Telephones in Key and Behind Switch Mode

The line buttons you assign to the telephones or the adjuncts connected through
an MLX telephone using an MFM are the following:
Intercom Ring (ICOM Ring) button
Intercom Voice (ICOM Voice) button
Intercom Originate Only (ICOM Orig Only) button
Loudspeaker Paging button
Personal line button (Key mode only)

Factory Assignments
The system automatically assigns certain kinds of line buttons depending on the
type of equipment and the mode of operation:
In Key mode, the system assigns an ICOM Ring button and an ICOM
Voice button; the first eight outside lines connected to the control unit are
assigned to each nonoperator multiline telephone beginning with Button 3.
In the Behind Switch mode, the system assigns an ICOM Voice button, an
ICOM Ring button, and one prime line button (Button 3) to every
nonoperator multiline telephone.
For either mode, the line/trunk assignment is the same for both analog
multiline and MLX telephones.

telephones.
NOTE:
In the Behind Switch operating mode, the system automatically
assigns two prime lines to each port on an MLX module—one for the
MLX telephone and one for the device connected to the
Multi-Function Module (MFM). If an MFM is not connected to an MLX
telephone or the MLX port is not used, the prime line for the MFM
can be removed. The prime line can then be assigned to other users.
