9-12 High Speed Data Ports
Model No. Running Head
SES
The Severely Errored Seconds (SES) field indicates the total number of seconds in which the
bit error rate exceeded one bit per thousand (1 x 10
- 3
). This is an information-only field; it is
not user-configurable.
CSES
The Consecutive Severely Errored Seconds (CSES) field is triggered by the occurrence of ten
consecutive Severely Errored Seconds. Once triggered, this field will increment (by one) for
each elapsed second until the system logs ten consecutive non-Severely Errored Seconds. This
is an information-only field; it is not user-configurable.
OSS
The Out of Synchronization Seconds (OSS) field indicates the number of seconds that the
HSU BERT has been out of synchronization. This is an information-only field; it is not
user-configurable.
BER
The Bit Error Rate (BER) field indicates the rate at which errors are being logged. The system
calculates BER by dividing the number of bit errors (BE) by the total number of bits
transmitted during the test. This is an information-only field; it is not user-configurable.
ELAP
The Elapsed time (ELAP) setting indicates the running tally of the total number of seconds
during the test. This is an information-only field; it is not user-configurable.
LB ST
The Loopback State (LB ST) field indicates whether there are any remotely-initiated
loopbacks currently active on the HSU port. This field displays latching loopbacks initiated
from a remote device via in-band loop-up codes. In addition to none, the system will display
V.54 or FT1 (fractional T1). This is an information-only field; it is not user-configurable.
