The Internet-Standard Management Framework + + For a detailed overview of the documents that describe the current + Internet-Standard Management Framework, please refer to section 7 of + RFC 3410 [RFC3410]. + + Managed objects are accessed via a virtual information store, termed + the Management Information Base or MIB. MIB objects are generally + accessed through the Simple Network Management Protocol (SNMP). + Objects in the MIB are defined using the mechanisms defined in the + Structure of Management Information (SMI). This memo specifies a MIB + module that is compliant to the SMIv2, which is described in STD 58, + RFC 2578 [RFC2578], STD 58, RFC 2579 [RFC2579] and STD 58, RFC 2580 + [RFC2580]. + + Textual conventions used in this document are defined in RFC 2579 + [RFC2579] and RFC 3593 [RFC3593]. + +3. Overview + + These objects are used when the particular media being used to + realize an interface is a SONET/SDH interface. At present, this + applies to these values of the ifType variable in the Internet- + standard MIB: + + sonet (39), sonetPath (50), sonetVT (51) + + The definitions contained herein are based on the SONET/SDH + specifications in ANSI T1.105 and T1.106-1988 + [T1.105a][T1.105b][T1.106] and CCITT G.707, 708, 709, and G.783 + [G.707][G.708][G.709][G.783]. + +3.1. Use of the ifTable + + This section specifies how the MIB II interfaces group, as defined in + [RFC2863], is used for SONET/SDH interfaces. The SONET/SDH layers + support several multiplexing possibilities. + + For example in SONET, an Synchronous Transport Signal 3 (STS-3) has 3 + SONET Paths, and a STS-3c has 1 SONET Path. Another example could be + a STS-12 having 4 SONET STS-3c Paths. Similarly, a SONET Synchronous + Payload Envelope (SPE) can carry many Virtual Tributaries (VTs), for + example, one SONET SPE can carry 28 VT1.5s. It is important to note + that an SPE and a VT in SONET is collectively referred to as a + Virtual Container (VC) in SDH. Also, an STS is called Synchronous + Transport Module (STM) in SDH. + + + + + +Tesink Standards Track [Page 3] + +RFC 3592 SONET/SDH Objects September 2003 + + + Not all SONET/SDH equipment terminates all SONET/SDH layers. For + example, a SONET/SDH STE regenerator terminates SONET/SDH Sections + only, and is transparent for all layers above that. SONET/SDH Add- + Drop multiplexers and Digital Cross Connect Systems terminate + SONET/SDH Lines. SONET/SDH Terminal Multiplexers may also terminate + SONET/SDH Paths and VTs/VCs. + + MIB II [RFC1213], as extended by [RFC2863], accommodates these cases + by appropriate use of the MIB II system group, and the interfaces + group. The system group can name and describe the type of managed + resource. The interfaces group defines which SONET/SDH layers apply, + how these layers are configured and multiplexed. This is achieved by + proper representation of SONET/SDH Layers by ifEntries as defined in + [RFC2863], as follows: + + _____________________________ + | | | | > + | | | | | + | VT 1 |..........|VT K| > K ifEntries + | | | | | + |_____________|__________|____| > + | | | | > + | | | | | + | Path 1 |......|Path L| > L ifEntries + | | | | | + |_______________|______|______| > + | | > + | | | + | Line | | + | | | + |_____________________________| | + | | | + | | | + | Section Layer | > 1 ifEntry + | | | + |_____________________________| | + | | | + | | | + | Physical Medium Layer | | + | | | + |_____________________________| > + + Use of ifTable for a SONET/SDH port + + The exact configuration and multiplexing of the layers is maintained + in the ifStackTable [RFC2863] and in the ifInvStackTable [RFC2864]. + + + + + +Tesink Standards Track [Page 4] + +RFC 3592 SONET/SDH Objects September 2003 + + +3.2.

SONET/SDH Terminology + + The terminology used in this document to describe error conditions on + a SONET circuit as monitored by a SONET system are from the T1.231 + [T1M1.3][T1.231a][T1.231b].

Only the SONET Performance + + + +Tesink Standards Track [Page 7] + +RFC 3592 SONET/SDH Objects September 2003 + + + Monitoring terminology is defined in this document. The definitions + for SDH Performance Monitoring terms are similar but not identical, + and they can be found in [G.783]. If the definition in this document + does not match the definition in the T1.231 document, the implementer + should follow the definition described in this document. In some + cases other or additional references are used as compared with the + ones cited above. This will be indicated in the text. + + Section Loss Of Frame Failure (Out of Frame Event, Severely + Errored Frame Defect) An Out of Frame (OOF) event (or Severely + Errored Frame defect) is the occurrence of four contiguous errored + frame alignment words. A frame alignment word occupies the A1 and + A2 bytes of an STS frame, and is defined in T1.105. The SEF + defect is terminated when two contiguous error-free frame words + are detected. Any implementation of the frame recovery circuitry + which achieves realignment following an OOF within the 250 + microsecond (two frames) interval implied by this definition is + acceptable. + + A Loss of Frame (LOF) defect is declared when an OOF/SEF defect + persists for a period of 3 milliseconds. The LOF defect is + terminated when the incoming signal remains continuously in-frame + for a period of 1 ms to 3 ms. + + A LOF failure is declared when the LOF defect persists for a + period of 2.5 +/- 0.5 seconds, except when an LOS defect or + failure is present. The LOF failure is cleared when the LOS + failure is declared, or when the LOF defect is absent for 10 +/- + 0.5 seconds. + + Loss of Signal + The Loss of Signal (LOS) defect is declared when no transitions + are detected on the incoming signal (before descrambling). The + LOS defect is detected upon observing 2.3 to 100 microseconds of + no transitions. The LOS defect is cleared after a 125 microsecond + interval (one frame) during which no LOS defect is detected. + + The LOS failure is declared when the LOS defect persists for a + period of 2.5 +/- 0.5 seconds, or if LOS defect is present when + the criteria for LOF failure declaration have been met. The LOS + failure is cleared when the LOS defect is absent for a period of + 10 +/- 0.5 seconds. Declaration of LOS failure clears any + existing LOF failure. Clearing the LOS failure allows immediate + declaration of the LOF failure if conditions warrant. + + + + + + + +Tesink Standards Track [Page 8] + +RFC 3592 SONET/SDH Objects September 2003 + + + STS-Path Loss of Pointer + A Loss of Pointer (LOP) defect is declared when either a valid + pointer is not detected in eight consecutive frames, or when eight + consecutive frames are detected with the New Data Flag (NDF) set + to "1001" without a valid concatenation indicator (see ANSI + T1.105). A LOP defect is terminated when either a valid pointer + with a normal NDF set to "0110", or a valid concatenation + indicator is detected for three contiguous frames. Incoming STS- + Path AIS shall not result in the declaration of a LOP defect. + + An STS-Path LOP failure is declared when the STS-Path LOP defect + persists for a period of 2.5 +/- 0.5 seconds. A STS-Path LOP + failure is cleared when the STS-Path LOP defect is absent for 10 + +/- 0.5 seconds. + + VT Loss of Pointer + A VT LOP defect is declared when either a valid pointer is not + detected in eight consecutive VT superframes, or when eight + consecutive VT superframes are detected with the NDF set to "1001" + without a valid concatenation indicator. A VT LOP defect is + terminated when either a valid pointer with a normal NDF set to + "0110", or a valid concatenation indicator is detected for three + contiguous VT superframes. Incoming VT-Path AIS shall not result + in declaring a VT LOP defect. + + A VT LOP failure is declared when the VT LOP defect persists for + 2.5 +/- 0.5 seconds. A VT LOP failure is cleared when the VT LOP + defect is absent for 10 +/- 0.5 seconds. + + Line Alarm Indication Signal + A Line Alarm Indication Signal (L-AIS) is defined in ANSI T1.105. + The following criteria are specific to the L-AIS defect: + + - Line AIS defect is detected as a "111" pattern in bits 6, 7, + and 8 of the K2 byte in five consecutive frames. + + - Line AIS defect is terminated when bits 6, 7, and 8 of the K2 + byte do not contain the code "111" for five consecutive frames. + + A Line AIS failure is declared when the Line AIS defect persists + for a period of 2.5 +/- 0.5 seconds. A Line AIS failure is + cleared when the Line AIS defect is absent for 10 +/- 0.5 seconds. + + STS-Path Alarm Indication Signal + The STS-Path Alarm Indication Signal (AIS) is defined in ANSI + T1.105 as all ones in bytes H1, H2, and H3 as well as all ones in + the entire STS SPE. The following criteria are specific to the + STS-Path AIS defect: + + + +Tesink Standards Track [Page 9] + +RFC 3592 SONET/SDH Objects September 2003 + + + - STS-Path AIS defect is detected as all ones in bytes H1 and H2 + in three contiguous frames. + + - The STS-Path AIS defect is terminated when a valid STS Pointer + is detected with the NDF set to "1001" (inverted) for one + frame, or "0110" (normal) for three contiguous frames. + + An STS-Path AIS failure is declared when the STS-Path AIS defect + persists for 2.5 +/- 0.5 seconds. An STS-Path AIS failure is + cleared when the STS-Path AIS defect is absent for 10 +/- 0.5 + seconds. + + VT-Path Alarm Indication Signal + The VT-Path Alarm Indication Signal (AIS) is only applicable for + VTs in the floating mode of operation. VT-Path AIS is used to + alert the downstream VT Path Terminating Entity (PTE) of an + upstream failure. Upon detection of a failure, Line AIS, or STS- + Path AIS, an STS PTE will generate downstream VT-Path AIS if the + STS Synchronous Payload Envelope (SPE) is carrying floating VTs. + VT-Path AIS is specified in ANSI T1.105 as all ones in bytes V1, + V2, V3, and V4, as well as all ones in the entire VT SPE. The + following criteria are specific to VT-Path AIS defect: + + - VT-Path AIS defect is detected by a VT PTE as all ones in bytes + V1 and V2 in three contiguous VT superframes. + + - VT-Path AIS defect is terminated when valid VT pointer with a + valid VT size is detected with the NDF set to "1001" (inverted) + for one VT superframe, or "0110" (normal) for three contiguous + VT superframes are detected. + + A VT-Path AIS failure is declared when the VT-Path AIS defect + persists for 2.5 +/- 0.5 seconds. A VT-Path AIS failure is + cleared when the VT-Path AIS defect is absent for 10 +/- 0.5 + seconds. + + Line Remote Defect Indication + Line Remote Defect Indication (RDI) (aka Line FERF) signal is the + occurrence of a "110" pattern in bit positions 6, 7, and 8 of the + K2 byte in STS-1 #1 of the STS-N signal. Line RDI is defined in + ANSI T1.105. The following criteria are specific to Line RDI + defect: + + - Line RDI defect is a "110" code in bits 6, 7, and 8 of the K2 + byte of in STS-1 #1 in x consecutive frames, where x = 5 + [T1.231a][T1.231b] or 10 [T1.231b]. + + + + + +Tesink Standards Track [Page 10] + +RFC 3592 SONET/SDH Objects September 2003 + + + - Line RDI defect is terminated when any code other than "110" is + detected in bits 6, 7, and 8 of the K2 byte in x consecutive + frames, where x = 5 [T1.231a][T1.231b] or 10 [T1.231b]. + + A Line Remote Failure Indication (RFI) failure is declared when + the incoming Line RDI defects lasts for 2.5 +/- 0.5 seconds. The + Line RFI failure is cleared when no Line RDI defects are detected + for 10 +/- 0.5 seconds. + + STS-Path Remote Defect Indication + STS-Path RDI (aka STS-Path FERF) signal shall be generated within + 100 milliseconds by the STS PTE upon detection of an AIS or LOP + defect. Transmission of the STS-Path RDI signal shall cease + within 100 milliseconds when the STS PTE no longer detects STS- + Path AIS or STS-Path LOP defect. The STS-Path RDI shall + accurately report the presence or absence of STS-Path AIS or STS- + Path LOP defects. STS-Path RDI defect is defined in ANSI T1.105. + The following requirements are specific to the STS-Path RDI + defect: + + - STS-Path RDI is detected by all STS PTEs. STS-Path RDI is + detected by the upstream STS PTE as a "1" in bit five of the + Path Status byte (G1) for x consecutive frames, where x = 5 + [T1.231a] or 10 [T1.231b]. + + - Removal of STS-Path Remote Defect Indication is detected by a + "0" in bit 5 of the G1 byte in x consecutive frames, where x = + 5 [T1.231a] or 10 [T1.231b]. + + An STS-Path Remote Failure Indication (RFI) failure is declared + when the incoming STS-Path RDI defects lasts for 2.5 +/- 0.5 + seconds. The STS-Path RFI failure is cleared when no STS-Path RDI + defects are detected for 10 +/- 0.5 seconds. + + VT-Path Remote Defect Indication + VT Path RDI (aka VT Path FERF) signal shall be generated within 100 + milliseconds by the VT PTE upon detection of a VT-Path AIS or LOP + defect. Transmission of the VT-Path RDI signal shall cease within + 100 milliseconds when the VT PTE no longer detects VT-Path AIS or + VT-Path LOP defect. The VT-Path RDI shall accurately report the + presence or absence of VT-Path AIS or VT-Path LOP defects. VT- + Path RDI defect is defined in ANSI T1.105. The following + requirements are specific to VT-Path RDI defect: + + - VT-Path RDI defect is the occurrence of a "1" in bit 4 of the + VT-Path Overhead byte (V5) in x consecutive frames, where x = 5 + [T1.231a] or 10 [T1.231b]. + + + + +Tesink Standards Track [Page 11] + +RFC 3592 SONET/SDH Objects September 2003 + + + - VT-Path RDI defect is terminated when a "0" is detected in bit + 4 of the VT-Path Overhead byte (V5) for x consecutive frames, + where x = 5 [T1.231a] or 10 [T1.231b]. + + A VT-Path Remote Failure Indication (RFI) (derived) failure is + declared when the incoming VT-Path RDI defects lasts for 2.5 +/- + 0.5 seconds. The VT-Path RFI failure is cleared when no VT-Path + RDI defects are detected for 10 +/- 0.5 seconds. + + VT-Path Remote Failure Indication + The VT-Path RFI signal is only required for the case of byte synch + mapped DS1s where the DS1 frame bit is not mapped. The VT-Path + RFI is specified in ANSI T1.105, where it is currently called VT + path yellow. When provided, the VT-Path RFI signal is used to + indicate the occurrence of far-end failures. When the VT-Path RFI + is not provided, far-end failures are derived from local timing of + the VT-Path RDI defect. The VT-Path RFI failure is declared + within 5 ms of detecting the incoming VT-Path RFI Signal. The + VT-Path Remote Failure Indication (RFI) failure is cleared within + 50 ms of detecting the removal of the incoming VT-Path RFI signal. + + Coding Violation + Coding Violations (CV) are Bit Interleaved Parity (BIP) errors + that are detected in the incoming signal. CV counters are + incremented for each BIP error detected. That is, each BIP-8 can + detect up to eight errors per STS-N frame, with each error + incrementing the CV counter. Section CVs shall be collected using + the BIP-8 in the B1 byte located in the Section Overhead of STS-1 + #1. Line CVs shall be collected using the BIP-8s in B2 bytes + located in the Line Overhead of each STS-1 (since all CVs on an + STS-N line are counted together, this is equivalent to counting + each error in the BIP-8*N contained in the B2 bytes of the STS-N + Line Overhead). Thus, on an STS-N signal, up to 8 x N CVs may + occur in each frame. Path CVs shall be collected using the BIP-8 + in the B3 byte of the STS-Path Overhead of the STS SPE. VT CVs + shall be collected using the BIP-2 in the V5 overhead byte of the + floating VT. + + Errored Seconds + At each layer, an Errored Second (ES) is a second with one or more + Coding Violations at that layer OR one or more incoming defects + (e.g., SEF, LOS, AIS, LOP) at that layer has occurred. + + Severely Errored Seconds + According to [T1M1.3][T1.231a][TR253][GR253][T1.231b] at each + layer, an Severely Errored Second (SES) is a second with x or more + CVs at that layer, or a second during which at least one or more + incoming defects at that layer has occurred. The values of x in + + + +Tesink Standards Track [Page 12] + +RFC 3592 SONET/SDH Objects September 2003 + + + RFC 1595 [RFC1595] were based on [T1M1.3] and [TR253] (see + Appendix B). These values have subsequently been relaxed in + [T1.231a][GR253][T1.231b]. In addition, according to G.826 + [G.826] SESs are measured as a percentage of errored blocks. + + To deal with these sets of definitions this memo defines an object + sonetSESthresholdSet that determines the correct interpretation of + SES. For backward compatibility, if this object is not + implemented the interpretation of Appendix B shall apply. + Otherwise, a more recent interpretation is suggested. An agent is + not required to support all sets of definitions. + + Note that CV counts should be frozen during SESs. + + Note that if a manager changes the value of this object all SES + statistics collected prior to this change shall be invalidated. + + Severely Errored Framing Seconds + A Severely Errored Framing Second (SEFS) is a second containing + one or more SEF events. This counter is only counted at the + Section Layer. + + Unavailable Seconds + At the Line, Path, and VT layers, an unavailable second is + calculated by counting the number of seconds that the interface is + unavailable. At each layer, the SONET/SDH interface is said to be + unavailable at the onset of 10 contiguous SESs. The 10 SESs are + included in unavailable time. Once unavailable, the SONET/SDH + interface becomes available at the onset of 10 contiguous seconds + with no SESs. The 10 seconds with no SESs are excluded from + unavailable time. With respect to the SONET/SDH error counts at + each layer, all counters at that layer are incremented while the + SONET/SDH interface is deemed available at that layer. While the + interface is deemed unavailable at that layer, the only count that + is incremented is UASs at that layer. + + Note that this definition implies that the agent cannot determine + until after a ten second interval has passed whether a given one- + second interval belongs to available or unavailable time. If the + agent chooses to update the various performance statistics in real + time then it must be prepared to retroactively reduce the ES, SES, + and SEFS counts by 10 and increase the UAS count by 10 when it + determines that available time has been entered. It must also be + prepared to reduce the CV count by the number of violations + counted since the onset of unavailable time. The agent must be + similarly prepared to retroactively decrease the UAS count by 10 + and increase the ES and CV counts as necessary upon entering + available time. A special case exists when the 10 second period + + + +Tesink Standards Track [Page 13] + +RFC 3592 SONET/SDH Objects September 2003 + + + leading to available or unavailable time crosses a 900 second + statistics window boundary, as the foregoing description implies + that the CV, ES, SES, SEFS, and UAS counts the PREVIOUS interval + must be adjusted. In this case successive GETs of the affected + sonetPathIntervalSES and sonetPathIntervalUAS objects (and the + analogous Line and VT objects also) objects will return differing + values if the first GET occurs during the first few seconds of the + window. + + According to ANSI T1.231 unavailable time begins at the _onset_ of + 10 contiguous severely errored seconds -- that is, unavailable + time starts with the _first_ of the 10 contiguous SESs. Also, + while an interface is deemed unavailable all counters for that + interface are frozen except for the UAS count. It follows that an + implementation which strictly complies with this standard must + _not_ increment any counters other than the UAS count -- even + temporarily -- as a result of anything that happens during those + 10 seconds. Since changes in the signal state lag the data to + which they apply by 10 seconds, an ANSI-compliant implementation + must pass the one-second statistics through a 10-second delay line + prior to updating any counters. That can be done by performing + the following steps at the end of each one second interval. + + i) Read near/far end CV counter and alarm status flags from the + hardware. + + ii) Accumulate the CV counts for the preceding second and compare + them to the ES and SES threshold for the layer in question. + 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 approach is further described in Appendix A. An agent may + choose to use this approach in lieu of retroactive adjustments to + the counters. + + In any case, a linkDown trap shall be sent only after the agent + has determined for certain that the unavailable state has been + entered, but the time on the trap will be that of the first UAS + (i.e., 10 seconds earlier). A linkUp trap shall be handled + similarly. + + + + +Tesink Standards Track [Page 14] + +RFC 3592 SONET/SDH Objects September 2003 + + + Unequipped + If a Path or VT connection is not provisioned (idle) the SONET + equipment will signal this state by transmitting the Path or VT + Signal Label as follows: - byte C2 of the STS Path Overhead equal + to 0 for an unequipped Path, - byte V5 of the VT Path Overhead + equal to 0 for an unequipped VT. + + Signal Label Mismatch + A Path or VT connection is not correctly provisioned if a received + Path or VT Signal Label mismatch occurs.

Acknowledgments + + This specification is a product of the AToM MIB Working Group. The + author would like to acknowledge Mike Heard for his many valuable + contributions to this memo. + +6. Security Considerations + + There are a number of management objects defined in this MIB module + that have a MAX-ACCESS clause of read-write: sonetMediumType, + sonetMediumLineCoding, sonetMediumLineType, + sonetMediumCircuitIdentifier, sonetMediumLoopbackConfig, + sonetSESthresholdSet, sonetPathCurrentWidth, and sonetVTCurrentWidth. + It is possible for writes to these objects to have disruptive effects + on network operation that range from invalid performance data to + traffic interruptions. Users of this MIB module must therefore be + aware that support for SET operations in a non-secure environment + without proper protection can have a negative effect on network + operations. + + The readable objects in this MIB module (i.e., the objects with a + MAX-ACCESS other than not-accessible) may be considered sensitive in + some environments since, collectively, they provide extensive + information about the performance of interfaces in SONET/SDH + equipment or networks and can reveal some aspects of their + configuration. In such environments it is important to control even + GET and NOTIFY access to these objects and possibly to encrypt the + values of these objects when sending them over the network via SNMP. + + SNMP versions prior to SNMPv3 did not include adequate security. + Even if the network itself is secure (for example by using IPSec), + even then, there is no control as to who on the secure network is + allowed to access and GET/SET (read/change/create/delete) the objects + in this MIB module. + + It is RECOMMENDED that implementers consider the security features as + provided by the SNMPv3 framework (see [RFC3410], section 8), + including full support for the SNMPv3 cryptographic mechanisms (for + authentication and privacy). + + Further, deployment of SNMP versions prior to SNMPv3 is NOT + RECOMMENDED. Instead, it is RECOMMENDED to deploy SNMPv3 and to + enable cryptographic security. It is then a customer/operator + responsibility to ensure that the SNMP entity giving access to an + + + + + +Tesink Standards Track [Page 65] + +RFC 3592 SONET/SDH Objects September 2003 + + + instance of this MIB module is properly configured to give access to + the objects only to those principals (users) that have legitimate + rights to indeed GET or SET (change/create/delete) them. + +7.

Since changes in the signal state + lag the data to which they apply by 10 seconds, an implementation + which wishes to avoid making retroactive adjustments to the counts + must pass the the one-second statistics through a 10-second delay + line prior to updating any counters. That can be done by performing + the following steps at the end of each one second interval. + + i) Read near/far end line and path CV counts and alarm status flags + from the hardware. + + ii) Accumulate the CV counts for the preceding second and compare + them to the ES and SES threshold for the layer in question. + 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. + + + + + + + + + + + + + +Tesink Standards Track [Page 69] + +RFC 3592 SONET/SDH Objects September 2003 + + + +--------------------------------------------------------------+ + | 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. + + + +Tesink Standards Track [Page 70] + +RFC 3592 SONET/SDH Objects September 2003 + + + 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 + + + + + + +Tesink Standards Track [Page 71] + +RFC 3592 SONET/SDH Objects September 2003 + + + 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 + +Author's Address + + Kaj Tesink + Telcordia Technologies + 331 Newman Springs Road + P.O.
