Description
Field
Any alarms detected by the controller are displayed
here. Possible alarms are as follows:
•
Transmitter is sending remote alarm.
•
Transmitter is sending AIS.
•
Receiver has loss of signal.
•
Receiver is getting AIS.
•
Receiver has loss of frame.
•
Receiver has remote alarm.
•
Receiver has no alarms.
Transmitter is sending RAI
Framing type on the controller. Values are G.751 and
G.832.
Framing
Line coding format on the controller.
Line Code
Clock source on the channelized controller. Values
are internal and line.
Clock Source
Shows the current accumulation period, which rolls
into the 24-hour accumulation every 15 minutes. The
accumulation period is from 1 to 900 seconds. The
oldest 15-minute period falls off the back of the
24-hour accumulation buffer.
Data in current interval (seconds elapsed)
Line Code Violations (LCVs) is a count of both
Bipolar Violations (BPVs) and Excessive Zeros
(EXZs) that occur over the accumulation period. An
EXZ increments the LCV by one regardless of the
length of the zero string.
Line Code Violations
For all DS3 applications, a P-bit coding violation
(PCV) error event is a P-bit parity error event. A P-bit
parity error event is the occurrence of a received P-bit
code on the DS3 M-frame that is not identical to the
corresponding locally calculated code.
P-bit Coding Violation
For C-bit parity and SYNTRAN DS3 applications,
the C-bit coding violation (CCV) is the count of
coding violations reported by the C-bits. For C-bit
parity, it is the count of CP-bit parity errors that occur
during the accumulation interval. For SYNTRAN, it
is a count of CRC-9 errors that occur during the
accumulation interval.
