OPE Green Indicates that the circuit card is operating normally.
N-OPE Red This circuit card is not in operation due to MB switch software.
LINK Green Indicates that a signal link with the DAP is established.
CRC Red Indicates that CRC error count is over the predefined threshold
value.
PCM Red Indicates that a failure of clock supply from the DAP has been
detected.
FRM Red Indicates that a frame loss due to the data from the DAP has

(Indication of a state in which the DAP is under a local loop-
back testing)
PALM Red Power supply to Analog PB TEL/Dterm is abnormal at more
than one circuit among No. 0 through No. 29 circuits.
BL Red Indicates that more than one circuit of No. 0 through No. 29 cir-
cuit is used.
BL0 – BL7 Red (1) When lit, indicates that the corresponding circuit is in active
state.
(2) When flickering, indicates that the corresponding circuit is
in Make Busy state or there is no system data available for
