DS1 Node Timing Module (NTM-DS1)
Front Panel Indicators
•
RUN
LED Flashing Green indicates that the NTM is starting up and loading
required files.
LED ON Green indicates that the NTM start-up is complete, all required files are
loaded, and the NTM is active in the system.
•
FLT
(Fault) LED ON Red continuously during start-up is normal.
LED ON Red continuously after start-up indicates that the NTM has failed.
•
TX RC/DR
(Transmitting Received Clock/Derived Clock)
LED ON Green indicates that the NTM has been initialized, is configured, and is
transmitting properly.
•
TA RC
(Transmitting AIS Received Clock)
LED ON Red indicates that the NTM is transmitting an alarm indication signal
because it is initializing and/or waiting for its configuration from the Slot-0
Controller.
•
TA DR
(Transmitting AIS Derived Clock)
LED ON Red indicates that the NTM is transmitting an alarm indication signal
because it is initializing and/or waiting for its configuration from the Slot-0
Controller. It may also indicate that both line reference clocks have failed.
•
RA RC/DR
(Receiving AIS Received Clock/Derived Clock)
LED ON Red indicates that the NTM is receiving an alarm indication signal.
•
LS RC/DR
(Receiving LOS Received Clock/Derived Clock)
LED ON Red indicates that the NTM is detecting a loss of signal alarm condition.
•
OF (RC/DR)
Receiving OOF (Received Clock/Derived Clock)
LED ON Red indicates that the NTM is detecting an out of frame alarm condition.
•
ER (RC/DR)
Receiving BER (Received Clock/Derived Clock)
LED ON Red indicates that the NTM is detecting a bit error rate alarm condition.
•
LOCK
(Locked) LED ON Yellow indicates that the NTM oscillator is locked to
the selected reference timing source.
•
PRI
(Primary) LED ON Yellow indicates that the NTM has been configured as
the primary transmit reference timing source of the node.
Front Panel Connectors
•
RC-IN
is a DB-15 female connector that accepts BITS signals from an external
clock system.
•
DR-OUT
is a DB-15 female connector that sends derived BITS signals to an
external clock system.
