[comp.dcom.modems] Call Waiting feature on C&P region telephones

forman@ceee-sed.UUCP.UUCP (02/13/87)

I often use my home modem to call my office computer.  I have "call 
waiting" on my home phone in Potomac, MD, an area served by the Chesapeake
and Potomac Telephone Co.  
The "call waiting" feature appears to act like a 2 line hold button at the 
telephone company switching office. That is: my call is interrupted by a short
beep; I can then depress the receiver button and switch to the new incoming
call; the original call is placed on hold and can be retrieved by a second
depression of the receiver button.  The PROBLEM is that the short "notification"
beep disconnects the modem.
I am told that in other parts of the country the telephone company equipment
allows for the turning off of the "call waiting" feature by dialing out and using
some code sequence. C&P Telephone insists that there equipment does not have this 
capability.  THEY MAY NOT KNOW OR MAY NOT BE TELLINMG THE TRUTH.

Short of giving up the "call waiting" service, and without dedicating another
telephone line at my home solely for modem work what can I do.

Easy--just call forward your line to something innocuous like a
recording, while on your modem.

C&P is right.  Very few of the exchanges in the DC/Maryland area are
able to disable call waiting on a per call basis.  The ones that do
have it are also the ones that don't go "click" before beeping.  It's
the click that causes my modem to hang up.  The beep just causes noise.

Yep, "cancel call waiting" (1077 on pulse service) is not a part
of the basic "call waiting" service.  I had call waiting on my Pac*Tel
service for a year and a half before they announced that cancel call
waiting was available (and free).

Write to the C&P business office and request that they make cancel call
waiting available. (Tell them that you don't like having certain personal
calls disturbed: don't tell them about the modem!)
