LOOPBACK STATUS/COMMANDS

Summary: This procedure provides instructions for displaying the currently active loopbacks for all circuits in the system, and for enabling/disabling loopbacks.

Caution: Do not perform a DS3 loopback when the Soneplex Broadband chassis is connected to a DS3 CAM unit in the Soneplex CCAS system.

Note: 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 of the field is highlighted, type in the data that applies to that field.

Note: 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.
