Figure 4-4 Performance Screen
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 T1 DTE interfaces.
The system has four Performance screens. The STANDARD 24 HOUR and the
ENHANCED 24 HOUR screens allow you to view 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 4-4.
The STANDARD 30 DAY and the ENHANCED 30 DAY screens allow you to
view 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.
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 to which the terminal is connected. Far refers to the unit at the other end
of the network T1 span.
Target This field selects the display of User or Telco performance registers. Telco
registers are for viewing only and may not be changed.
USER NET – Display the user performance registers for the network.
USER DTE - Display the user performance registers for the DTE.
TELCO NET – Display the telco performance registers for the network.
