[comp.dcom.telecom] Caller ID Tech Specs Needed

sreekanth@rgb.dec.com (Jon Sreekanth) (09/08/90)

I'm looking for technical specs on telephone caller ID. All I know is
that it's an FSK signal during ringing, but I'd like to get more
details, or a pointer to where I can obtain (buy) tech. info.

Also, is the implementation standardised nationwide, across all
Bells?  What geographical areas currently have it?

Thanks, 

Jon Sreekanth
