Racal Electronics Plc’s Racal-Milgo GmbH has won the contract from the Deutsche Bundespost to implement the Temex network, which will enable the transmission of data-over-voice on the public switched telephone network. The system is designed for applications such as remote reading of utility meters, data collection for things like burglar and fire alarm and alarm messages from the housebound, and similar low-traffic uses. Data takes up a small part of the bandwidth and does not affect conversations on the same line. Subscribers will rent a low-cost interface from the Bundespost; the network is claimed to be the first of its kind in the world. Racal-Milgo says the initial contract, worth UKP10m, is likely to reach UKP40m over the five-year implementation period.
