LAMP NAME
COLOR
STATE
REMARKS
LB
Red
Indicates that a loop-back test is in progress.
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 DRU 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 DRU has been
detected.
FRM
Red
Indicates that a frame loss due to the data from the DRU has been
detected.
MFRM
Red
Indicates that a multi frame loss due to the data from the DRU
has been detected.
RMT
Red
Indicates that the DRU has detected a frame loss and it has been
alerted from the remote office as an remote office alarm.
BLUE
Red
This lamp lights upon detecting a blue signal from the DRU.
(Indication of a state in which the DRU is under a local loop-
back testing)
PALM
Red
Power supply to Analog PB TEL/D
term
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
that circuit.
Lamp number can be
