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.
