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
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 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.
