Cable Modem enables service providers to offer unprecedented speeds on an HFC network. The cost-effective CMD31T/CME31T bonds four channels in each direction together to deliver usable downstream data rates of 152 Mbps (CMD31T, DOCSIS) or 200 Mbps (CME31T, EuroDOCSIS) with 108 Mbps upstream (up to four times that of conventional DOCSIS 2.0 technology). The CME31T also provides hybrid mode. This feature allows the service provider to deploy the CMD31T/CME31T in a network that uses EuroDOCSIS 8 MHz downstream channel. The CMD31T/CME31T is fully compliant with DOCSIS 3.0 and is backwards compatible with DOCSIS 2.0, 1.1 and 1.0. The CMD31T/ CME31T have been Cable Labs certified against industry leading channel bonding cable modem termination systems. The CMD31T/CME31T is future proof with support for IPv6.
