Other DEC announcements (the company had so many that it needed to bind them into a booklet) included an agreement with OTC Ltd, the Australian international carrier, for joint marketing of the latter’s public messaging and Electronic Data Interchange products – products that DEC seems to admit are better for telephone companies than its own EDI software: the company will also market Computer Generation Inc’s Cellular Real Time System, a rather neat-sounding package that interrogates a variety of cellular switches for information on customer usage; this data then either gets passed on to the billing system or can be used to establish more specialised billing services.
