Time Slot Configuration Screen System Configuration and Operation
5.8 Time Slot Configuration Screen
From the System Main Screen, you can access a Configuration Screen by pressing “c”
(Config) 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.
5.9 Deleting an Out of Service Card
When a user card is out of service the screen will display an OOS in the status field next to the
associated card installed. If you still want to remove this card press “d” (Del) to delete this
card from the System Main Screen. The system will display a message, “OK to lose card
settings (y/n)?”, press “y” and the system will remove that card from the System Main Screen.
5.10 Accepting New Card Settings
When a user card is replaced with a different type of card the system will remove the current
card settings. The system will show “REJ” on the System Main Screen. Press “t” (accepT) in
the System Main Screen to accept the new settings.
5.11 Cross-Connecting (XCON)
From the System Main Screen, you can access a Cross-Connect Screen by pressing “x”
(Xcon) that lets you cross-connect WAN time slots between T1 and E1 links. Refer to the
Cross-Connecting WAN Time Slots Section 5.20 on page 54 of this chapter.
5.12 System Level Maintenance
You can also go from the System Main Screen to a Test and Debug Screen, by pressing “y”
(sYs) 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 (refer to the backup and restore
section later in this chapter). 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.
