Cisco Debuts D3 All-IP Line Card

Cisco's (www.cisco.com) uBR-MC3GX60V (3G60) Broadband Processing Engine is a high-density line card for the company's uBR10012 Universal Broadband Router and CMTS. It's intended for IP video services and to accelerate the transition to an all-IP network. Cisco is working with several major customers, including Comcast, Cox and others, to test the new line card.It provides 72 downstream and 60 upstream channels with full DOCSIS 3.0 capabilities per module. Upstream and downstream channels can be provisioned via software licensing, and customers can install the card and pay only for the channels they use. Channel capacity has increased tenfold, and the upstream channel capacity has increased threefold, per line card. Using the 3G60, a single uBR10012 can support up to 576 downstream and 480 upstream channels per chassis. The 3G60 supports DOCSIS 3.0 downstream channel bonding of up to 24 channels, allowing downstream speeds approaching 1.0 Gbps. The uBR10012 together with the 3G60 line card supports the full set of DOCSIS 3.0 features at scale, including IPv6, and supports dynamic bandwidth sharing.
