A friend of mine has a cheapo phone that chirps every night at 11:55pm. A call to New York Telephone about this got a response claiming that NYT did no regular testing that would cause this. A telephone on the same line with a mechanical ringer does not make any noise. 1) What is causing this noise? 2) Is their an easy way to stop it? roger@cornell.uucp roger@crnlcs.bitnet roger@svax.cs.cornell.edu

Probably some kind of high-voltage line transient, maybe even some kind of induced voltage. There may be a big DC motor somwhere that kicks on at 11:55, whose power cables are close to the phone line. Even a lighting circuit might do it. Have him pick the phone up at 11:54 pm and find out what he hears when the signal that causes the chirp comes over the line. This can give some good indication as to the nature of the thing. In addition, taking the line off hook will cause such a thing. >2) Is their an easy way to stop it? Sure. Stop buying cheapo phones, and the problem will go away. -- Scott Dorsey Kaptain_Kludge ICS Programming Lab (Where old terminals go to die), Rich 110, Georgia Institute of Technology, Box 36681, Atlanta, Georgia 30332 ...!{akgua,allegra,amd,hplabs,ihnp4,seismo,ut-ngp}!gatech!gitpyr!kludge

I'd completely forgotten about this. When we lived in Chicago, our bedroom phone would chirp at 7am on the dot, every weekday. After we stopped being annoyed by it, it became a useful alarm clock. chris
