Overview

  The ever changing telecommunication environment in the new open global market has brought tremendous pressure on the pricing policies of telecommunication services. The only way to compete in the new environment is to synchronize prices and improved services.

  To survive in this ever evolving environment, Corecess has devised a new paradigm in the leased line and the VPN market through the full utilization and capabilities of the Corecess 6724. Corecess 6724 provides guaranteed services in the access network that can be used efficiently as leased line services for enterprises. Corecess 6724 also simplifies the network, and further enhances efficiency and flexibility through a Fast Ethernet up-link interface.

  Service providers can cover a broader service area with Corecess 6724; the most advanced CO (Central Office) SHDSL based equipment. It greatly enhances service availability being fit for the leased line service environment.

  Corecess 6724 provides a full-duplex symmetric service for end users or enterprises through G.SHDSL DSLAM based technology. It uses low frequency signal and consumes low power to control the instability that arise in copper lines, so as to be able to cover larger distances.

  Corecess 6724 provides 24 SHDSL lines and performs the required functions for Internet access service for enterprises. Corecess 6724 provides data rates of up to 2.3 Mbps in symmetric DSL service for up to 8Km coverage.
