The RFC 2558 version of this MIB module. The key changes made to this MIB module since its initial publication in RFC 1595 are as follows. (1) The MODULE-IDENTITY has been updated to reflect the changes to the MIB. (2) Where applicable, the textual conventions PerfCurrentCount and PerfIntervalCount from PerfHist-TC-MIB have been used in place of Gauge32. (3) An agent now has the option to delay updates to the various performance counts in lieu of performing retroactive adjustments upon entering into or exiting from unavailable time. This implementation option is described in Appendix A of this memo. (4) In order to make the SONET-MIB more useful for circuit provisioning, the formerly read-only objects sonetMediumType, sonetMediumLineCoding, sonetMediumLineType, and sonetMediumCircuitIdentifier have been given a MAX-ACCESS of read-write. The MIN-ACCESS remains read-only. (5) The DESCRIPTION clause for sonetMediumTimeElapsed has been updated to describe its behaviour if the duration of the current interval exceeds the maximum value. (6) The DESCRIPTION clause for sonetMediumValidIntervals has been updated to describe its behaviour when some intervals may be unavailable, and the object sonetMediumInvalidIntervals has been added to keep count of the number of missing intervals (if any). (7) The object sonetMediumLoopbackConfig has been added to enable or disable loopback configurations. (8) Because the error count thresholds for declaring severely errored seconds that are specified in ANSI T1.231-1993, ITU-T G.826-1995, and ANSI T1.231-1997 are all different from each other and from the thresholds specified in RFC 1595, an enumerated INTEGER object sonetSESthresholdSet has been added to allow an agent to specify which threshold set is in use. Text has been added to Section 3 stating that if this object is not implemented the thresholds specified in RFC 1595 should be assumed, and the table containing those thresholds has been moved to Appendix B of this memo. (9) A column with SYNTAX TruthValue has been added to each interval table. The purpose of the additional column is to indicate, for each interval, whether the data is valid in the sense intended by ANSI T1.231 clause 9.1.2.2 [T1.231a][T1.231b]. The objects in question are: sonetSectionIntervalValidData sonetLineIntervalValidData sonetFarEndLineIntervalValidData sonetPathIntervalValidData sonetFarEndPathIntervalValidData sonetVTIntervalValidData sonetFarEndVTIntervalValidData (10) The ranges for sonetPathCurrentStatus and sonetVTCurrentStatus have been made consistent with the DESCRIPTION clauses. (11) The conformance information has been updated. Previous conformance information from RFC 1595 has been deprecated. Some typographical errors in the deprecated section have been corrected in order to prevent MIB compilation errors.
