At a local sysops' gathering tonight, the subject of Caller*ID <tm>
came up and it was mentioned by one participant that he had heard that
the Class- Mate <tm> would not work in US West territory, supposedly
due to differences in the way US West sends the CLID data.

Class-Mate is a widget that connects between a CLID-equipped phone
line and a computer's line that converts the incoming CLID data to
serial data that may be captured by the computer.  It's is available
from Bell Atlantic and possibly other sources.

Is it >>REALLY<< the case that US West uses a different scheme for
CLID??  I am now using a CLID box that I got from Hello Direct -- the
same box that is sold to non-US West subscribers, as far as I know.
The box works fine here, and I know the same model CLID box works in
New Jersey as well.
 
Also, I had the impression that the Class-Mate was more or less a
passive device that demodulated the CLID data and converted it to
RS-232 compatible levels, and did not really do any heavy-duty data
conversion.  Am I correct in assuming this.  Thanks.
 

Good Day!       JSW


[Moderator's Note: Since an ultimate goal is to make Caller-ID
available to everyone on all calls throughout the USA I would think
the individual systems throughout the country are compatible.   PAT]
