More and more cable TV operators decide to deploy the DOCSIS 3.0 I-CMTS data transmission system. The advantages of this solution have been noticed and appreciated by another Polish company – Sileman from Ruda Śląska – which, in cooperation with VECTOR, has deployed the system in own projects.
The DOCSIS 3.0 I-CMTS data transmission system allows you to offer Internet access services with data rates higher than 100 Mb/s and to use the IP protocol for video transmission (IPTV services). The new DOCSIS 3.0 standard helps the operator to reduce operational expenditures: the power consumption is reduced while the density, scalability and efficiency of the solution are increased.
Sileman together with ELSAT and SFERA TV is a part of the Silesian Multimedia Group. Sileman is an Internet and telephony provider in four towns: Ruda Śląska, Bytom, Mikołów and Radzionków. The company offers the services based on the backbone fiber network which is 80 km long and on the dedicated microwave links. The subscribers may access the services via Ethernet or the ELSAT cable TV network.
A very important element of the DOCSIS 3.0 standard is a CMTS controlling the subscriber cable modem operation. Sileman has two CMTS devices installed by VECTOR. The devices are ARRIS C4 cable modem controllers for advanced IP services. ARRIS C4 allows the operator offering the advanced services of telephony, data and video transmission through the convergent IP network for individual and business customers.
The possibilities offered by the new system are recognized by more and more companies offering telephony, TV and Internet services. The new deployments of the solution entitle us to say that the DOCSIS 3.0 system is a success in the Polish market.

VECTOR has been designing and deploying DOCSIS systems for many years. We offer turn-key solutions including hardware, software and service support, starting with designing the solution, through the system implementation and integration with the operator’s network and systems, and ending with system maintenance and support during its operation.
The DOCSIS/EuroDOCSIS standard has evolved, offering in each new version the support of more and more advanced services:
- DOCSIS 1.0 – “best effort” Internet access services
- DOCSIS 1.1 – parameter guaranteed services, VoIP telephony
- DOCSIS 2.0 – symmetric transmission services (video conferences, P2P data exchange, private web pages)
The new standard version is DOCSIS 3.0, which offers very fast data transmission (up to 200 Mb/s) or Video over IP services with the Channel Bonding technology.
The deployment of a fast data transmission system can help a cable network operator to achieve many advantages:
- additional revenues thanks to the new interactive services offered to subscribers,
- service offer extension with new services responding to subscribers’ needs,
- TV network transformation into a broadband telecommunication network capable of sound, video and data transmission,
- the increase of the network operator competitiveness.
In order to deploy the DOCSIS 3.0 system, one needs not only proper headend equipment (ARRIS C4 CMTS), but also subsriber’s equipment (cable modems and multimedia terminals). VECTOR wants to offer all elements of the system, so it introduces new subscriber terminals compatible with the DOCSIS 3.0 system:

The sale of the ARRIS I-CMTS solution was conducted with the assistance of ARRIS Value-Added Resellers Net One Systems and KDDI.
Japan Cablenet selected the ARRIS Cable Modem Termination System solution in 2009 to deliver ultra-fast wideband data service to its customers. The ARRIS CMTS solution consists of the DOCSIS 3.0-qualified C4 CMTS and DOCSIS 3.0-certified WBM760C wideband modems, capable of delivering data speeds up to 160 Mbps, along with carrier-grade voice service. The technology is based on the DOCSIS 3.0 standard that supports both Upstream and Downstream channel bonding capabilities.
The ”Speed Star 160” rollout is especially significant in that it incorporates what is believed to be the industry’s first deployed service using Upstream Channel Bonding technology, which greatly enhances data rates. This technology not only greatly increases data throughput speeds to customers, but also ensures greater network reliability through noise reduction.
“We are very excited to be the first network in Japan, if not the world, to deploy Upstream Channel Bonding for our High Speed Data customers,” said JCN General Manager of business planning department and DOCSIS3.0 project manager, Hiroyoshi Takeyama. “This critical feature will make activities like the sharing of family pictures, home movies or other user-generated content a far more satisfying experience for our subscribers. It is our mission to provide our customers with the world’s fastest, most secure and most reliable super high-speed data service.”
