Revision 01
(12)
nonUrg-ValidSignalAbsent-OpticalLow: Either no valid signal is present on the
input to the transmitter or received by the receiver and optical detector of
receiver is reporting that the optical input signal is approaching its minimum, or
has exceeded its, allowable signal strength.
NOTE:
Detectors can vary in their
reporting of optical low state. It is recommended to confirm that the received
signal is error free if an Optical Low alarm has been raised.
(13)
urgent-1-OpticalFail-nonUrg-validSignalAbsent-opticalLow: Transmitter laser has
failed and no valid signal has been received by the receiver and optical detector
of receiver is reporting that the optical input signal is approaching its minimum,
or has exceeded its, allowable signal strength.
NOTE:
Detectors can vary in their
reporting of optical low state. It is recommended to confirm that the received
signal is error free if an Optical Low alarm has been raised.
(14)
urgent-2-OpticalFail-nonUrg-validSignalAbsent-opticalLow: Not applicable to the
IRT-6630-DTR.
(15)
urgent-1-2-OpticalFail-nonUrg-ValidSignalAbsent: Both transmitter laser has
failed and optical input to the receiver’s detector is below its minimum threshold
or has failed and no valid signal is present on the input to the transmitter.

irt663xDxxSettingsTable:
A table containing configuration settings for all IRT-6630-DTR cards at this node.
controlMode
- An indication of the control settings made as per the PCB DIP switch setting:
(0)
dashboardSNMP: Card settings can be controlled via DashBoard™ or SNMP.
(1)
pcbSwitches: Card settings as per DIP switch settings only.
(2)
lockedtoDashboardSNMP: Lock module to DashBoard™ or SNMP control –
overrides SW1-7 position. Note that SW1-7 must be initially ON to be able to set
to Lock to SNMP mode. To release send either a (0) or (1).
ioAlarmTrapEnable
- An indication and control of Trap enable/disable function of input/output alarms:
(0)
ioAlarmTrapDisable: Disable input/output alarm Traps.
(1)
ioAlarmTrapEnable: Enable input/output alarm Traps.
reset
- Unit reset control:
(0)
normal: when queried reset control returns a ‘normal’ state.
(1)
reset: system reset causes a reset of the card.
autoChangeOver
- Enable or Disable Automatic Changeover to switch Tx optical output from primary (IN 1)
to secondary (IN 2) input on loss of valid primary input (if secondary input is both
present and valid):
(1)
disable: Automatic Changeover mode disabled.
(2)
enable: Automatic Changeover mode enabled.
monitorPort
- Sets the signal source for BNC OUT 1:
(0)
receiverInput: OUT 1 port outputs the received signal.
(1)
transmitterOutput: OUT 1 port outputs the transmitted signal.
(2)
transmitterOutput: Not applicable to IRT-6630-DTR. Defaults back to
receiverInput (0).
(3)
cableInputs: Not applicable to IRT-6630-DTR. Defaults back to transmitterOutput (1).
keepAliveTx1
- A substitution of a 54 MHz signal in place of no input signal to keep the optical link active
at the receiver end:
(1)
enable: Keep Alive signal enabled.
(2)
disable: Keep Alive signal disabled.
keepAliveTx2
-
Not applicable to the IRT-6630-DTR.
optical1TrapEnable
- An indication and control of Trap enable/disable function of the transmitter laser state:
(0)
disable: Disable laser Trap alarms.
(1)
enable: Enable laser Trap alarms.
optical2TrapEnable
- An indication and control of Trap enable/disable function of the receiver input state:
(0)
disable: Disable receiver Trap alarms.
(1)
enable: Enable receiver Trap alarms.
