Terayon Communication Systems which claims to be a leading provider of broadband solutions has announced that its TJ 720x cable modem was certified to meet the European Euro-DOCSIS 1.1 (Data Over Cable Service Interface Specification) cable data specification by tComLabs, a laboratory commissioned by the Euro-DOCSIS Certification Board.

In addition to being Euro-DOCSIS 1.1 certified, the TJ 720x is also Euro-DOCSIS 2.0 based as it includes the S-CDMA (Synchronous Code Division Multiple Access) and A-TDMA (Advanced Frequency Agile Time Division Multiple Access) advanced physical layer technologies selected for the new specification.

An official release informs that several European cable television operators have already deployed the TJ 720x operating in Euro-DOCSIS 1.1 mode, and the modem is in field trials with several other operators in Euro-DOCSIS 2.0-based mode. In Euro-DOCSIS 2.0-based mode, the TJ 720x enables European cable operators to deliver new revenue-generating broadband services to their subscribers, including videoconferencing, cable telephony, online gaming and peer-to-peer networking.

This is possible because Euro-DOCSIS 2.0 supports up to three times the upstream data throughput of Euro-DOCSIS 1.1, enabling broadband services that require substantial two-way bandwidth the release states.

Terayon's end-to-end Euro-DOCSIS 2.0-based cable data system has three components: the TJ 720x cable modem, the BW 3500 or BW 3200 model CMTS (Cable Modem Termination System) and the TMC (Terayon Management Center) network management software. In a system configuration, TJ 720x modems are installed in individual subscribers' homes and interoperate with a BW 3500 or BW 3200 CMTS deployed in a cable operator's headend -- the central point of a cable network, states the release.

The BW 3500 is a scalable, carrier-class CMTS for operators' most demanding broadband applications, and is the only CMTS qualified to meet the North American DOCSIS 2.0 and PacketCable 1.0 specifications. Complementing the BW 3500 is the compact BW 3200, which is suited for smaller cable systems or large systems that are segmented.

The final component of Terayon's Euro-DOCSIS 2.0-based cable data system is the TMC network management system. It is a single, integrated software solution for managing, configuring and provisioning Terayon's CMTSs and any DOCSIS modem, enabling operators to easily support multiple ISPs and offer tiered levels of service. It has advanced fault management, performance monitoring and network troubleshooting features to provide operators with greater visibility into the "last mile" of their networks.
