88..11..33..33 Alarms and ErrorsAlarms and Errors
Touching the lower summary box in the status area of the Ports SetupPorts Setup screen
displays the status shown below.
This screen contains detailed alarm and error information related to the
CPRI/OBSAI interface. Status is indicated by the use of colored Lamp icons.
RemoteRemote and LinkLink are displayed only when the content is set to CPRI.
Alarms
Signal lossSignal loss: This lit in red when the optical signal is not detected.
LOSLOS: Loss of Signal.
For 614.4 to 9830.4 Mbps, this lit in red when at least sixteen 8B/10B
violations occur among a whole hyperframe.
For 10137.6 Mbps, this lights in red when at least four 64B/66B sync header
code violations occur among a whole hyperframe.
LOFLOF: Loss of Frame.
This lit in red when the hyperframe alignment cannot be achieved or is lost
based on CPRI specification.
LSSLSS: Loss of Signal Synchronization.
This lit in red when 10 % or larger bits in the test pattern have occurred errors.
Errors
LCVLCV: Line Code Violations (8B/10B decoding)
Received 10 bit sequence is not defined in 8B/10B conversion table.
SHVSHV: Sync Header Violation (64B/66B decoding)
K30.7K30.7: Invalid 10B code (8B/10B decoding)
