High speed digital subscriber line maker PairGain Technologies Inc said its figures have failed to meet the expectations of analysts despite reporting very respectable interim results. Turnover for the six months to June 30 rose 56.3% to $137.1m while net profit was up 70.5% at $23.1m. The Tustin, California company that paid $94 in shares for the acquisition of Avidia Systems Inc earlier in the year (CI No 3,105), says it and similar companies have had a rough ride of late with pricing pressures and rumors of deals unsettling the market. The company managed to boost its international sales by 223% with the introduction of a new product line in the second quarter.
