Internet Draft SONET/SDH Objects August 1993
2. Abstract
This memo defines an experimental portion of the Management
Information Base (MIB) for use with network management
protocols in TCP/IP-based internets. In particular, it
defines objects for managing Synchronous Optical
Network/Synchronous Digital Hierarchy (SONET/SDH) objects.
This document is a companion document with Definitions of
Managed Objects for the DS1/E1 and DS3/E3 Interface Types,
RFC1406 [14] and RFC1407 [13].
This memo specifies a MIB module in a manner that is both
compliant to the SNMPv2 SMI, and semantically identical to the
peer SNMPv1 definitions.
[Temporary Note: Upon progression of this specification as a
Proposed Standard, an SNMPv2 and an SNMPv1 version of this MIB
module will be made available to ease migration.]
This version differs from Version 2 (draft-ietf-cox-sonet-
mib-01.txt) as per the IETF Amsterdam meeting and subsequent
mailing list comments as follows:
- This MIB module is made compliant with SNMPv2 SMI.
- The precise use of ifTable as defined in RFC1213 and extended
in [12] has been specified.
- The object descriptors starting with "photonic" have been changed
to start with "medium" to accommodate both optical and electrical
cases.
- The General Table has been removed, and the objects were combined
with the objects in the Medium Table.
- An object sonetMediumType has been added to differentiate between
the two types of signals. Also, the sonetPathWidth and the
sonetVTWidth has been modified to handle SDH signals.
- The object sonetMediumLineType has been updated to handle other
medium types.
- The object sonetMediumValidIntervals has been modified.
- The Total tables have been removed.

3. The SNMPv2 Network Management Framework
The SNMPv2 Network Management Framework consists of four major
components. They are:
RFC 1442 [1] which defines the SMI, the mechanisms used for
describing and naming objects for the purpose of
management.
RFC 1213 [6] defines MIB-II, the core set of managed objects
for the Internet suite of protocols. Reference [12] defines
the evolution of the Interfaces Group of MIB II in terms of
extensions and precise applications of the objects.
RFC 1445 [4] which defines the administrative and other
architectural aspects of the framework.
RFC 1448 [5] which defines the protocol used for network
access to managed objects.
The Framework permits new objects to be defined for the
purpose of experimentation and evaluation.
This specification makes also use of:
RFC 1443 [2] which defines textual conventions for the
specification of managed objects.
RFC 1444 [3] which defines conformance statements for the
specification of managed objects.
T. Brown & K. Tesink (editors) Expires 3/1/94 [Page 4]
Internet Draft SONET/SDH Objects August 1993
4. Objects
Managed objects are accessed via a virtual information store,
termed the Management Information Base or MIB. Objects in the
MIB are defined using the subset of Abstract Syntax Notation
One (ASN.1) [7] defined in the SMI. In particular, each
object has a name, a syntax, and an encoding. The name is an
object identifier, an administratively assigned name, which
specifies an object type. The object type together with an
object instance serves to uniquely identify a specific
instantiation of the object. For human convenience, we often
use a textual string, termed the OBJECT DESCRIPTOR, to also
refer to the object type.
The syntax of an object type defines the abstract data
structure corresponding to that object type. The ASN.1
language is used for this purpose. However, the SMI RFC 1442
purposely restricts the ASN.1 constructs which may be used.
These restrictions are explicitly made for simplicity.
The encoding of an object type is simply how that object type
is represented using the object type's syntax. Implicitly
tied to the notion of an object type's syntax and encoding is
how the object type is represented when being transmitted on
the network. The SMI specifies the use of the basic encoding
rules of ASN.1 [8], subject to the additional requirements
imposed by the SNMP.
4.1. Format of Definitions
Section 6 contains contains the specification of all object
types contained in this MIB module. The object types are
defined using the conventions defined in the SMI, as amended
by the extensions specified in the SNMPv2 SMI.

Internet Draft SONET/SDH Objects August 1993
5. 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 (xx)
The definitions contained herein are based on the SONET/SDH
specifications in ANSI T1.105 and T1.106-1988 [9, 9a, 10] and
CCITT G.707, 708, 709, and G.783 [15-18].
5.1. Use of the ifTable
This section specifies how the MIB II interfaces group, as
defined in [12], 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.
Not all SONET/SDH equipment terminate all SONET/SDH layers.
For example, an 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 [6], as extended by [12], 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 [12], as follows:

5.5. 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 ANSI T1M1.3/92-005R1 [11]. The terminology used
in this document to describe error conditions on a SDH circuit
as monitored by a SDH system are from the CCITT G.783 [18].
Only the SONET Performance 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 [18]. If the definition in this document does not
match the definition in the ANSI T1M1.3/92-005R1 draft
document, the implementer should follow the definition
described in this document.
Section Loss Of Frame (Out of Frame Event)
An Out of Frame (OOF) event (or Severely Errored Frame
Event) is entered when four contiguous errored frame
alignment signals have been received. The OOF event is
cleared upon detecting two contiguous error-free frame
words. 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.
An Loss of Frame (LOF) defect is declared when an OOF
persists for a period of 3 milliseconds. The LOF defect
is cleared when the incoming signal remains continuously
in-frame for a period of 1 ms to 3 ms.
An LOF failure is declared when the LOF defect persists
for a period of 2 to 10 seconds. The LOF failure is
cleared when the LOF defect is absent for a period of
less than or equal to 20 seconds.
Loss of Signal
The Loss of Signal (LOS) defect is declared when no
transitions are detected on the incoming signal (before
T. Brown & K. Tesink (editors) Expires 3/1/94 [Page 9]
Internet Draft SONET/SDH Objects August 1993
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 to 10 seconds. The LOS failure is
cleared when the LOS defect is absent for a period of
less than or equal to 20 seconds. Declaration of LOS
failure clears any existing LOF failure. Clearing the
LOS failure allows immediate declaration of the LOF
failure if conditions warrant.
STS-Path Loss of Pointer
An 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 cleared 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.
A STS-Path LOP failure is declared when the STS-Path LOP
defect persists for a period of 2 to 10 seconds. A STS-
Path LOP failure is cleared when the STS-Path LOP defect
is absent for a period of less than or equal to 20
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 cleared 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 a period of 2 to 10 seconds. A VT LOP
failure is cleared when the VT LOP defect is absent for a
T. Brown & K. Tesink (editors) Expires 3/1/94 [Page 10]
Internet Draft SONET/SDH Objects August 1993
period of less than or equal to 20 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 cleared 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 to 10 seconds. A Line AIS
failure is cleared when the Line AIS defect is absent for
a period of less than or equal to 20 seconds. The Line
AIS failure declaration and clearing shall function
properly in the presence of a random BER of 10^-3 or
better.
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:
-- STS-Path AIS defect is detected as all ones in bytes
H1 and H2 in three contiguous frames.
-- The STS-Path AIS defect is cleared when a valid STS
Pointer is detected with the NDF set to "1001" (inverted)
for one frame, or "0110" (normal) for three contiguous
frames.
A STS-Path AIS failure is declared when the STS-Path AIS
defect persists for a period of 2 to 10 seconds. A STS-
Path AIS failure is cleared when the STS-Path AIS defect
is absent for a period of less than or equal to 20
seconds. The STS-Path AIS failure declaration and
clearing shall function properly in the presence of a
random BER of 10^-3 or better.
T. Brown & K. Tesink (editors) Expires 3/1/94 [Page 11]
Internet Draft SONET/SDH Objects August 1993
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 cleared 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 a period of 2 to 10 seconds. A VT-
Path AIS failure is cleared when the VT-Path AIS defect
is absent for a period of less than or equal to 20
seconds. The VT-Path AIS failure declaration and
clearing shall function properly in the presence of a
random BER of 10^-3 or better.
Line Remote Defect Indication
Line Remote Defect Indication (RDI) (aka Line FERF) is
generated by inserting the code "110" 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 five consecutive frames.
-- Line RDI defect is cleared when any code other than
"110" is detected in bits 6, 7, and 8 of the K2 byte in
five consecutive frames.
T. Brown & K. Tesink (editors) Expires 3/1/94 [Page 12]
Internet Draft SONET/SDH Objects August 1993
A Line RDI failure is declared when the incoming Line RDI
defects lasts for 2 to 10 seconds. The Line RDI failure
is cleared when no Line RDI defects are detected for
period equal to or less than 20 seconds.
STS-Path Remote Defect Indication
STS-Path RDI (aka STS-Path FERF) defect is generated
within 125 microseconds by the STS PTE upon detection of
an AIS or LOP defect. 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 five contiguous
frames.
-- Removal of STS-Path Remote Defect Indication is
detected by a "0" in bit 5 of the G1 byte in five
contiguous frames.
STS-Path RDI defect is cleared immediately by the STS PTE
when the AIS or LOP defect is no longer detected.
VT-Path Remote Defect Indication
VT Path RDI (aka VT Path FERF) defect is generated within
500 microseconds by the VT PTE upon detection of an AIS
or LOP defect. 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 five contiguous
frames.
-- VT-Path RDI defect is terminated when a "0" is
detected in bit 4 of the VT-Path Overhead byte (V5) for
five contiguous frames.
VT-Path RDI defect is terminated immediately by the VT
PTE when the AIS or LOP defect is no longer detected.
T1.105 is presently updating its requirements on the VT-
Path RDI and RFI. This document contains the current
requirements as much as possible.
T. Brown & K. Tesink (editors) Expires 3/1/94 [Page 13]
Internet Draft SONET/SDH Objects August 1993
VT-Path Remote Failure Indication
The VT-Path RFI is specified in ANSI T1.105. The RFI
failure is declared in the device within 5 ms of
detecting the incoming VT-Path RFI Signal. The following
criteria are specific to VT-Path RFI:
-- VT-Path Remote Failure Indication is generated by
setting bit 8 in the VT-Path Overhead byte (V5) to "1" in
ten contiguous VT superframes.
-- Removal of VT-Path Remote Failure Indication is
detected by a "0" in bit 8 of the V5 byte received for
ten contiguous VT superframes.
The Remote Failure Indication failure is cleared in the
device within 50 ms of the detection of the deactivation
of the incoming VT-Path Remote Failure Indication signal.
T1.105 may remove the VT-Path RFI signal and replace it
with the VT-Path RDI. See VT-Path RDI.
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., OOF, LOP, or AIS) at that
layer has occurred.
T. Brown & K. Tesink (editors) Expires 3/1/94 [Page 14]
Internet Draft SONET/SDH Objects August 1993
Severely Errored Seconds
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. Values of x vary depending on
the line rate and the Bit Error Rate. See Section 5.4
for values for x.
Severely Errored Framing Seconds
A Severely Errored Framing Second (SEFS) is a seconds
with containing one or more OOF 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 from the onset of 10
contiguous SESs, or the onset of the condition leading to
a failure. If the condition leading to the failure was
immediately preceded by one or more contiguous SESs, then
the SONET/SDH interface unavailability starts from the
onset of these SESs. Once unavailable, and if no failure
is present, the SONET/SDH interface becomes available at
the onset of 10 contiguous seconds with no SESs. Once
unavailable, and if a failure is present, the SONET/SDH
interface becomes available at the onset of 10 contiguous
seconds with no SESs, if the failure clearing time is
less than or equal to 10 seconds. If the failure
clearing time is more than 10 seconds, the SONET/SDH
interface becomes available at the onset of 10 contiguous
seconds with no SESs, or the onset period leading to the
successful clearing condition, whichever occurs later.
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.
A special case exists when the 10 or more second period
crosses the 900 second statistics window boundary, as the
foregoing description implies that the SES and UAS
counters must be adjusted when the Unavailable Signal
State is entered. Clearly, successive GETs of the
affected sonetPathIntervalSES and sonetPathIntervalUAS

Internet Draft SONET/SDH Objects August 1993
(for the Line and VT also) objects will return differing
values if the first GET occurs during the first few
seconds of the window. This is viewed as an unavoidable
side-effect of selecting the presently defined managed
objects as a basis for this memo.
Circuit Identifier
This is a character string specified by the circuit
vendor, and is useful when communicating with the vendor
during the troubleshooting process.
