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. |
