RE: [Raven] Clarifying questions
I think the traditional terms are:
1. "Pen register" gives time of calls and digits dialed by subject.
2. "Trap and trace" gives time of calls and number of party calling subject
(basically, Caller ID)
3. "Intercept" means, listen in on/record the content of the communications.
In packet-mode, one issue is, how do you give the LEA only the equivalent of
digits dialed/calling party number without also giving the content (which
requires a more involved court authorization)? What the FCC said (if I
understand it correctly) is that the "base" standard -- give the LEA the
whole thing and let them sort it out -- applies starting 9/01, but they
asked TIA to keep working on it and report back to them by 9/00.
