Global sales of DSLAM equipment used to upgrade telephone exchanges to handle DSL broadband jumped 14 per cent in the third quarter to $872m.
Worldwide DSL customer premises equipment (CPE) revenue also rose, by 20 per cent to $550m, according to newly released research.
Analyst Infonetics reported that global DSLAM ports grew 15 per cent to 13.4 million from the last quarter to this quarter, and CPE units grew 26 per cent to 5.5 million.
DSLAM and CPE revenue growth is being fuelled by a rise in ADSL.
"DSLAM port shipments have been growing in the double-digit percentages for four straight quarters, jumping from 4.1 million in the third quarter of 2002 to 13.4 million this quarter, a sure sign that the DSL market has shifted into high gear," said Michael Howard, principal analyst at Infonetics and lead author of the DSL Aggregation Hardware report.
"On a similar track, by 2006, ATM DSLAM ports are projected to grow to 36 million, and IP DSLAM ports to 18 million."
The study found that Alcatel maintains the number-one position in every region for overall DSLAM port and revenue market share except Asia Pacific, where NEC leads in terms of revenue.
Geographically just over half of DSLAM revenue was from Asia Pacific, 31 per cent from EMEA and 13 per cent from North America.
Infonetics said that worldwide ADSL modem unit shipments were up 28 per cent from the previous quarter, with Siemens leading the sector in revenue market share with 23 per cent, followed by Thomson Multimedia with 15 per cent.
