Footnotes:

10Gbps is the maximum data transfer rate in the DOCSIS® 3.1 standard. In practice, your Internet speeds will be less, as the transfer rate through the CM3000 Gigabit Ethernet port is limited to 2.5Gbps. The internet speeds may also be reduced by the volume of network traffic or your service plan. Maximum rate is derived from DOCSIS® 3.1 specifications and actual throughput will vary depending on your internet subscription with your provider. Gigabit service plans & compatible cable modem required for Gigabit or Multi-Gig Internet speeds.

‡‡CM3000 is prepared for today and tomorrow with both mid/split and high/split technology. Mid-split technology is currently being offered by some ISPs in some regions. High/split technology may be offered by ISPs in the near future. Please check with your ISP regarding mid-split and high/split compatibility.

1Compared to DOCSIS® 3.0 and Low-Split. Maximum rate is derived from DOCSIS® 3.1 and Mid/High-Split specifications and actual throughput will vary depending on your Internet subscription with your provider.

2 Savings shown may vary by cable service providers.

* The internet speeds and actual throughput will vary depending on your internet subscription with your provider or volume of network traffic.
