What is the significance of DOCSIS and

EuroDOCSIS?

DOCSIS and EuroDOCSIS are international standards

that many cable products comply with. The standards

ensure that interoperable, multiple-sourced headend and

cable modem products are delivered to market that work

together. DOCSIS and EuroDOCSIS is based on IP

packets—the native format of the Internet. DOCSIS and

EuroDOCSIS support mechanisms that promote

multi-tiered Internet access and interactive cable modem

and set top box data and control. The standard provides

QoS capabilities to differentiate data and VoIP service

offerings.

DOCSIS and EuroDOCSIS standards evolve through a

proposal and approval process between the DOCSIS or

EuroDOCSIS community. The community includes cable

operators, vendors, and Internet service providers (ISPs).

Many cable operators, networking companies, cable

equipment manufacturers, consumer electronics and

modem companies support the DOCSIS and

EuroDOCSIS standards. Adherence to these standards

ensure that products scale and interoperate to enable

advanced services such as high-speed data via a cable

modem, digital TV, video on demand, and cable

telephony. This gives you freedom of choice. The move to

a standards-based approach lowers costs, increases

reliability, and facilitates the rapid deployment of new

services.

Disparate solutions that are not standards-based

inherently lack scalability. A network of many elements,

separately managed that does not interoperate, creates a

complex network and skyrockets operational costs.
