[comp.dcom.telecom] Questions About The Call Waiting Feature

gonzalez@bbn.com (Jim Gonzalez) (02/19/89)

A college acquaintance of mine has call waiting on his line, as a cheap
alternative to a second line for his modem.  Every time he got a noise
burst, he would break his terminal session and check for the other call.
Of course, not every noise burst was caused by a call waiting tone, and
he ended up with unwanted interruptions.

Can anyone provide a description of the tone, including the frequency and
period?  I've never used such a line, but know that you get more than the
click the primary caller hears.  Are there detection circuits commercially
available?

Also, YAWNS (Yet Another Wrong-Number Story :-).  I've been getting calls
about once a week from this woman who, I have since learned, was dialing a
number for a different exchange but with the same last four digits.  Is it
possible that her CO is misdirecting the call?  The exchanges in question
rule out a simple misdial on Touch Tone or rotary phone.  I successfully
called the correct party, who has been getting calls from other people
without a hitch, but has *never* heard from the woman who has been calling
me.  Aren't computers wonderful?  I'm sure the story will get better when
New England Telephone starts trying to fix this :-).
