*When compared to traditional 28.8k analog modems. Actual speeds will
vary, and are often less than the maximum possible. Upload and down
load 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).
**Actual speeds will vary. Speeds of 30 Mbps per second are only
attainable with A-TDMA technology.
* **With A-TDMA enabled CMTS.
