What does DOCSIS compliant mean?
DOCSIS protocols DOCSIS stands for “Data Over Cable Service Interface Specification.” It’s the protocol that lets an ISP provide internet service through a coaxial cable. It just means that your modem can provide broadband internet access. DOCSIS 3.0 and 3.1 are just version numbers.
What is the difference between a DOCSIS 3.0 and 3.1 modem?
The latest DOCSIS standard, DOCSIS 3.1 is capable of 10 gigabits per second (Gbps) download speeds and 1 Gbps upload speeds. However, the most widespread DOCSIS standard is DOCSIS 3.0, which is capable of 32 download channels at one time and over 1GB download speeds.
What do the numbers on cable modems mean?
Cable modem channels are displayed as “downstream channels number x upstream channels number.” For example, 8×4, 24×8 or 32×8. For example, 8×4 means that your cable modem has four (4) download channels and eight (8) upload channels. The higher the numbers, the faster the speeds.
What speed does Docsis 2.0 support?
The Evolution of DOCSIS
| DOCSIS 1.0 | DOCSIS 2.0 | |
|---|---|---|
| Highlights | Initial cable broadband technology, high speed internet access | Higher upstream speed, capacity for symmetric services |
| Downstream Capacity | 40 Mbps | 40 Mbps |
| Upstream Capacity | 10 Mbps | 30 Mbps |
| First Specification Issue Date | 1996 | 2001 |
Will Docsis 3.1 increase upload speed?
The DOCSIS 3.1 specification released in 2013 theoretically allowed 10Gbps downloads and 1Gbps upload speeds, but actual implementations never came close to those numbers. “DOCSIS 4.0 cable modems will support capacities up to 10Gbps downstream and 6Gbps upstream.”
Where is a DOCSIS 3.0 modem termination system located?
A DOCSIS 3.0 cable modem A cable modem termination system A DOCSIS architecture includes two primary components: a cable modem located at the customer premises, and a cable modem termination system (CMTS) located at the CATV headend. Cable systems supporting on-demand programming use a hybrid fiber-coaxial system.
Who is the first cable provider to use DOCSIS 3.1?
In the United States, broadband provider Comcast announced in February 2016 that several cities within its footprint will have DOCSIS 3.1 availability before the end of the year. At the end of 2016, Mediacom announced it would become the first major U.S. cable company to fully transition to the DOCSIS 3.1 platform.
When did DOCSIS 1.0 become an international standard?
The ITU Telecommunication Standardization Sector (ITU-T) has approved the various versions of DOCSIS as international standards. DOCSIS 1.0 was ratified as ITU-T Recommendation J.112 Annex B (1998), but it was superseded by DOCSIS 1.1 which was ratified as ITU-T Recommendation J.112 Annex B (2001).
What’s the difference between DOCSIS and EuroDOCSIS certification?
The wider channel bandwidth in EuroDOCSIS architectures permits more bandwidth to be allocated to the downstream data path (toward the user). EuroDOCSIS certification testing is executed by Belgian company Excentis (formerly known as tComLabs), while DOCSIS certification testing is executed by CableLabs.
