Updated from 12:25 p.m. EDTDeutsche Telekom said that sales and earnings at its combined Internet and fixed-line operation would fall further this year, sending the stock lower by nearly 8%. Europe's largest telecom group said it expects revenue for its German fixed-line unit to fall between 4% and 6% in 2008 as it struggles to compete with cable all-in-one packages. Adjusted earnings before interest, taxes, depreciation and amortization at the German unit should decline by 5% to 8% this year, according to the company. Timotheus Hoettges, head of Deutsche Telekom's fixed-line operation, said during a conference call that revenue should stabilize by 2010. "Our fixed-line strategy is taking off and we will manage to stop revenue decline," he added. "We will succeed in slowing the sales decline compared to last year.''
