INSTRUMENT
DESCRIPTION
combined NIU/Performance Monitor equip-
ment for the T1 span statistics it recorded.
When this mode is enabled, all unrelated func-
tions are disabled, framing is set to T1 ESF,
and the transmitted pattern is set to 1:1. The
SMARTNIU mode enables three functions;
Query, Clear Results, and Set Clock.
PATTERN Switch
When the SMARTNIU mode is enabled, the follow-
ing switch selections are available:
RESULTS — The RESULTS position activates
the Query function of the SMARTNIU mode,
which queries, retrieves, and stores the perfor-
mance monitor statistics. When RESULTS is
selected, the
RCVD , LOOP CODES , LOOP UP ,
LOOP DOWN , and ERR INS switches are dis-
abled. One complete set of performance moni-
tor statistics can be stored at a time, so
previously stored statistics are cleared from
the T-BERD 107A by the next query.
SETUP — The SETUP position allows the
T-BERD 107A to either clear the recorded
statistics from the NIU/Performance Monitor or
set the NIU/Performance Monitor time and date
to match the T-BERD 107A’s time and date.
The Clear Results function is performed after
the results are retrieved using the CLEAR NIU
selection. The Set Clock function is performed
using the SET CLOCK position.
