Bursty Errored Second.
A 1 indicates the receive framer
detected a bursty errored second. The events that can cause an
errored second are provisionable for DS1 links in
Table 317 on
page 249
and for CEPT links in
Table 320 on page 250
. The
severely errored second threshold is provisionable; DS1-SF
links in
Table 314 on page249
, DS1-ESF links in
Table 316 on
page 249
and CEPT links in
Table 319 on page250
.
BES is not valid in any CEPT mode.
Note:
The SES threshold must always be greater than the ES
threshold because BES lies in between (i.e., ES < BES <
SES).
Errored Second (G.826 Annex B).
A 1 indicates the receive
framer detected an errored second. The events that can cause
