BERP level carrier maintenance
The bit error rate performance (BERP) level performance tool is available at
the MAP terminal. This tool allows operating company personnel to measure
and monitor the bit error rate performance of the DMS-100 switch. This tool
also helps to identify defective components in the DMS switch. The tool
cannot test each path and change through a switch. Use the BERP tool to make
a random number of test calls, or bit error rate tests (BERT), to obtain the
BERP for a DMS switch. A test call is the transmission of a bit stream over a
path in the DMS switch for a specified duration of time. A test at the BERP
level consists of a number of test calls, or BERTs. To obtain a measure of the
performance of the DMS switch, extrapolate the results of the test calls. This
measure is based on the performance of the test calls.
To access BERP level carrier maintenance from the MAP terminal, type
>MAPCI;MTC;BERP
and press the Enter key.
The first step in a BERT is to set up a path. This path loops from an integrated
bit error rate tester (IBERT), back to this IBERT through a specified loopback
point in the path. When you set up a path, the IBERT transmits a known bit
