[comp.dcom.telecom] Caller-ID Data Scheme

cdi@labrea.stanford.edu (02/20/91)

There was a title in this conference called "Re: Caller-ID Information
Decoding". I had meant to ask some questions on this subject myself,
and then missed reading this message. I had hoped that either this
message could be reposted if it were relevant or someone might find my
question interesting enough to want to answer.

      1. What is the data scheme used in calling number delivery?  I
have been told the baud rate is 1200 baud, but that the data scheme is
an old Bell data scheme that Rockwell does not support in their
datacomm chip sets.

      2. How do you get a modem to do on-hook communications?

      3. Does anyone know of a modem with this data-scheme?

      Last: Is the Bellcore Pub. TR-TSY-000031 "CLASS Feature: Calling
      Number Delivery" really worth the thirty dollars for this sort of
      information?

      What I was hoping to do is use this with my voice mail, which I
use as an answering machine, to aid in telling me who called and to route
specific messages for some of those calls, or call-forward them.
