Performance
Screens The Performance screens display a detailed history of the continuously monitored
error parameters. The terminal interface provides display of near-end or far-end
performance data using the facility data link.
The unit is equipped with a dual set of performance data registers that hold line
statistics for both the telco and user. Each register set provides detailed status and
performance history for the network and DTE interfaces. The user register offers
individual resets.
The system has four Performance screens. The STANDARD 24 HOUR and the
ENHANCED 24 HOUR screens allow viewing the 24 -hour detailed performance
history of the T1 circuit. The only difference in the two screens is in the type of
performance data displayed. The STANDARD 24 HOUR screen is shown in
Figure 4-6.
The STANDARD 30 DAY and the ENHANCED 30 DAY screens allow viewing a
30-day history of a particular element’s performance. These screens reference
intervals by date rather than by time. To reach each of the four screen types, use
the spacebar to toggle the STANDARD 24 HOUR field. The other fields are
described as follows.
