RLSD
The Receive Level Signal Detect (RLSD) option allows you to define whether the RLSD
control lead should be held on (high) or off (low). The third option is norm (normal) which
means that RLSD will behave as described in Table 2-3.
SYNC
The Synchronization (SYNC) field tells you if the integrated BERT has achieved
synchronization either with itself via a remote loopback or with the remote test equipment.
Since this is an information-only field, there are no user-selectable parameters.
BE
The Bit Error field shows the total number of bit errors logged. Since this is an
information-only field, there are no user-selectable parameters.
ES
The Errored Seconds field shows the total number of seconds in which any errors were
detected. Since this is an information-only field, there are no user-selectable parameters.
SES
The Severely Errored Seconds (SES) field shows the total number of seconds in which the bit
error rate exceeded one bit per thousand (1 x 10
-3
). Since this is an information-only field, there
are no user-selectable parameters.
CSES
The Consecutive Severely Errored Seconds (CSES) field is triggered by the occurrence of ten
consecutive Severely Errored Seconds. Once triggered, the CSES field will increment (by
one) for each elapsed second until the system logs ten consecutive non-Severely Errored
Seconds. Since this it an information-only field there are no user-selectable parameters.
OSS
The Out of Synchronization Seconds field shows the number of seconds that the SRU BERT
has been out of synchronization. Since this is an information-only field, there are no
user-selectable parameters.
