Headend station of cable modems ARRIS Cadant C3


Headend station Cadant C3 operates in standards DOCSIS 2.0, Euro-DOCSIS and Japanese-DOCSIS. It realizes features of service quality control (QoS), determined with standards CableLabs to arrange extended set of IP-services. The whole spectrum of possibilities to organize safety, determined by DOCSIS 2.0 and Euro-DOCSIS is maintained, as well as dynamical determination of quality of services and service flows, required for organization of such services like IР-telephony. СЗ CMTS maintains 10/100/1000 BaseT connection as per interface Ethernet, 64/256 QAM transmission in direct channel, QPSK or 8/16/32/64/128QAM modulation in return channel,.СЗ CMTS satisfies needs of the world market, realizing program-switched operation modes in standards DOCSIS, Euro-DOCSIS and Japanese-DOCSIS. All the modes allow operating at any frequency of return channel within range of 5-65 MHz Besides, additional bandwidth of return channel 6.4 MHz is maintained, that together with additional methods of division of return channel resource A-TDMA and S-CDMA gives possibility of creating symmetrical as per connection rate. Station is scaled with additional modules of receiver of return channel and maintains in maximum configuration up to 6 receivers of return channel per one direct channel.
