Semi-automatic Small Private Branch ExchangeMXE 72 is the PBX for small organisations where personal service and low cost are of first importance. It sets a new standard in small-PBX design by combining the simplicity of person-to-person connection via fast operation keys on an operator's switchboard with the benefits of many features only found on fully automatic systems.
Up to 10 public exchange lines and 72 extensions can be provided, but the modular equipment practice ensures that this PBX can be tailored to suit any individual requirements.
The MXE 72 package incorporates an attractive desk top switchboard with a separate cabinet for the switching equipment. The power supply and main terminating frame are built into the cabinet.
The switchboard features direct extension selection and pushbutton working with all types of public exchange. A logical operating sequence allows calls to be processed quickly and efficiently, and its simplicity enables the untrained user to become proficient with minimum instruction.
Installation is simple. To ease handling the MXE 72 is delivered as a set of units which are rapidly assembled on site, so there are no problems in installing the equipment in difficult locations. The switching cabinet itself is compact, virtually silent in operation, and entirely suitable for the office environment although it may be installed remote from the switchboard in any out-of-the-way place if preferred.
Expert staff are not needed to maintain the MXE 72. The crossbar switching matrix, long-life relays and solid-state components are inherently reliable, but if a malfunction does occur, swing-out gates make inspection and servicing easy. When alterations or additions are required to the line plant, a door on the right of the cabinet allows unrestricted access to the main terminating frame area.
