DESCRIPTION "The MIB module to describe SONET/SDH interface objects. Copyright (C) The Internet Society (2003). This version of this MIB module is part of RFC yyyy; see the RFC itself for full legal notices." -- RFC Ed.: replace yyyy w/actual RFC number & remove this notice REVISION "200301020800Z" DESCRIPTION "The key changes made to this MIB module since its publication in RFC 2558 are as follows. (1) Corrected typographical error (bellcore1991(2) in sonetSESthresholdSet) (2) Added support for sts192cSTM64(6) and sts768cSTM256(7) in sonetPathCurrentWidth (3) Corrected description of the applicability of VTs for SDH for improved accuracy (4) Added clarification in the SES description that CV counts should be frozen during SESs (5) Corrected typographical errors: - Line Alarm Indication Signal description of the Terminology section (20.5 --> 2.5 seconds) - In the Terminology section sonetSESThresholdSet --> sonetSESthresholdSet " REVISION "199810190000Z" DESCRIPTION "The RFC 2558 version of this memo. 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."

Update the signal state and shift the one- -- second CV counts and ES/SES flags into the 10-element -- delay line. Note that far-end one-second statistics are -- to be flagged as "absent" during any second in which -- there is an incoming defect at the layer in question or -- at any lower layer. -- -- iii) Update the current interval statistics using the signal -- state from the previous update cycle and the one-second -- CV counts and ES/SES flags shifted out of the 10-element -- delay line. -- -- This procedure guarantees that the statistical counters will -- be correctly updated at all times, although they lag real time -- by 10 seconds. It is illustrated in the figure below. At the -- end of each 15 minutes interval the current interval counts -- are transferred to the most recent interval entry and each -- interval is shifted up by one position, with the oldest being -- discarded if necessary in order to make room. The current -- interval counts then start over from zero. Note, however, -- that the signal state calculation does not start anew at each -- interval boundary; rather, signal state information is -- retained across interval boundaries. -- +--------------------------------------------------------------+ -- | READ COUNTERS & STATUS INFO FROM HARDWARE | -- | | -- |LOS OOF/ SECT LINE LINE LINE LINE PATH PATH PATH PATH PATH | -- | LOF CV AIS CV RDI FEBE AIS LOP CV RDI CV | -- +--------------------------------------------------------------+ -- | | | | | | | | | | | | -- | | | | | | | | | | | | -- V V V V V V V V V V V V -- +--------------------------------------------------------------+ -- | ACCUM ONE-SEC STATS, CHK ERR THRESHOLDS, & UPDT SIGNAL STATE | -- | | -- | | -- | NEAR END/FAR END NEAR END/FAR END | -- |SECT SECT SECT LINE LINE LINE LINE PATH PATH PATH PATH | -- |CV ES SES CV ES SES AVA/UNA CV ES SES AVA/UNA | -- +--------------------------------------------------------------+ -- | | | | | | | | | | | -- | | | | | | | | | | | -- V V V V V V | V V V | -- +-------------+ +-------------+ | +-------------+ | -- |ONE-SEC DELAY| |ONE-SEC DELAY| | |ONE-SEC DELAY| | -- | (1 OF 10) | | (1 OF 10) | | | (1 OF 10) | | -- |CV ES SES| |CV ES SES| | |CV ES SES| | -- +-------------+ +-------------+ | +-------------+ | -- | | | | | | | | | | | -- / / / / / / / / / / / -- / / / / / / / / / / / -- | | | | | | | | | | | -- V V V V V V | V V V | -- +-------------+ +-------------+ | +-------------+ | -- |ONE-SEC DELAY| |ONE-SEC DELAY| | |ONE-SEC DELAY| | -- | (10 OF 10) | | (10 OF 10) | | | (10 OF 10) | | -- |CV ES SES| |CV ES SES| | |CV ES SES| | -- +-------------+ +-------------+ | +-------------+ | -- | | | | | | | | | | | -- | | | | | | | | | | | -- V V V V V V V V V V V -- +--------------------------------------------------------------+ -- | UPDATE STATISTICS COUNTERS | -- | | -- | NEAR END/FAR END NEAR END/FAR END | -- | SECTION LINE PATH | -- | CV ES EFS SES CV ES EFS SES AS UAS CV ES EFS SES AS UAS | -- +--------------------------------------------------------------+ -- Note that if such a procedure is adopted there is no current -- interval data for the first ten seconds after a system comes -- up. noSuchInstance must be returned if a management station -- attempts to access the current interval counters during this -- time. -- -- It is an implementation-specific matter whether an agent -- assumes that the initial state of the interface is available -- or unavailable. -- Appendix B - RFC 1595 SES interpretation -- -- This appendix contains the values for x for the Section, Line, -- Path, and VT Layers as used in [T1M1.3][RFC1595][TR253]. -- -- Value for x for SONET/SDH Section SES Definition -- -- Rate x Minimum Bit Error Rate -- ======================================================= -- OC-1 9 1.5 x 10^-7 -- OC-3 16 1 x 10^-7 -- OC-9 47 1 x 10^-7 -- OC-12 63 1 x 10^-7 -- OC-18 94 1 x 10^-7 -- OC-24 125 1 x 10^-7 -- OC-36 187 1 x 10^-7 -- OC-48 249 1 x 10^-7 -- -- -- Value for x for SONET/SDH Line SES Definition -- -- Rate x Minimum Bit Error Rate -- ======================================================= -- OC-1 12 2 x 10^-7 -- OC-3 32 2 x 10^-7 -- OC-9 47 2 x 10^-7 -- OC-12 124 2 x 10^-7 -- OC-18 186 2 x 10^-7 -- OC-24 248 2 x 10^-7 -- OC-36 370 2 x 10^-7 -- OC-48 494 2 x 10^-7 -- -- -- Value for x for SONET/SDH STS-Path SES Definition -- -- Rate x Minimum Bit Error Rate -- ======================================================= -- STS-1 9 1.5 x 10^-7 -- STS-3 16 1 x 10^-7 -- Value for x for SONET/SDH VT-Path SES Definition -- -- Rate x Minimum Bit Error Rate -- ======================================================= -- VT1.5 4 2 x 10^-6 -- VT2 6 2 x 10^-6 -- VT3 8 2 x 10^-6 -- VT6 14 2 x 10^-6 -- ************************************************************ -- * NOTES TO RFC Editor (to be removed prior to publication) * -- * * -- * 1.)
