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
