North American Philips Offers New Radio Telex System For Shipboard Communications

N.A. Philips Communications Systems has announced an advance micropressor-controlled error correcting system that links shipboard teleprinters to the worldwide Telex network. The new unit, called STB-750, installs between the vessel's high frequency radio and the teleprinter. Using ARQ, "FEC" and selective FEC error correcting techniques, it enables the vessel to exchange error-free traffic with any Telex terminal anywhere in the world.

The STB-750 is an advanced replacement for Philips STB-75 system, now installed on over 600 vessels and offshore platforms. The ships use H.F. radio to communicate with coastal stations, which are linked directly to the Telex landline network. At present, there are more than 30 coastal stations in Europe, North America, and Asia, providing total coverage to all shipping lanes. The advantage of radio telex, according to Philips Communications Systems, is its economy. STB-750 offers the same low error rates as satellite in most geographic areas, and error rates approaching the performance of satellite in fringe areas.

Major features of the new system include dialing from the teleprinter keyboard, automatic frequency drift correction, and buffer storage of up to 12,000 characters.
