REX 80-E is an extensible PABX which uses a reed-relay switching matrix with electronic common control.
Up to 140 junctions (each of which can be allocated to public-exchange or tie lines as desired) and 1000 extensions may be provided, although REX 80-E may be installed with as few as 25 junctions and 1 50 extensions and later extended, as the need arises, by the addition of equipment racks and switchboards via plug and socket connections. A useful range of features is included as standard, and many optional facilities are available to enable the system to be tailored to suit the requirements of individual customers.
The REX 80-E package incorporates an attractive desk-top switchboard with separate cabinets for the switching equipment. The cabinets contain their own mains-derived power supply units and are provided with locking lift off covers.
The simplicity of the system and the long life of the reed relays and solid-state components combine to make the PABX inherently reliable.
Easy maintenance is ensured by the provision of a fault printer and by the use of plug-in units and plug and socket rack interconnections.
*Additional racks may be provided at any stage of system growth to cater for special requirements.
