Right. But they do have veto power, and they do not appear to have given
approval yet. Meanwhile the deadline continues to close. This is an
awkward situation.

Yeah those are mentioned in FCC-05-06 as near completion.

It looks like t1.678 is most applicable to the area I'm primarily
interested in, since it describes voice-over-packet interfaces in general,
and mappings for SIP and H.323 in particular (although it seems that the
LEA interface is undefined, and also seems to assume some kind of circuit-
or local delivery, all of which is quite curious--this is what the IETF
guys call out as hand-waving).

For the DOCSIS equipment you mean? That's a whole 'nother world from the
RFC3924 stuff.
