4.2.3 Framer Parameters
> Bit Error Rate (BER)
EX7100 provides an indicator of BER performance. This should not be used as an
accurate measure of BER due to the lack of overhead bandwidth available. The system is
able to process, and thus indicate a BER of: <1x10
-6
(normal operation), 1x10
-5
, 1x10
-4
,
and 1x10
-3
.
