Trib built in link test applied. This is a warning alarm.
The built-in BER test has been applied to a trib.
To remove the alarm, deselect the test.
In the link test mode traffic on the selected tributary is replaced by a standard
15-1
2 pseudo random bit sequence (PRBS) test pattern. Link BER from the
received pattern can then be estimated. The test is normally run with the remote
radio in loopback. Counters are provided for:
a) The number of errored bits while synchronized to the PRBS
b) The number of error free bits while synchronized to the PRBS
This test can only be applied to one tributary at a time.
