It's squinting-at-tables time as Alcatel-Lucent (NYSE: ALU), BT Group plc (NYSE: BT; London: BTA), Orange (NYSE: FTE) and Telefónica SA (NYSE: TEF) all reveal their latest results in today's regional roundup.

Alcatel-Lucent posted a 2.4 percent year-on-year increase in revenues in its second quarter, but this wasn't enough to allay wider worries about the market and prevent its share price tumbling. (See AlcaLu Grows But Pressures Weigh and AlcaLu Reports Q2.)

U.K. incumbent BT saw its revenues slide by 5 percent year-on-year to £4.7 billion (US$7.6 billion) in its fiscal first-quarter results, but, as Reuters reports, ruthless cost-cutting saw it still increase core profits by 3 percent, sending shares up 2.2 percent.

By contrast, rising costs at France Telecom saw the carrier record a 2.2 percent decline in first-half profits which, reports Bloomberg, took numbers to a level slightly below analysts' expectations. A 23 percent growth in mobile services in Africa and the Middle East helped steady the ship somewhat.

A strong performance in Latin America was not enough to stop second-quarter profits tumbling 27 percent year-on-year at Spanish giant Telefónica, reports Bloomberg. Certainly, the carrier's domestic market doesn't look likely to perk up anytime soon -- not for nothing is it going to cut more than 6,000 jobs in Spain.

Much-complained-about U.K. broadband provider TalkTalk managed to lose 27,000 broadband customers (net) in its first quarter, while revenues fell 5 percent year-on-year to £423 million ($690 million), reports the Financial Times (subscription required).

Irish incumbent eir , which has been under pressure from its creditors of late, has announced a €100 million ($143 million) investment in fiber infrastructure for the delivery of "super-fast" broadband and associated goodies (such as IPTV) to an estimated 100,000 premises by summer 2012. This represents the first phase of a program that will eventually see 1 million homes and business in the Republic connected to fiber, if all goes to plan.
