Worldwide DSLAM shipments grew in the first quarter, but CMTS shipments declined, according to Ovum-RHK.
DSLAM shipments were up 2 percent sequentially, and up 12 percent from the first quarter of 2006, while CMTS shipments were down 13 percent sequentially, and 10 percent compared to last year.
Alcatel-Lucent, which shipped 7.3 million DSL ports, remains the dominant vendor on a rolling 4-quarter basis, with 35 percent market share, followed by Huawei, ZTE, Ericsson, Siemens and Fujitsu, Ovum-RHK reported.
In the CMTS market, Cisco remained the dominant vendor with 51 percent rolling 4Q market share followed by Arris (29 percent), Motorola (17 percent) and BigBand (3 percent). Arris increased market share by 3 points, and Motorola edged up by 1 point.
Separately, Ovum reported that global service provider switching and routing equipment Q1 sales were $2.4 billion, up 12 percent from last year.
"Alcatel-Lucent continued its strong IP/MPLS growth, and Juniper Networks returned to growth after being mostly flat in 2006,” said Mark Seery, vice president, switching and routing, at Ovum-RHK. “Both IP and Ethernet over MPLS continue to grow, strongly driven by NGN transformation and the impact of video.”
