Comments on new draft-ietf-atomib-rfc2558bis-01.txt

I note that there is no mention of the current performance ITU-T
Recommendation G.828 which has replaced G.826 for new work.
ITU-T G.828 calls for higher performance than G.826 and also introduces
a recognition of short interrupt events that were not part of G.826. 

There is also a hidden assumption in the older recommendations that an
SES is the same throughout the signal processing involved in terminating
line systems. This assumption no longer holds as it has been recognised
that there is so much processing in modern line systems that an SES will
be declared at some layers but not at others. This only happens on the
border line, of course, but in the modern commercial environment of
telecomms it is important.

The heavy reliance on American standards is non-optimum for
international connections. Is this really necessary? There are several
ITU-T recommendations for maintenance issues in the M series which have
been agreed internationally.

For Transport systems using satellites the relevant ITU-R
recommendations are S.1521 for error performance, S.1522 for short
interrupts and S.579 for availability (under extensive revision along
with the corresponding ITU-T recommendation G.827). There is a similar
set of ITU-R recommendations for the microwave radio relay transmission
systems.

I hope that this draft may be revised to include these few comments.
