FAQ:

Q: What is the Motorola sb6121 surfboard cable modem?

A: Motorola’s easy-to-use SB6121 SURFboard DOCSIS3.0 Cable Modem unlocks the potential of offering innovative high-bandwidth data and multimedia services to customers. The Motorola SB6121 SURFboard DOCSIS 3.0 Cable Modem provides operators with an economic option for providing Ultra-Broadband services.

Q: Why choose sb6121 for ultra broadband?

A: for providing Ultra-Broadband services, with four times the current maximum user data throughput approximating 160 Mbps in DOCSIS mode and 195 Mbps in EuroDOCSIS mode*, without the need for hybrid fiber coax (HFC) plant upgrade. Maximizing an operator’s current infrastructure investment, the SB6121 can be deployed without service interruption.

Q: Does the sb6121 support IPv4 and IPv6?

A: Backwards compatible to DOCSIS 1.0, 1.1 and 2.0, the SB6121 also supports both IPv4 and IPv6, Advanced Encryption Services, and all other DOCSIS 3.0 standards.

Q: What is the difference between the sb6121 and the D-Link?

A: The Motorola SB6121’s colored graphical-icon LED indicators are much easier to identify and read from a distance than the D-Link’s closely spaced row of identical yellow-green LEDs. You can look at it from across the room and see two steady blues and one blinking amber, and know at a glance you’re in good shape.
