PA-DAIU Lamp Indication Reference Table
LAMP NAME COLOR STATE REMARKS
OPE
Green Indicates that the circuit card is operating normally.
OFF Indicates that the circuit card is in make-busy state.
LINK
Green
Indicates that Layer 2 and Layer 3 signal links with the DRU/DAU are
established.
Indicates that a remote loop-back test has completed normally.
Flash
(60INT)
Indicates that Layer 2 signal link with the DRU/DAU is established, and
Layer 3 signal link with DRU/DAU is not established.
OFF
Indicates that Layer 2 and Layer 3 signal links with the DRU/DAU are
not established.
LB Red Indicates that a remote or local loop-back test is in-progress.
CRC Red
Indicates that bit error rate (CRC error count) exceeds the defined
threshold value.
PCM Red
Indicates that a failure of clock supply from the DRU/DAU has been de-
tected.
FRM Red
Indicates that a Frame Loss due to the data from the DRU/DAU has
been detected.
MFRM Red
Indicates that a Multi-Frame Loss due to the data from the DRU/DAU
has been detected.
AIS Red
Lights on detecting a Blue Signal from the DRU/DAU. (This indication
means the DRU/DAU is under a local loop-back test.)
RMT Red
Indicates that the DRU/DAU has detected a Frame Loss and it has been
alerted from the remote office as a Remote Office Alarm.
PALM Red
The power supply to a Dterm is abnormal at more than one circuit in
Circuit Numbers 0~29.
BL00 ~ BL29
Green Indicates that the corresponding circuit is in active state.
Flash
(60INT)
Indicates that the corresponding circuit is in make-busy state or there
is no system data available for that circuit.
OFF Indicates that the corresponding circuit is in idle state.
