What is DOCSIS

teleste dah

Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access over their existing hybrid fiber-coaxial (HFC) infrastructure.

EoC products

Ethernet over Coax (EoC) technology offers an attractive option for building professional, standard-based and next generation IP networks. It enables operators to bring gigabit broadband connections to consumers by utilizing the existing coaxial cabling that also carries the free-to-air and CATV signals around the building.


The DOCSIS Access Hub (DAH) will extend your IP network over the existing coaxial cabling used in the infrastructure of the establishment. It enables high-speed broadband connections to your customers with considerably low costs and without installing new cabling.




Already in almost every building that has TV screens installed. It is also very easy to add on extensions to the existing network.



Can carry all forms of Live TV, Radio, CCTV as well as having space for high Speed Internet data.


Cost of installation and setup

Very low cost, as the cabling is already in the building, so often only some simple maintainance and updating is required to make an efficient TV and data network.


Best used for

Upgrading existing properties as a coax network is already installed to each TV point.


Ethernet (Cat 5/Cat 6)



Data cabling can be found in most buildings, but this rarely reaches every bedroom.



Can only be used to carry data, with a 100m limitation on distance.


Cost of installation and setup

It is costly and disruptive to install a new Cat5 network, as it is invasive to the fabric of the building.


Best used for

New build properties where it is easy to run a Cat5 cable network to every TV point during the build.
