Stream Rate frame
This frame indicates the transmitted and received ATM bitrate
in kbps.
AU-4 Pointer checkbox
For SDH network operation the AU-4 pointer can be enabled or
disabled. The default setting is disabled (Sonet operation).
SDH frame
This frame displays the following fl ags:
LOS
= Loss of Signal
The LOS alarm indicates that there are no transitions occurring
in the signal received by the network element.
LOF
= Loss of Frame
The receiver raises the LOF alarm when an OOF condition
persists for 3 ms or longer. It clears the alarm when it receives
a valid signal for 3 ms.
OOF
= Out of Frame
An OOF alarm occurs when one or more bit errors in each
framing pattern are detected for four consecutive frames.
LOP
= Loss of Pointer
A network element transmits a LOP alarm downstream when it
receives 8 consecutive frames containing an invalid pointer, or
8 consecutive New Data Flags (NDF’s other than in a
concatenation indicator ).
AIS-L
= Alarm Indication Signal-Line
RDI-L
= Remote Defect Indicator-Line
AIS-P
= Alarm Indication Signal-Path
RDI-P
= Remote Defect Indicator-Path
Alarm Indication Signals and Remote Defect Indicators are
mechanisms used to report network faults.
Clock Rec.
This fl ag indicates if the clock recovered from the incoming
stream is close enough to the frequency of the reference
oscillator.
