Cisco’s Modular DOCSIS 3.0 Downstream Channel Bonding Solution
The Cisco Modular DOCSIS 3.0 Downstream Channel Bonding solution delivers greater bandwidth at lower cost. Two key characteristics allow this to be possible. First is channel bonding, which combines several radio frequency (RF) channels into one “virtual” channel. Data rates in this virtual channel range from the hundreds of megabits to potentially gigabits per second. This creates more available bandwidth in the network and helps cable operators offer new, more bandwidth-intensive services. The second characteristic is modularity made possible with the use of edge quadrature amplitude modulation (QAM) technology. Cisco's Modular DOCSIS 3.0 Downstream Channel Bonding solution uses existing, relatively low cost, edge QAMs – the same technology used for current videoon- demand (VOD) applications.
