Shares of Catapult Communications ( CATT) were among technology's losers Wednesday, sliding 9% after the maker of digital telecom test systems cut its third-quarter revenue outlook.

The company now sees revenue of $10.7 million to $11.7 million for the quarter ending June 30, down from an earlier view of $12.8 million. Analysts polled by Thomson First Call project revenue of $12.8 million. "Order input for the quarter is falling short of our expectations, which indicates that revenues will not recover from second quarter levels to the extent we originally anticipated," Catapult said in a press release. Shares recently were trading down $1.15 to $12.

Andrew ( ANDW) rose 5% after the telecom supplier agreed to be acquired by ADC Telecommunications ( ADCT) for about $2 billion in stock.

That price represents 30% premium over Andrew's closing price Tuesday of $9.78. The deal is expected to close within four to six months. Shares of Andrew were trading up 52 cents to $10.30, while shares of ADC tumbled $4.22, or 19%, to $18.16.
