The introduction of digital PCM 30 channel multiplex equipment into the Australian network is being accelerated as part of the trend towards an integrated digital network. 2-wire loop interface equipment for the Australian network and in particular its special signalling requirements had not previously been available. This gave the Australian manufacturing industry the opportunity to design and manufacture a new line of equipment to Telecom's specification for what is now known as the PCM Loop Multiplex Equipment. Some of the design factors considered by Standard Telephones and Cables Pty. Ltd. are described (STC) and a summary of some of the innovative features as well as a general description of the resulting equipment are furnished.
