interface. CoIfWavelengthEntry .1.3.6.1.4.1.9.10.66.1.2.1.1 |
coIfDwdmFrequencyThe nominal central frequency associated with this interface,
in GHz.
This object is instantiated for interfaces with
coIfTypeExtn value of 'wdmChannel' and

for optoelectronic interfaces that originate or terminate
DWDM wavelengths, including some of the interfaces with
coIfTypeExtn value of 'opticalTransponder'.rw CoDwdmFrequency UNITS "GHz" .1.3.6.1.4.1.9.10.66.1.2.1.1.1 |
coIfDwdmChannelGroup OBJECT IDENTIFIER .1.3.6.1.4.1.9.10.66.1.3 |
coIfDwdmChannelGroupTableThis table contains information about interfaces representing
groups of DWDM channels. This includes interfaces with
coIfTypeExtn value of 'wdmChannelGroup'. SEQUENCE OF CoIfDwdmChannelGroupEntry .1.3.6.1.4.1.9.10.66.1.3.3 |
coIfDwdmChannelGroupEntryAn entry contains information about one interface that
represents a group of DWDM channels. The group can be
described as a specified set of DWDM frequencies, or as the
group of all DWDM frequencies except for those in a specified
set.
If a frequency is included in a DWDM channel group, this does
not necessarily indicate that there is a signal present at that
frequency. It indicates that if a signal is present at that
frequency, then that signal is included in this DWDM channel
group. CoIfDwdmChannelGroupEntry .1.3.6.1.4.1.9.10.66.1.3.3.1 |
coIfDwdmChannelGroupMinFrequencyThe lowest frequency represented in the bitmap specified in
coIfDwdmChannelGroupBitmap, i.e., the frequency represented by
bit 0 of octet 1 of coIfDwdmChannelGroupBitmap.rw CoDwdmFrequency UNITS "GHz" .1.3.6.1.4.1.9.10.66.1.3.3.1.1 |
coIfDwdmChannelGroupSpacingThe difference in frequency between successive bits in
coIfDwdmChannelGroupBitmap. This is typically the frequency
difference between adjacent channels in the DWDM system.rw Unsigned32 .1.3.6.1.4.1.9.10.66.1.3.3.1.2 |
coIfDwdmChannelGroupBitmapLogicThis object indicates whether coIfDwdmChannelGroupBitmap
identifies channels included in the channel group, or whether
it identifies channels excluded from the channel group.
When the value of this object is 'carried', then the channel
group is composed only of those channels for which the value of
the corresponding bit in coIfDwdmChannelBitmap is one.
When the value of this object is 'blocked', then the channel
group is composed of all channels except those for which the
value of the corresponding bit in coIfDwdmChannelBitmap is
one. Channels that are not identified in coIfDwdmChannelBitmap
are included in the channel group.rw Enumeration .1.3.6.1.4.1.9.10.66.1.3.3.1.3 |
coIfDwdmChannelGroupBitmapThe DWDM channel bitmap that indicates those channels that
are included or excluded (depending on the value of
coIfDwdmChannelBitmapLogic) from the DWDM channel group.
If a frequency is included in a DWDM channel group, this does
not necessarily indicate that there is a signal present at that
frequency. It indicates that if a signal is present at that
frequency, then that signal is included in this DWDM channel
group.
Bit zero of octet one corresponds to the lowest channel
(representing the frequency identified by
coIfDwdmChannelGroupMinFrequency), bit one of octet one
corresponds to the lowest plus one channel (representing
the frequency obtained by adding the values of
coIfDwdmChannelGroupMinFrequency and
coIfDwdmChannelGroupSpacing), and so on.
When the value of coIfDwdmChannelBitmapLogic is 'carried',
then channels included in the channel group will have the
corresponding bit set to one in the bitmap. Bits that are set
to zero represent channels that are excluded from the channel
group. Channels that are not represented in the bitmap are
also excluded from the channel group.
When the value of coIfDwdmChannelBitmapLogic is 'blocked',
then channels excluded from the channel group will have the
corresponding bit set to one in the bitmap. Bits that are set
to zero represent channels that are included in the channel
group. Channels that are not represented in the bitmap are
also included in the channel group.rw OCTET STRING .1.3.6.1.4.1.9.10.66.1.3.3.1.4 |
coIfXcvrGroup OBJECT IDENTIFIER .1.3.6.1.4.1.9.10.66.1.4 |
coIfXcvrTableThis table contains objects to control transceivers (lasers
and optical receivers) at optoelectronic interfaces. SEQUENCE OF CoIfXcvrEntry .1.3.6.1.4.1.9.10.66.1.4.1 |
coIfXcvrEntryAn entry contains objects for control of a transceiver at an
optoelectronic interface. CoIfXcvrEntry .1.3.6.1.4.1.9.10.66.1.4.1.1 |
coIfXcvrLaserAdminStatusThe desired state of the laser on this interface.
This object differs from ifAdminStatus in the IF-MIB, since
in some cases setting ifAdminStatus to 'down' causes an alarm
indication to be transmitted, rather than shutting down the
laser. When this object is set to 'down', ifOperStatus in the
IF-MIB goes to the 'down' state, and the laser is shut down.
In order to administratively enable an interface, both
ifAdminStatus in the IF-MIB and this object must be set to
'up'.rw Enumeration .1.3.6.1.4.1.9.10.66.1.4.1.1.1 |
coIfXcvrLaserOperStatusThis object indicates the current operational status of the
laser on this interface.
'transmitting': The laser is on.
'degraded': The laser is on, but there is a fault that causes
it to transmit in a degraded manner.
'down': The laser is shut down, either because of error
conditions or because it has been administratively
disabled. This state indicates that the laser is shut down
due to conditions other than Laser Safety Control or
Forward Laser Control.
'lscDown': The laser is shut down due to Laser Safety Control
(LSC) mechanisms such as Automatic Laser Shutdown (ALS),
i.e., due to a fault in the receive direction at this
interface.
'flcDown': The laser is shut down due to Forward Laser Control,
i.e., due to a fault on the cross-connected interface.
'unknown': The operational status of the laser cannot be
determined.
If the value of coIfXcvrLaserAdminStatus is 'down', then this
object also indicates 'down'. If coIfXcvrLaserAdminStatus is
set to 'up', then the value of this object should change to
'transmitting' if the laser is functioning properly.ro Enumeration .1.3.6.1.4.1.9.10.66.1.4.1.1.2 |
coIfXcvrMinLaserFrequencyThe lowest frequency represented in the bitmap specified in
coIfXcvrLaserFrequencyBitmap, i.e., the frequency represented
by bit 0 of octet 1 of coIfXcvrLaserFrequencyBitmap.
A value of zero signifies that the laser on this interface is
uncolored and that coIfXcvrLaserFrequencyBitmap does not
apply.rw CoDwdmFrequencyOrZero UNITS "GHz" .1.3.6.1.4.1.9.10.66.1.4.1.1.3 |
coIfXcvrLaserFrequencySpacingThe difference in frequency between successive bits in
coIfXcvrLaserFrequencyBitmap. This is typically the frequency
difference between adjacent channels in the DWDM system.rw Unsigned32 .1.3.6.1.4.1.9.10.66.1.4.1.1.4 |
coIfXcvrLaserFrequencyBitmapThis bitmap indicates the DWDM channel frequencies supported
by the tunable laser on this interface.
Bit zero of octet one corresponds to the lowest channel
(representing the frequency identified by
coIfXcvrMinLaserFrequency), bit one of octet one corresponds
to the lowest plus one channel (representing the frequency
obtained by adding the values of coIfXcvrMinLaserFrequency
and coIfXcvrMinLaserFrequencySpacing), and so on.
The frequencies supported by the tunable laser have the
corresponding bit set to one in the bitmap. Bits that are set
to zero represent frequencies that are not supported by the
tunable laser. The frequencies that are not represented in the
bitmap are also not supported by the tunable laser.ro OCTET STRING .1.3.6.1.4.1.9.10.66.1.4.1.1.5 |
coIfXcvrForwardLaserControlThis object is used to enable or disable Forward Laser Control
(FLC) on this interface. If Forward Laser Control is enabled,
the laser is automatically shut down when the receive direction
of the cross-connected interface is in an alarm condition.rw Enumeration .1.3.6.1.4.1.9.10.66.1.4.1.1.6 |
coIfXcvrLaserSafetyControlThis object is used to enable or disable Laser Safety Control
(LSC) mechanisms such as Automatic Laser Shutdown (ALS) on this
interface. Laser Safety Control mechanisms are used to
automatically shutdown the output power of laser transmitters
when potentially hazardous conditions such as fiber breaks or
unplugged optical connectors are detected.rw Enumeration .1.3.6.1.4.1.9.10.66.1.4.1.1.7 |
coIfXcvrLSCProtocolThis object identifies the Laser Safety Control protocol that
is applied when coIfXcvrLaserSafetyControl is set to 'enable'.
'proprietary': Indicates that the Laser Safety Control protocol
is proprietary.
'g664': Indicates the Automatic Laser Shutdown (ALS) protocol
specified in ITU-T Recommendation G.664.rw Enumeration .1.3.6.1.4.1.9.10.66.1.4.1.1.8 |
coIfXcvrLSCRestartModeThis object selects the mechanism used to restore transmission
after the fiber has been repaired or reconnected.
'automaticRestart': This mode selects automatic restart of the
laser by periodically transmitting restart pulses. The
period between restart pulse transmissions is specified by
coIfXcvrLSCPulseReptitionTime.
'manualRestart': This mode selects manual restart of the laser.
After the fiber has been repaired or reconnected, the
coIfXcvrLSCManualRestart object should be used to trigger
transmission of a restart pulse.rw Enumeration .1.3.6.1.4.1.9.10.66.1.4.1.1.9 |
coIfXcvrLSCManualRestartThis object initiates laser activation when the laser is shut
down due to Laser Safety Control.
When the value is set to 'restart', transmission of a restart
pulse of length coIfXcvrLSCPulseLength is triggered.
When this object is set to 'restartForTest', transmission of a
restart pulse of length coIfXcvrLSCTestPulseLength is
triggered. Before setting this object to 'restartForTest',
specific care must be taken to assure connectivity to avoid
exposure to hazardous optical levels.
When the value is set to 'noop', no operation is performed.
When read, the value 'noop' is returned.
Manual restart can only be activated when the value of
coIfXcvrLaserOperStatus is 'lscDown'.rw Enumeration .1.3.6.1.4.1.9.10.66.1.4.1.1.10 |
coIfXcvrLSCPulseLengthThis object specifies the length of restart pulses used to
restore transmission when a Laser Safety Control protocol is
activated.rw Unsigned32 .1.3.6.1.4.1.9.10.66.1.4.1.1.11 |

are transmitted when coIfXcvrLSCManualRestart is set to
'restartForTest'.rw Unsigned32 .1.3.6.1.4.1.9.10.66.1.4.1.1.12 |
coIfXcvrLSCPulseRepetitionTimeThis object specifies the delay interval between transmissions
of restart pulses, when coIfXcvrLSCRestartMode is set to
'automaticRestart' and coIfXcvrLaserOperStatus indicates
'lscDown'.rw Unsigned32 .1.3.6.1.4.1.9.10.66.1.4.1.1.13 |
