CSX - Family

G.SHDSL.bis and EFM Copper Modems: 1-2-4-Pairs

The CSX product family provides high speed transmission on copper lines, based on DSL technique. It provides affordable, flexible and efficient service provisioning for SME and SOHO customers as well as campus applications. Several different user interfaces can be ordered to provide solution from Internet access (Ethernet / EFM) to legacy services as machine-to-machine applications (V.24). The DSL side of the CSX-family is using standard telephone lines (UTP) for transmission and several lines can be bundled to achieve data-rates of up to 20Mbps across several kilometers. A powerful repeater (BRX1) is available to extend the operating distances massively.

The CSX family is fully-managed and can be operated in the ax chassis as well as in the single-slot housing. Inband management of remote units makes supervision and configuration very easy and comfortable. Together with the management infrastructure of the chassis, web-GUI, SNMP and ssh/telnet is available to integrate the devices into NOC.

G.SHDSL is the best solution to quickly provide cost-effective, high speed network service for SME and SOHO users who need symmetrical connections, either Internet or legacy. By utilizing the existing telephony infrastructure, installation is simple and straightforward. With up to 20 Mbps full duplex speed IP telephony, web hosting and various broadband services can be easily provisioned.
