DSI SS7MD Programmer’s Manual Issue 3
— For E1 operating modes, it is the number of errors detected in the frame alignment word.
— For T1 interfaces operating in D3/D4 frame format, it is the number of framing bit errors.
— For T1 interfaces operating in ESF format, it is the number of CRC6 errors.
Note: In general, the user should use the errored_seconds and severely_errored_seconds
parameters instead since these parameters provide normalized values that have the same
meaning for all modes of operation.
•
code_violations
A count of all the line code violations detected on the interface.
•
frame_slips
A count of the number of frame slips that have occurred on the interface.
•
oos_transitions
A count of the number of transitions from the in synchronization state to the out of synchronization
state.
•
errored_seconds
The number of seconds since the statistics were last reset during which the interface contained errors.
An errored second is any second during which the interface is out of synchronization, or there are frame
slips, bit errors, or line code violations.
•
severly_errored_seconds
The number of severely errored seconds since the statistics were last reset. A severely errored second is
a second during which the interface is out of synchronization or the bit error rate exceeds 1 in 1,000.
•
prbs_status
The status of Pseudo Random Bit Sequence (PRBS) indications.
- 1 = PRBS is valid, the counts are correct.
- 3 = PRBS sequence is not synchronized.
