Plessey Co Plc has made headway with its payphones in two Far East markets, Australia and Singapore, traditionally dominated by Japanese suppliers: it has a UKP2m-a-year pact from Telecom Australia for an estimated 2,000 payphones, starting in May; and UKP3.5m for 4,000 pre-pay card and credit card payphones and 500,000 payphone cards, as well as a cashless calling system at Changi international airport; the phones will be made by Plessey Australia.
