* Actual speeds will vary, and are often less than the maximum possible. Data transmission speed is approximate and depends on the configuration and capacity of your network, as well as the
amount of traffic on the network.
** Actual data throughput will be less due to physical layer overhead (error correction coding, burst preamble, and guard interval).
*** With A-TDMA or S-CDMA enabled CMTS.
**** With S-CDMA enabled CMTS.
