Danny and Tony,
I found the rest of the document, including the section on time
stamping. It appears that the main thrust of the document is CDMA2000
and VoIP, specifically packet voice services, although it can be
interpreted for other services as well. It looks like the carriers
wanted to avoid extra work for packet voice services and omitted
timestamping in the current voluntary industry standard. See the
fascinating link at http://www.fcc.gov/calea/.
The DoJ and FBI strategy apparently is to request the FCC to promote the
DoJ position as a rulemaking issue. That is an interesting strategy, as
formerly the carriers operated with a voluntary industry standard. The
Feds didn't get what they wanted in the industry standard, so now they
want the FCC to be the hammer.
The issue on timestamping says nothing about NTP, just the accuarcy
requirement of 200 ms and delivery of the intercept within 8 s. It says
nothing about UTC or NIST/USNO traceability.
