[comp.dcom.telecom] Panasonic Doorphone

In a previous post, I railed about AT&T's part in keeping me from
obtaining a Doorphone for my Panasonic PBX. Since then I have received
E-Mail and even a phone call giving me suggestions on places to try. I
appreciate that very much. However, I have already tried all of them,
including the most widely-mentioned place, ProCom in San Diego. It was
a lady there who brought up the AT&T business as an explanation
concerning why that item was so hard to get.

Necessity being the mother of invention, I proceeded to analyze the
output of the doorphone adaptor, did a little breadboarding, and
faster than you can say "trade embargo", I now have a working
doorphone installed.  The circuit and transducers fit nicely in an
intercom door box.

Technology IS power, after all!
