Coaxial Data Networt or EOC

LE21 Coaxial Data Network comprises of a Coaxial Line Terminal (CLT) at the Optical Node which is already installed in the neighbourhood and a Coaxial Network Unit (CNU) at homes. CLT enables multiplexing CATV and wide band data. CNU demultiplexes these two streams at home. LE21 CDN bridges the gap between the two existing media types and facilitates migration to a unified Ethernet based architecture. IPTV, Video Telephony and high speed Internet and gaming are example applications that are driving the need for Ethernet in the subscriber network access space.
LE21 CDN has been designed to minimize the expenses associated with upgrading existing Hybrid Fiber Coaxial Network to start offering such services. LE21 CDN uses technologies that are quite different from the earlier set of technologies used by Ethernet over Coax that were designed more for home networking. The new technologies give it higher speed and much more robust performance when deployed in the coaxial access networks.

LE21 CDN is based on Creado 8800 ASIC that utilizes latest communication technologies like OFDM (Orthogonal Frequency Division Multiplexing) and LDPC (Low Density Codes). These technologies give it the same robust modulation behavior as DOCSIS 3.1 (the latest implemented version of the popular standards). However it achieves the same at remarkably lower cost.LE21 CDN provides access wirespeed of 480Mbps. It occupies Low Frequency Band under 88 MHz and has no overlap with the prevalent CATV system frequencies.

LE21 CLT can connect up to 31 EoC Slaves (CNUs). LE21 CDN supports Remote Network Management. Operators can use LENS (Logic Eastern Network Supervisor) product for managing the entire networks intelligently. LENS also generates intelligent alarms to enable operators to take proactive action.
LE21 CDN based systems provide an ideal method to Multi System Opertors and Internet Service Providers to start offering Triple Play Services and hence increase their revenue and profitability.
