Table 3-3. DTE Drop/Insert (DSX-1) Interface LEDs
Name Color Meaning
SIG
Green Monitors the signal being received from the DTE Drop/Insert
(DSX-1) interface.
ON: A recoverable signal is being received from the DTE
Drop/Insert (DSX-1) interface.
OFF: The signal cannot be recovered from the DTE Drop/Insert
(DSX-1) interface (a Loss of Signal condition exists).
OOF
Yellow Monitors Out Of Frame (OOF) conditions on the received DTE
Drop/Insert (DSX-1) signal.
ON: At least one OOF was detected on the signal during the
sampling period.
OFF: No OOFs were detected on the signal during the sampling
period.
ALRM
Yellow Indicates whether an alarm condition exists on the received DTE
Drop/Insert (DSX-1) signal.
ON: An alarm condition (LOS, LOF, EER, Yellow, AIS) exists on
the received DTE Drop/Insert (DSX-1) signal. Use the Device
Health and Status command to determine the alarm type.
OFF: No alarm condition exists on the DTE Drop/Insert (DSX-1)
interface signal.
PDV
Yellow Monitors Pulse Density Violations (PDV) on the received DTE
Drop/Insert (DSX-1) signal.
ON : At least one PDV was detected (and corrected) on the
received DTE Drop/Insert (DSX-1) signal during the sampling
period.
OFF: No PDVs were detected on the received DTE Drop/Insert
(DSX-1) signal during the sampling period.
BPV
Yellow Monitors Bipolar Violations (BPV) on the received DTE
Drop/Insert (DSX-1) signal.
ON: At least one BPV was detected (and corrected) on the
received DTE Drop/Insert (DSX-1) signal during the sampling
period.
OFF: No BPVs were detected on the received DTE Drop/Insert
(DSX-1) signal during the sampling period.
