The war of words between SAR telecommunications companies has intensified, with dominant operator Pacific Century CyberWorks accusing Wharf Group's i-Cable and New T&T of anti-competitive practices. CyberWorks deputy chairman Linus Cheung Wing-lam said the two Wharf companies had double standards over market deregulation, with one pushing for more and the other unwilling to open up. 'Our network is yours, and your network is also yours,' Mr Cheung said. 'That is an unfair practice except for a husband and wife.' Mr Cheung said CyberWorks would send a letter to the Office of the Telecommunications Authority (Ofta) today to push for a rapid opening up of i-Cable's hybrid fibre coaxial (HFC) network. A competitor to CyberWorks' interactive pay-television business, i-Cable has been actively leveraging its HFC network to grow its broadband Internet subscriber base in competition with CyberWorks unit Netvigator. Mr Cheung, however, declined to comment whether the company had any plans to lease i-Cable's network. He said the HFC network adopted a different technology from the mainstream networks, which made it hard to interconnect. Mr Cheung said i-Cable would not resume network connection after its subscribers discontinued its services, making it hard for subscribers to choose other operators. In response, an i-Cable spokesman said HFC was an open and technology-neutral network and that, for a charge, the company would reconnect subscribers if they made a request. 'We have been working with Ofta on these issues,' the spokesman said. 'They are picking an issue to confuse the public - it is like the pot calling the kettle black.' CyberWorks has been defending charges from i-Cable sister company New T&T and the other fixed-network operators such as New World Telephone that it is delaying the opening up of its network. Mr Cheung accused the other fixed-line operators, including New T&T, of committing 'major faults', including selectively providing services to commercial users, resisting investment in building networks, refusing to pay CyberWorks a HK$25 million fee for switching telephone numbers to new entrants and misleading the public. 'These accusations are absolute nonsense. They should have done more study before they made the accusations,' New T&T director Tony Cheung said. Last week, CyberWorks took out full-page advertisements in 10 Hong Kong newspapers, claiming 'We've done more to raise standards, the other players have let the side down'. Yesterday, Linus Cheung said more explicitly the other operators' unwillingness to invest was hindering deregulation. 'If our competitors are looking for investment, let them invest in their networks and do not depend on our network,' Mr Cheung said. 'After six years, they should have grown up, instead they are still wearing diapers.' Mr Cheung said New World Telephone, for example, had only 3,000 lines for its network, at an installation rate of less than a line per day. A New World Telephone spokesman declined to provide its number of self-built lines. In response to CyberWorks accusation that it is not committed to investing in infrastructure, New T&T hit back, saying the company had invested more than HK$500 million this year on capital expenditure. This included HK$120 million to lay down two domestic submarine cables. New T&T is also planning to invest in another three domestic submarine cables in the next three years, which could cost HK$300 million.
