Ethernet BERT Test
108 AXS-200/805/855
Unidirectional BERT testing is performed whereby the test stream is
transmitted from the local module to a remote device in loopback, and the
test stream is received back and locally analyzed. The results are reported
at the local end.
Bidirectional BERT testing is composed of two independent tests where
traffic transmitted from one end will be analyzed at the other end. Test
synchronization between 2 units is performed on a best-effort basis. Any
alarms/errors due to incorrect synchronization can be cleared while the
test is running. The test results for each direction are reported only at the
receive end. There is no exchange of results between test units. The local
and remote modules can be either an AXS-200/855 Multi Protocol Test Set
or FTB-8510/8510B/8510G.
The BERT menu offers the following structure:
