*When comparing download speeds with a traditional 28.8k analog modem. Actual speeds will vary, and are often less than the maximum possible. Upload and download speeds are affected by several factors including, but not limited to: network traffic and services offered by your cable operator or broadband service provider, computer equipment, type of server, number of connections to server, and availability of Internet router(s).

1. Check with your local cable operator to determine the number of connections allowed and associated service charges.

**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.
