Configuring a Phantom Loop

A phantom loop is configured the same way as a normal loop with the exception of a ÒCÓ preceeding the loop number. It is important that a physical loop card be installed. A phantom DN can then be configured as part of a specific device group. After configuration changes to the loop card, the system must be reinitialized for the new settings to take effect. Phantom loops are only supported as local terminal loops. For more information, refer to X11 Software Features Guide (NTP 553-3001-305).

Note: The phantom terminal number of type ÒNÓ must not be used in place of ÒCÓ.
