AT&T feature module 2 system manual Merlin II System Features

●If you aren’t using the full capacity of a line module, the control unit assigns the potential lines as well as the actual lines to buttons on your attendant consoles. It also assigns those lines to the main pool. A line jack with nothing plugged into it is called a nonequipped line appearance, or “ghost line. ” If you have any ghost lines, follow the procedures below to remove them from the main pool and to remove them from your standard attendant consoles.

●If you’re administering a new system, all your lines were initially assigned to the main pool (default pool 9). If you want to assign lines to other line pools, you must remove them from the main pool first.

●If a line appears as an individual line at a voice terminal in your system, it will disappear from that voice terminal if you add it to a line pool. Before adding lines to pools, make sure they aren’t needed as individual lines.
