COMPANIES using the Internet via dial-up connections will gradually migrate to leased lines, according to Internet Service Provider (ISP) Hong Kong Internet & Gateway Services (HKIGS.) HKIGS marketing manager, Roger Lau said security concerns had kept many companies currently using the Internet from taking a leased line. HKIGS currently has about 20 corporate customers with leased lines and about 1,000 dial-up users, excluding corporate dial-up customers. It has 'about 20' corporate leased line customers including major accounts China Light & Power, Nomura, System Pro and Datacraft. Leased lines are available at 9.6, 19.2 and 64 kilobit per second (Kbps.) Mr Lau said HKIGS's revenue was split about 50:50 between leased line and dial-up customers but this was likely to change as the on-line market matured. 'There are not that many companies using the Internet through leased lines in Hong Kong,' he said. 'Many are using dial-up, but as they build up knowledge of the Internet, they will migrate. We expect this in about one or two years.' Some companies hesitate to enter the Internet via leased lines out of fear that the link between their local networks and the Internet could provide a route for hackers. But security measures now available make leased lines more secure than dial-ups, according to HKIGS operation manager Aaron Tung. Mr Tung said corporate activity on the Internet was on the increase, with enquiries growing daily. HKIGS uses one 64 Kbps line to link into its US service provider, Advanced Network Services, but plans to soon upgrading to 256 Kbps.
