Calix announced volume shipments of ADSL2+ interfaces for its Calix C7 platform. The company said its Calix C7 ultra-broadband loop carrier (UBLC) has the capacity to drive all ADSL2+ ports at peak line rates on a sustained basis. The Calix C7 offers 200 Gbps of capacity in a compact form factor, supporting 2,400 ADSL2+ ports in a single seven foot rack and as many as 1,920 ADSL2+ ports from its line of patented outdoor cabinets. Individual ADSL2+ ports can be clocked at downstream speeds as high as 24Mbps and will typically support services consuming 15Mbps of bandwidth at loop lengths of about 8Kft. The new ADSL2+ line cards are backward compatible with all existing ADSL CPE.
CenturyTel, the eighth largest ILEC in the United States based on access lines, is among the first Calix customers to deploy services based on ADSL2+.
Calix noted that ADSL2+, combined with codecs such as H.264 / MPEG-4, Part 10 and Microsoft’s Windows Media Player 9, provides the capacity to deliver HDTV programming along with multiple standard quality video streams, tiered Internet access, and packet voice over existing copper infrastructure. http://www.calix.com
