OCU-DP Card User Screens and Settings
DIR
The Direction (DIR) setting allows users to specify where the BERT test signal should be
directed. The net (network) option transmits the test signal toward the Wide Area Network
(WAN). The user option directs the signal toward the attached CSU/DSU device over the
4-wire interface.
DATA
The DATA setting specifies whether the BERT test signal should be connected to the
pri (Primary) or the sec (Secondary) channel of the OCU-DP port. If there is no Secondary
channel associated with the OCU-DP port, the only option available is pri.
SYNC
The Synchronization (SYNC) field shows 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 (BE) 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 (ES) 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-
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 is an information-only field, there are no user-selectable parameters.
