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.

It also makes possible to use the IP protocol for video transmission (IPTV services). The new system reduces the operational costs of cable TV operators by the power reduction and increases efficiency and reliability of the solution. It reduces the cost per each Mb of the network traffic.
Astra-Net has appreciated the advantages of DOCSIS 3.0. The company has been present in the Wielkopolska district since 1989. The company offers services in the area of cable TV, broadband Internet access, digital TV and telephony. The offered products have the highest quality and are based on the latest technological solutions responding for increasing customer needs.
“The deployment of the DOCSIS 3.0 system will allow us to offer fast data transmission services up to 200 Mbit/s and to broaden our offer with new services responding for needs of more and more demanding customers. Our competitiveness will be higher thanks to the deployed system. The reduction of the transmission cost is also very important for us, as well as the flexibility of downstream and upstream configuration”, said Mr. Zbigniew Ryczek, the President of the Astra-Net board of directors.
The DOCSIS 3.0 I-CMTS fast data transmission system arouses interest of cable operators offering TV, data and telephone services. VECTOR will be informing about the system introduction by the next cable operators.

Anadigics Inc. has released an RF front-end chipset consisting of the ARA2017 programmable gain upstream amplifier and the AIT1061 integrated wideband data tuner. Suitable for cable modems designed to meet the new DOCSIS 3.0 standard, Anadigics claims ARA2017, the first upstream amp available for Docsis 3.0, while AIT1061, the smallest form factor (6-by-6-by-1mm) of any current Docsis 3.0 tuner.
ARA2017 delivers output power levels of 64dBmV with very low (-55dBc) harmonic distortion and output noise levels as low as -53.8dBmV. The ARA2017 form factor is a 28-pin QFN 5-by-5-by-1mm package.
The wide capture bandwidth of the AIT1061 tuner enables the simultaneous reception of multiple channels and the linearity of both components in the chipset preserves the integrity of each channel. The ARA2017 upstream amplifier’s high output power capability and low voltage transients also meet the new standard’s specs for power output.
The AIT1061 includes all the functions of a double-conversion wideband data tuner and integrates up-converter, down-converter, VCO, synthesiser, IF amplifier, RF gain control and IF gain control. AIT1061 maintains exceptional linearity over wide RF input and IF capture bandwidths to accommodate multi-channel operation.
Docsis 3.0 enables downstream data rates of 160Mbps and upstream rates of 120Mbps, which represent 4x the speed of today’s cable modem networks. Fast enough for IPTV service, these speeds are achieved by “bonding” together multiple data channels for higher throughput.
It also features high gain and low noise figure. The AIT1061 operates from a single 5V source, eliminating the need for a second power supply.

Data over Cable Service Interface Specifications is an extensive set of specifications developed by CableLabs, its cable operating company members and key suppliers in the broadband industry. The DOCSIS 3.0 specification establishes ways for cable companies to tie multiple 6 MHz transmission channels together to deliver data at speeds in excess of 160 Mbps to consumers and at 120 Mbps or more upstream from consumers.
DOCSIS 3.0 also incorporates support for the Internet Protocol version 6. IPv6 is the next generation of the Internet Protocol and greatly expands the number of Internet addresses that cable operators may use, allowing them to provide consumers with more IP-based services, such as IPTV and a variety of telephony capabilities. These new protocols will allow cable operators to expand their service offerings without bound.
SG 9 has in the recent past begun the process of producing the second generation of standards known as IPCablecom. These standards, identified as PacketCable 2.0 in the U.S., provide the specifications for delivering advanced, real-time multimedia services over cable operators’ networks. They utilize the DOCSIS platform and Internet Protocol technology to enable a wide range of multimedia services such as fixed-mobile convergence, business communications, video communications, and cross-platform features.
The initial set of IPCablecom2 Recommendations, covering the core elements of the PacketCable 2.0 architecture, was consented by the study group in 2006. The additional standards consented during the Singapore meeting add Home Subscriber Server functionality to the architecture. The HSS provides key mechanisms needed to support subscriber mobility and roaming.
A new draft standard has been produced that defines service level requirements and an architectural framework for cable networks to provide new services based on technology generally known as Internet Protocol Television. IPTV utilizes the Internet protocol in providing video/audio/text/graphics/data at required levels of quality, security, interactivity and reliability. The new draft standard is extensive and includes requirements for network elements as well as CPE, including middleware application interfaces which consist of software libraries that provide uniform access to system services. It leverages existing deployed cable technologies, such as MPEG, DOCSIS, GEM, and IPCablecom to provide a smooth path for cable operators to integrate IPTV technology into their networks.

After interviewing Chris Kohler about the modems that passed CableLabs Cert Wave 58, it seemed only fair to talk with Motorola’s Mike Cookish as well about the bronze DOCSIS 3.0 qualification of Motorola’s cable modem termination system (CMTS). The interview is about 16 minutes long and fairly technical, so for those of you not interested in listening to the whole thing, there are a few choice quotes below the audio link.
On DOCSIS 3.0 speeds:
“Our customer J:COM in Japan on April 25th just launched a 160-megabit service.”
On DOCSIS 3.0 in the US:
“My expectation is that by the end of 2008, the top major operators [in the US]… will be in some form of deployment stage for channel bonding in most parts of their network.”
On the need for both greater overall upstream capacity and peak upstream bandwidth capacity
“The reality is that when operators really want to begin to deploy full-scale, widely-available, production-ready upstream channel bonding they’re going to need two things: they’re going to need to increase the capacity of the number of upstreams for fiber node or neighborhood, and then number two, they’re naturally going to need the DOCSIS 3.0 upstream channel bonding solution.
So in Motorola’s case, we’re working on the upstream portion of our decoupled I-CMTS solution called the RX32 that will provide 32 upstream channels per single card as well as upstream channel bonding, and it’s the two of these that we believe will give the operator the optimum mix of increased average capacity as well as increased peak bandwidth for channel bonding.”
