65 ET BSC Measurement
1 65 ET BSC MeasurementThe ET BSC measurement is related to BSS7072 ET Downtime Statistics. The ET BSC measurement counters characterise the signal quality of each 2Mbit/s interface of an ET (exchange terminal) controlled by the BSC. The ET BSC measurement does not use an output interval of 15 or 30 minutes.
The CRC counters are updated only if the CRC mode of the ET is in use.
Measurement description
Measurement counters
• CRC times and error counters CRC times and errors are gathered into the following counters from the near and the remote end based on the ITU-T recommendation G.821.More detailed calculations can be made according to the recommendation.
• DisturbancesThese counters give the information on all functional disturbances detected by an ET.

Version: 2.1 NetAct name: AVAIL_TIME
Description: The total time that the connection has been available.
Counters 065002-065004 help detecting smaller disturbances in the connection. Note that those counters are more frequently updated than this counter.
Updated: The connection is unavailable when the bit error ratio (BER) of each second is worse than 1*(1/1000) for a period of ten consecutive seconds. A new period of available time begins with the first second of a period of ten consecutive seconds, each of which has a BER better than 1/1000.
If this counter is smaller than counter 065000, it indicates that there have been major problems in the connection.
