Minutes of the Modem Management Working Group (MODEMMGT)


Summary

The third meeting of MODEMMGT was attended by twenty or so people.  The
Network Management Area Director noted that the group was behind
schedule and would be given until January 31, 1994 to reach consensus or
the working group would be disbanded.

The group discussed various ways to meet this deadline and agreed to
pursue a phased approach.  The group will focus on a MIB of core objects
and defer other objects to a MIB of extensions.

It was suggested that the group reconsider the work done by the CCITT
(now ITU) known as V.im (now V.58).  It was agreed that V.58 would be
considered a super-set of objects from which the set of core objects
would be taken.  Objects could be renamed and be explicitly mapped to
the corresponding V.58 object with notes in the description.  Changes in
structure would be made only where justified.

The structure of the working group's draft of the core objects was
analyzed.  It was agreed that it would be reduced to five groups of
objects.  The objects within each group will be refined by the authors.
The grouping of core objects is as follows:


 mdmIDGroup            Identity of the modem
 mdmLineInterfaceGroup Configuration and state of line interface
 mdmDTEInterfaceGroup  Configuration and state of DTE interface
 mdmCallControlGroup   Call control configuration and state of last call
 mdmStatisticsGroup    Statistics of the modem



Internet-Draft Discussion

   o The group agreed NOT to include leased line functionality in the
     core MIB.

   o The mdmIDGroup corresponds to the VSeriesDcePackage in V.58

   o The mdmDataCompressionGroup was dropped from the core MIB.

   o The mdmCallControlGroup and mdmCallStateGroup were merged into the
     mdmCallControlGroup like V.58

   o The mdmSignalConverterGroup was dropped from the core MIB.

   o The mdmIDModel object was expanded to include the revision, serial
     number, hardware revision, and firmware revision like
     manufacturerID in V.58.

   o Objects mdmIDHardwareSerNum, mdmIDHardwareRev, mdmIDFirmwareRev are
     dropped from the draft.

   o mdmIDCountry was deferred to an extension MIB.

   o mdmLineCapabilitiesTable was considered.  The documented technique
     is different from V.58.  The merits of this deviation were argued
     but to resolved.  Steve Waldbusser will defend the draft method in
     a discussion on the mailing list.  Alan Clark will argue for a
     method more in line with V.58 on the mailing list.

   o The mdmStats group was compared to V.58.  The working group wanted
     to deviate from V.58 and leave the statistics in a separate group.


The Next Step

The five groups of core objects will be divided among the authors for
further editing.  Each group will be treated individually on the mailing
list.  The groups must be carefully evaluated and extensively discussed
on the mailing list.  Thanks to those who have contributed time and
expertise to this project.
