Multi-Function Module Feature

Description

Although a device connected through an MFM may not have buttons, the system treats it as a multiline telephone with 34 buttons. In Hybrid/PBX mode, the system automatically assigns one SA Ring, one SA Voice, and one SA Originate Only button to the MFM. In Key mode, the system automatically assigns one ICOM Ring and one ICOM Voice button to the MFM. In Behind Switch mode, the system automatically assigns one ICOM Ring, one ICOM Voice, and one Prime Line button.

Do not attempt to enter extension programming from a device connected to an MFM. Program an MFM only through centralized telephone programming.

To ensure proper operation of a device connected through an MFM, the following should be performed through centralized telephone programming:

• Voice Announce should be disabled.
• SA or ICOM button assignments should be changed to one SA Ring or ICOM Ring, and either one SA Originate Only or one ICOM Originate Only button.
• Ringing/Idle Line Preference should be enabled.
• The Automatic Line Selection sequence should be set to the following:
• SA Ring or ICOM Ring
• SA Originate Only or ICOM Originate Only
• In Key and Behind Switch modes, outside lines that make calls from the MFM device
• In Behind Switch mode only, the Prime Line

When the Automatic Line Selection (ALS) sequence is set to select an SA or ICOM button, an outside line can be selected by dialing the Idle Line Access code (usually 9) in Key and Behind Switch modes or by dialing the pool dial-out or ARS code in Hybrid/PBX mode. If ALS is set to select an outside line button before an SA or ICOM button, the device cannot be used to make inside calls (inside calls can be received only).

• Ring Timing options should be set to No Ring for each outside line on which calls are not to be received.
• When the device is used only on Personal Lines for supplementary answering (such as an answering machine) or ringing (such as an external alert) and lines/trunks are assigned to or removed from the associated MLX telephone, the lines/trunks should also be assigned to or removed from the MFM.
• When the device is used for both inside and outside calls to supplement ringing (external alert) or to answer or screen calls (answering machine), calls can be redirected to the device by assigning a Primary Cover, Secondary Cover, Group Cover, or Shared SA button. In addition, an MLX telephone user can activate Forward and Follow Me to redirect incoming calls to the device. However, Coverage should not be used simultaneously with Forward and Follow Me.

Forward and Follow Me (including Remote Call Forwarding) and Privacy are not recommended, because there are no LEDs to indicate when the features are active.
