Additional keys and functions for your business phone

Increase your speed, functionality and range with the Maxwell Expansion Module, designed for the Maxwell Basic, Maxwell 2, Maxwell 3 and Maxwell 4 desktop phones (not for Maxwell C).

The Maxwell Expansion Module features a large 7" FSTN display with extended function keys on two sides, each with 29 flexible keys. This allows up to 58 functions, such as busy lamp fields (BLF) and speed dialling.  The keys can also be easily programmed to log on and off, activate the answering machine or even open the front door.

Self-inscribing keys

The Expansion Module is equipped with a large 7" display that shows the functions of the keys. The function is located right next to the button and all function changes are automatically shown as text. Manual labelling is no longer necessary.

Programmable keys

The module has 58 keys distributed on two sides. One button is used to switch between pages and the other buttons can be used for functions such as BLF and speed dial. They can also be conveniently programmed as access codes, to activate the answering machine or to log on to your machine.

Phone extension

Maxwell Basic, 2 and 3 support up to three expansion modules and offer users more keys for additional function settings; a total of up to 174 function keys with 3 modules are possible. The first keypad module draws power from a power supply, while the second and third modules are connected to and powered from the first keypad module.

Keys with three colours

Each key has a three-color LED that represents the respective status. A green light indicates that the line is clear, a red flashing light indicates that a call is coming in, a persistent red light indicates that the line is busy, and a yellow light indicates offline.

Matching the Maxwell Design

The design of the Maxwell Expansion Module is matched to the appearance of the Maxwell series. Everyone uses their phone differently, so the Maxwell series has a movable base that allows three different tilt angles from 120-140 degrees. The Maxwell phones and Expansion Modules can also be wall-mounted.
