Initiating an ATI Session
Once the appropriate configuration option changes have been made and access is
established, the Main Menu screen appears (unless a password is required).
Figure I-1, Main Menu Screen, shows the Main Menu screen for a standalone
DSU/CSU.
The carrier-mounted DSU/CSU shows the 3000 Series carrier slot num ber under
the Customer ID. The slot number field (e.g., Slot: 1) is changed to access specific
DSU/CSUs in the carrier. For Telnet or SNMP access to the carrier, specify the IP
address of the applicable communication port (see Appendix G,

IP Network

Addressing Scenarios

).
NOTE:
By convention throughout this appendix, examples of screens are shown as
they appear with the standalone DSU/CSU.
If a password is required, the Login screen displays the prompt for password input.
(Refer to

Entering a Password to Gain Access

on page I-14.)
To move between the Screen area and the Screen Function Keys area (Figure I-1,
Main Menu Screen), press Ctrl-a (Control key and a).
From the Screen area, you may select the Status, Test, Configuration, or
Control branches.
