PRISM 3000 4-4 Terminal Operation
NOTE: The parameters shown on the Alarms Screen
are updated at five second intervals.
Power Loss Seconds: This field displays the number of
seconds that the element has been without power since this
value was last cleared.
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.
4.4 Performance Screens
The ‘Performance’ screens display a detailed history of the
error parameters that are continuously monitored. The ter-
minal interface provides display of near end or far end per-
formance 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 ‘ STAN-
DARD 24 HOUR ’ and the ‘ ENHANCED 24 HOUR ’ screens
allow the user to view the 24-hour detailed performance his-
tory of the T1 circuit. The only difference in the two screens
is in the type of performance data displayed. The ‘
STAN-
DARD 24 HOUR ’ screen is shown in Screen 4-4 .
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 two-part field determines which section of the
circuit is presently displayed by toggling the <spacebar>.
Telco registers are for viewing only and may not be
changed. The four options are:
[ USER ] [ NET ] – Display the user performance registers
for the network.
[ USER ] [ DTE ] – Display the user performance registers
for the T1 DTE.
[ TELCO ] [ NET ] – Display the telco performance registers
for the network.
[ TELCO ] [ DTE ] – Display the telco performance registers
for the T1 DTE.
Error Events: This field displays the running total of ESF
error events for the circuit selected in ‘
Element ’ 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
following 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
