Decoding the NCC 2020 CSU Status (STAT) LED Indicator
The STAT (CSU status) LED is a three-color indicator with six possible
states. This will be the only LED lit when the power-up self test fails.
Solid Green All OK
Flashing Green The NCC is being accessed by a thumbwheel
switch operator at the master NCC.
Solid Yellow An operator test is in progress (that is, a test
signal is currently being applied to the circuit by
the CSU).
Solid Red Any alarm.
Flashing Yellow and Red
Errors received during user initiated test.
Flashing Red Power-up self test failure.
Not Lit No power, blown fuse.
If an alarm state is caused by exceeding the performance monitoring
threshold, the alarm does not clear until the error in the selected intervals
falls below the threshold. This will be equal to one or more 15 minute
intervals.
Decoding the NCC 2020 Network (NET) LED Indicator LED
The NET (network) LED is a tri-state indicator with six states, as follows:
Solid Green A normal signal is being received from the
network (all OK).
Solid Yellow NCC is looped toward network via a line
loopback (LLB) or payload loopback (PLB) and
no errors received from the network.
Solid Red Continuous errors on the network (for example,
LOS, LOF, RAI, AIS).
