Performance
Screens
The Performance screens display a detailed history of the error parameters that are
continuously monitored. 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 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 4-5.
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.
Element
Pressing the spacebar toggles this field for selection of either the NEAR or FAR
unit as the source of performance data or the target of commands. NEAR refers to
the unit the terminal is connected. FAR refers to the unit at the other end of the
network T1 span.
