The CP-1 and CP-2 are call progress
decoders that allow any automatic telephone coupling device to hang up properly
on PBX or other telephone lines that don't provide the customary end of call D.C.
signaling, commonly known as CPC or COD. Many PBXs and a few telco COs do not provide
the end-of-call drop in line current that makes telephone couplers hang up. So,
the CP-1 and CP-2 listen for dial tone and/or busy (reorder) signals and force the
attached unit to hang-up if they are detected.
The CP-1 is designed to fit inside other CircuitWerkes products such as the DR-10,
HC-3, or AC-1.
The CP-2 is designed to be used with all telephone devices, regardless of maker.
Installation is simple: Just connect one RJ-11 to the wall and the other to the
device that you want to hang up.
Both the CP-1 and CP-2 feature internal jumpers that let you select whether they
will detect dial tone, busy or all tones. User adjustable delay before hang up prevents
false tripping.
