second pattern. Steady silence shows
as steady on, dial tone shows as steady extra bright, and talking shows a random pattern.
The LED will wink "off" for 1 second when the unit generates a CPC disconnect signal. The LED will then remain off
when the line is cleared and not in use.
