COLORADO SPRINGS, Colo. " Ovum, the market research arm of Datamonitor Group, has reported a continued decline in DSL port shipments in the first quarter of calendar 2008, compared to continued growth of Cable Modem Termination System ports. CMTS deployment, still only a fraction of DSL shipments, is continuing to show a growth trend in all regions. The only market in which DSL continued to grow was Asia, reflecting the continued Digital Subscriber Line interest in initial strong markets such as Korea.
DSL global port shipments were 20.3 million in the first quarter, though the shipment of DSLAMs overall were 16 percent down from the previous quarter, and 10 percent down from first quarter of 2007. CMTS shipments, a 198,000 worldwide, were up 28 percent from the previous quarter, and up 54 percent from one year ago.
Ovum shows Cisco Systems having a commanding lead in CMTS, due in part to its acquisition of Scientific-Atlanta, with a 55 percent market share, followed by Arris with 32 percent and Motorola with 10 percent. The DSLAM market is more fragmented, with Alcatel-Lucent leading with a 35 percent market share, followed by Huawei with 23 percent, ZTE with 13 percent, Nokia-Siemens Networks with 6 percent, and Ericsson with 6 percent.
