The ZyXEL Device supports transmission speeds of up to 43
Mbps upstream and 30 Mbps downstream. Actual speeds
attained depend on your cable operator’s CMTS (Cable Modem
Termination System).
Note: The standard your cable operator supports
determines the maximum upstream and downstream
speeds attainable. Actual speeds attained depend on
the distance from the cable operator’s central office,
noise, and so on.
