Card Configuration System Configuration and Operation
4.4.5 Test and Debug Screen
You can also go from the System Main Screen to a Test and Debug Screen, which allows you
to perform system-level maintenance operations. You can back up the system configuration
onto an external computer after saving and subsequently editing it, and (if necessary) you can
restore that configuration to the system. You also can erase the system configuration and
restart the system with a single “zip” command. Or, you can re-register your system
configuration if you change to a different chassis.
The system software also has a built-in debugging utility. However, this utility is only
available to factory software engineers. The system maintenance functions are described in
the “Testing and Debugging” section later in this chapter.
4.4.6 Time Slot Configuration and Cross-Connect Screens
From the System Main Screen, you also can access a Configuration Screen that lets you
automatically configure the system. This time-saving function assigns DS0 time slots of the
system’s T1 and E1 WAN lines to certain user voice and data cards in your system. Or, you
can access a lower-level screen that lets you cross-connect DS0 time slots between two T1 or
E1 lines connected to the system. Refer to these time slot configuration operations later in this
manual.
4.5 Card Configuration
4.5.1 Selecting and Configuring Your Cards
The System Main Screen lists all installed cards next to their slot numbers. To access a card
from the Main Screen. Move the cursor in the Installed column with the arrow keys until the
desired card is highlighted, then press <Enter>. The associated Card Main Screen now
appears.
Use the arrow keys to move the cursor around in any card screen. When changing card
parameters, some settings require you to enter your own values on the keyboard, while others
allow you to select from a list of pre-programmed option settings.
To enter a user-defined value in a field, first highlight that field by moving the cursor to it and
press <Enter>. Then, type the desired value on your keyboard and press <Enter> to store it in
that field.
To choose an option setting from a list of displayed options, press <Enter> with the associated
parameter field highlighted. A series of available option settings now appears for that field.
Use the right-arrow and left-arrow keys to move the cursor to the desired setting, and press
<Enter> to store that setting in the highlighted field.
