RFC3593. RFC3593.
(5) Add new value, dsx3M13, to dsx3LineType. (5) Add new value, dsx3M13, to dsx3LineType.
1.2. Changes from RFC1407
The changes from RFC1407 are the following:
(1) The Fractional Table has been deprecated.
(2) This document uses SMIv2.
(3) Values are given for ifTable and ifXTable.
(4) Example usage of ifStackTable is included.
(5) dsx3IfIndex has been deprecated.
(6) The definition of valid intervals has been clarified
for the case where the agent proxied for other devices. In
particular, the treatment of missing intervals has been
clarified.
(7) An inward loopback has been added.
(8) Additional lineStatus bits have been added for Near End
in Unavailable Signal State, Carrier Equipment Out of
Service.
(9) A read-write line Length object has been added.
(10) Added a lineStatus last change, trap and enabler.
(11) Textual Conventions for statistics objects have
been used.
(12) A new object, dsx3LoopbackStatus, has been introduced to
reflect the loopbacks established on a DS3/E3 interface and
the source to the requests. dsx3LoopbackConfig continues
to be the desired loopback state while dsx3LoopbackStatus
reflects the actual state.
(13) A dual loopback has been added to allow the setting of an
inward loopback and a line loopback at the same time.
(14) An object has been added to indicated whether or not this
is a channelized DS3/E3.
(15) A new object has been added to indicate which DS1 is to set
for remote loopback.
