RE: [EFM] Communication statement from T1E1- Is there a hidden meaning here?
Alan,
Not surprisingly, this was well-discussed at the T1E1.4. TRQ's did not
exist when the CAP specification was adopted. As described at T1E1.4 by
the experts, a TRQ, now that it exists is more appropriate for this type
of specification than a TR, as it is intended to contain normative text,
but it not a "standards track" document and does not have ANSI review.
An example was given that the Number Portability Specifications in T1
are TRQ's.
The Committee T1 Procedures Manual, found on their website, describes
TRQs.

All
About 6 years ago, T1E1.4 made a similar decision with respect to ADSL
issue 2. They decided to develop std T1-413 (ADSL) issue II based on
DMT and develop a technical report for CAP/QAM based ADSL, which held a
very respectable % of a then small ADSL market. Soon thereafter, the
ADSL Forum chose only to work with DMT based ADSL. A few years later,
DMT based ADSL overwhelmed CAP/QAM, which eventually disappeared.
T1E1's decision to go with DMT for the VDSL standard appears to be
similar to the 1997 ADSL decision- a standard has more industry
acceptance than a Technical Requirements document, as it provides more
detail and depth needed for interoperability.
However, there is one unknown: what is a T1 Technical Requirement
document? Have any ever been published and, if so, what happened to the
referenced technology? Is such a Requirements document sufficient to
ensure multi-vendor interoperability- at the chip and system level?
Perhaps, some T1E1 experts could enlighten us on this point
