DESCRIPTION
"The MIB module to describe DS1, J1, E1, DS2, and
E2 interfaces objects.
Copyright (c) The IETF Trust (2007). This
version of this MIB module is part of RFC 4805;
see the RFC itself for full legal notices."
REVISION "200703050000Z"
DESCRIPTION
"The following changes were made:
(1) Values were added to dsx1LineType to
support J1 types.
(2) The object dsx1LineImpedance was added.
(3) All DM-related objects were deprecated
following their removal from ITU performance
standards.
The RFC 4805 version of this MIB module."
REVISION "200409090000Z"
DESCRIPTION
"The RFC 3895 version of this MIB module.
The key changes made to this MIB module
since its publication in RFC 2495 are as follows:
(1) The dsx1FracIfIndex SYNTAX matches the description
range.
(2) A value was added to dsx1TransmitClockSource.
(3) Values were added to dsx1LineType.
(4) Two objects were added, dsx1LineMode and
dsx1LineBuildOut, to better express transceiver
mode and LineBuildOut for T1.
(5) Reference was added to Circuit Identifier object.
(6) Align the DESCRIPTION clauses of few statistic
objects with the near-end definition, with the far-end
definition, and with RFC 3593.
(7) Changes in Compliance Statements to include new
objects.
(8) A typographical error in dsx2E2 was fixed; the new name
is dsx1E2."
REVISION "199808011830Z"
DESCRIPTION
"The RFC 2495 version of this MIB module.
The key changes made to this MIB module
since its publication in RFC 1406 are as follows:
(1) The Fractional table has been deprecated.
(2) This document uses SMIv2.
(3) Usage is given for ifTable and ifXTable.
(4) Example usage of ifStackTable is included.
(5) dsx1IfIndex has been deprecated.
(6) Support for DS2 and E2 has been added.
(7) Additional lineTypes for DS2, E2, and unframed E1
were added.
(8) 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.
(9) An inward loopback has been added.
(10) Additional lineStatus bits have been added for Near
End in Unavailable Signal State, Carrier Equipment
Out of Service, DS2 Payload AIS, and DS2 Performance
Threshold.
(11) A read-write line Length object has been added.
(12) Signal mode of other has been added.
(13) Added a lineStatus last change, trap and enabler.
(14) The e1(19) ifType has been obsoleted, so this MIB
does not list it as a supported ifType.
(15) Textual Conventions for statistics objects have
been used.
(16) A new object, dsx1LoopbackStatus, has been
introduced to reflect the loopbacks established
on a DS1 interface and the source to the requests.
dsx1LoopbackConfig continues to be the desired
loopback state while dsx1LoopbackStatus reflects
the actual state.
(17) A dual loopback has been added to allow the setting
of an inward loopback and a line loopback at the
same time.
(18) An object indicating which channel to use within a
parent object (i.e., DS3) has been added.
(19) An object has been added to indicate whether or
not this DS1/E1 is channelized.
(20) Line coding type of B6ZS has been added for DS2."
