Configuration 3-5 PRISM 3101/3102
Reset Alarm Registers: Pressing <return> on (RESET)
zeros the value of all Current alarm parameters, but does not
affect 24-hour or 30-day performance registers.
Performance Screen
The Performance screen (Figure 3-8) display a detailed his-
tory of the error parameters that are continuously monitored.
The terminal interface provides a 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 interface.
The system has four Performance screens. The STANDARD
24 HOUR and the ENHANCED 24 HOUR screens allow
the user 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 3-8.
The STANDARD 30 DAY and the ENHANCED 30 DAY
screens allow the user to view a 30-day history of a particu-
lar 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 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 per-
formance registers. Telco registers are for viewing only and
may not be changed. The options are:
[USER] [NET] – Display the user performance registers for
the network.
[TELCO] [NET] – Display the telco performance registers
for the network.
Error Events: This field displays the running total of ESF
error events for the circuit selected in the Element field and
is applicable only when Target is set to [USER]. This count
accumulates until it reaches 65535 or is reset by pressing
<return> with the (RESET) field highlighted.
Reset Performance Registers: This field allows the ele-
ment registers to be reset and may only be used when the
Target field is set to [USER]. If <return> is pressed, the fol-
lowing warning appears:
DELETE ALL PERFORMANCE DATA?
(NO!) (YES)
To exit this screen without performing the reset function,
press <return> with NO selected. To proceed with the reset
function, press <return> on YES. All values for the chosen
register set (NET or DTE) are then reset to zero.
[Standard 24 Hour]: Toggling this field with the <space-
bar> steps through the four available performance screens.
The remainder of the fields in the Performance screen are
for display only. They are defined as follows:
Status: Displays the selected T1 line status derived from
the type (or absence) of errors in the received data. This sta-
tus represents the immediate state of the received T1 signal
and is not related to the alarm thresholds. This field shows
