BigBand adds channel bonding

BigBand Networks has added channel bonding capabilities to its modular-cable modem termination system (M-CMTS), a key ingredient of DOCSIS 3.0, a CableLabs specification that promises to enable data speeds in excess of 100 Mbps.

Channel bonding is a method in which multiple slices of 6 MHz spectrum (or 8 MHz for some operators outside North America) are combined to create one logical - and higher capacity - pipe. A key goal of the M-CMTS is to enable the cable network to share edge QAM resources for video-on-demand and DOCSIS-based services and applications.

At next week's National Show in Atlanta, BigBand will demonstrate the capability on its Cuda CMTS and BigBand BME (Broadband Multimedia-service Edge) platforms, which will be hooked into a wideband cable modem based on Broadcom Corp. silicon.
