13-14 OWAN Ports
Model No. Running Head
OSS
The Out of Synchronization Seconds (OSS) field shows the number of seconds that the WAN
BERT has been out of synchronization. Since this is an information only field, there are no
user selectable parameters.
BER
The Bit Error Rate (BER) field shows 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. Since this is an information only field, there are no user selectable
parameters.
ELAP
The Elapsed time setting shows the running tally of the total number of seconds during the
test. Since this is an information only field, there are no user selectable parameters.
LB ST
The Loopback State setting changes when a WAN unit is both present and operational. This
includes loopbacks caused by commands from remote devices as well as loopbacks caused by
local settings. The field will show payld (payload loopback) when the entire signal, excluding
the framing bit, is looped back. The field will show line (line loopback) when the entire signal
is looped back towards the network. This field will show local (local loopback) when the
entire signal is looped back to the ports own transmitter. It will show none if the OWAN port
is not in loopback.
