This procedure provides instructions for viewing or editing the loopback

configuration for HLXC modules.

 A “toggle” field type means the user can press the space bar to view and select the

next option that is described; or the user can press the “R” key to view and select the
previous option. An “input” field type means the user must type an entry in the field
according to the parameters described. A “fixed” field is locked, and cannot be changed by
the user.

 Edits can be made in the configuration database in one of two ways: 1) If the

complete field is highlighted, use the space bar to toggle forward or the “R” key to
reverse toggle through the options for that field. 2) If only the first space or the field is
highlighted, type in the data that applies to that field.

Edits to the configuration database can be saved after each change in one of two

ways: 1) Press an arrow key and then Enter or Return once; or 2) Press Enter or Return
twice

 after all selections and entries are made in the screen but before leaving the screen.

If the entries have been accepted, a message “Configuration Successful… Press Any Key
To Continue” appears on the screen.

 Press CONTROL-A for help information on moving around and editing fields.
