Cable & Wireless Plc’s Mercury has teamed up with French company RCI-Calvacom to run its Mercury Link 7500, formerly the Cable and Wireless’s Easylink electronic mail service licenced from Western Union Corp, between France and the UK from next month. RCI-Calvacom is a year old company that aims to offer value added network services worldwide as France deregulates its market for value added network services. It is the first electronic mail link between France and the UK, according to managing director of Mercury Link 7500, David Flinter. The agreement between the two companies will also bring Mercury access to Germany, Belgium and French-speaking Africa as RCI-Calvacom’s network grows. Chairman of the French company Stephen Plummer says it also has a licencing deal with West German publisher of data processing technology Markt & Technik Verlag to extend its services in West Germany, Switzerland and Austria. RCI-Calvacom has around 4,200 subscribers, and is expected to increase that to between 10,000 and 18,000 by the end of 1987; Mercury’s customer base is some 160,000 strong including the US tie-up with Western Union.
