[comp.dcom.telecom] Cynex call diverter

rshuford@well.UUCP (Richard S. Shuford) (12/22/87)

Greetings, netlanders.

A local nonprofit organization recently solicited my help in getting a
certain telephone accessory to function properly.  The device is a
"Remote Control Call Diverter", model CD-202, labeled as being made by

   Cynex Manufacturing Corporation
   28 Sager Pl.
   Hillside, NJ  07205

It was purchased by mail order through H&E Computronics.

This little gray box with a DTMF pad on top has inputs for two telephone
lines.  It is supposed to act as follows: When an incoming ring signal
is detected on line B, it dials a preprogrammed forwarding number
through line A.  Then the box connects line B to line A and someone who
answers the number dialed on A can talk to the original calling party. 
(It is not clear to me whether the diverter can be counted on to detect
answer supervision on line A.)  Conversely, calls coming in on line A
are forwarded out through line B. 

It has a remote-programming mode.  To use this, you place a call from a
remote location (with a DTMF-equipped phone) to line A.  You let it ring
once, then hang up.  Then, within 30 seconds, you place a second call to
line A.  The diverter answers line A, beeps and waits for a prearranged
DTMF security code.  Upon receiving the proper code, it goes into
remote-programming mode.  In this mode you can place the unit on
standby, change it from standby to active mode, or change the number to
which calls are forwarded. 

Well, that's all very nice, once you have figured it out from the rather
poor documentation.  And the procedure for remotely programming the thing
is rather tedious, but you can get used to it.

But the staff of the organization complains that the diverter unpredictably
goes into catatonia, placing BOTH lines off hook and not forwarding.  Or
it simply fails to forward, even when seemingly properly set up.

Does anyone have experience or advice concerning this or similar devices?
