Features
Considerations and Constraints
When both the MLX telephone and the device connected to an MFM are in use,
the Voice Announce to Busy feature cannot be used to reach the MLX
telephone user.
The tip/ring or SAA interface is selected by setting pin straps in the MFM. Only
authorized technicians or dealer representatives can install or set options in the
MFM.
When Ringing/Idle Line Preference is turned on for an MFM and Automatic Line
Selection is set to an outside trunk, inside calls cannot be made and features
cannot be used. Both inside and outside calls can be received.
Calls are independently sent to the MLX telephone and its associated MFM.
The following features can be used when the user wants calls to be received at
both the MLX telephone and the device connected to an MFM:
■ Cover buttons
■ Shared SA buttons
■ buttons assigned the same outside lines
■ Forward and Follow Me
■ Transfer
An MFM can be assigned as a calling group delay announcement or as a
Calls-in-Queue alert for a calling group queue.
Tip/ring devices connected on an MFM should not be used with Call
Management System (CMS).
Tip/ring applications that require a switchhook flash for operation (such as
MERLIN Attendant or MERLIN MAIL Voice Messaging System) cannot be
connected via an MFM because the system ignores the switchhook flash sent
by the device.
When a Shared SA button or a shared Personal Line is assigned to the MFM,
the device cannot detect when a line is picked up by the sharing user.
Therefore, if an answering machine with the built-in ability to disconnect when
another person picks up the same line is connected to the MFM, the machine
does not automatically disconnect if the user picks up a call on the shared line
that was already answered by the answering machine.
If the MFM is assigned as a Primary Individual Coverage receiver and the MLX
telephone user uses Forward or Follow Me, and if an answering machine that
disconnects when another person picks up the same line is connected to the
MFM, the machine does not automatically disconnect if the forwarding
destination picks up the call.
