Terminal Operation 4-5 PRISM 3021
Performance Screens
The performance screens display a detailed history of con-
tinuously monitored error parameters. The terminal interface
provides a display of near-end and 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 six performance screens. The E1 24 Hour,
Standard 24 Hour, and Enhanced 24 Hour screens allow
viewing the 24-hour detailed performance history of the E1
circuit. The only difference in the three screens is the type of
performance data displayed. The E1 24 Hour screen is
shown in Figure 4-7.
The E1 30 Day, Standard 30 Day, and Enhanced 30 Day
screens allow viewing a 30-day history of a particular ele-
ment’s performance. These screens reference intervals by
date rather than by time.
To reach each of the six screen types, toggle the spacebar at
the E1 24 Hour Field. The fields common to all performance
screens are described as follows.
E LEMENT
Pressing the spacebar toggles this field for selection of
either the Near or Far unit as 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 E1 span.
T ARGET
This field selects the display of User or telco performance
registers. Telco registers are for viewing only and may not
be changed. The options are as follows.
[USER] [NET] - Display the user performance registers for
the network. This is only available if the E1-DTE option is
installed.
[USER] [DTE] - Display the user performance registers for
the E1 DTE.
[TELCO] [NET] - Display the telco performance registers
for the network.
[TELCO] [DTE] - Display the telco performance registers
for the E1 DTE. This is only available if the E1-DTE option
is installed.
E RROR E VENTS
This field displays the running total of error events for the
circuit selected in the Element field and is applicable only
when the Target field is set to User. This count accumulates
until it reaches 65535 or is reset by pressing ENTER with
the Reset field highlighted.
