Loop-CO (L-CO) button
All CO lines can be assigned to a flexible CO button on a Proprietary Telephone. The assigned
button serves as an L-CO button. An incoming call on any CO line arrives at the L-CO button,
unless there are S-CO or G-CO buttons associated with the CO line or unless the button is
already in use. To make a CO call, you simply press the dedicated L-CO button. Pressing the
L-CO button provides the same operation as dialing the feature number for "Local CO Line
Access/ARS" (default = 9).
