The ARRIS Motorola SB6121 SURFboard DOCSIS 3.0 Cable Modem unlocks the potential of offering innovative high-bandwidth data and multimedia services. This item enables channel bonding of up to four downstream channels and four upstream channels, which allows an operator to offer their customers advanced multimedia services with data rates of well over 100Mbps in each direction. The Motorola modem provides an economic option for providing ultra-broadband services, with four times the current maximum user data throughput. It approximates 160Mbps in DOCSIS mode and 195Mbps in EuroDOCSIS mode, without the need for hybrid fiber coax (HFC) plant upgrade. Maximizing an operator's current infrastructure investment, the SURFboard modem can be deployed without service interruption. It supports both IPv4 and IPv6 for added versatility. An internal low-pass fitler eliminates MoCA signal overload.  ARRIS/Motorola SB6121 SURFboard DOCSIS 3.0 Cable Modem: Channel bonding of up to 4 downstream channels and 4 upstream channels increasing data rates of well over 100Mbps in each direction SURFboard modem supports IPv4 and IPv6 Supports AES traffic encryption Motorola modem features enhanced network management Ability to provision and manage IP multicast GigE (RJ-45) data port with auto negotiate and Auto MDIX User-friendly online diagnostics Power saving energy conservation switch Internal low pass filter to eliminate MoCA signal overload SURFboard modem can be installed and activated without disrupting service
