4.4.4 Card Main Screens
Each card in the system has a Card Main Screen associated with it. You can go from the
System Main Screen to any Card Main Screen and configure that card. From a Card Main
Screen, you can access a Test Screen to perform tests on the card, or (in some cases) a
Performance Monitor Screen to view transmission performance data.
Figure 4-10 shows a typical Card Main Screen. The highlighted line at the top of every screen
is the header. It lists the node name of the system, the current card type and abbreviated
description, the card design revision and serial number, and the current system date and time.
The card configuration parameters and current option settings appear in numerous rows and
columns below the header. This region of each screen lists the options the left and one or more
associated columns of data fields from left to right. You can change the settings in those fields
as required for each card.
The status and data entry change line appears just above the bottom line of the screen. When
you choose a field to edit and press <Enter>, this line shows the currently available option
settings for that field. Make all configuration changes on this line.
The highlighted area in the upper right corner shows the current alarm status data. In Figure
4-10, an Out-Of-Service (OOS) alarm has occurred on the card in chassis slot U3.
