Interface - Telecom

LE88004KSC, which is short for Legerity 88T405KSC, is a family of Integrated Access Devices (IADs) intended for the telecom market. It includes integrated voice, fax, data and other functions. It combines all of the necessary analog access capabilities—POTS, T1/E1, ADSL/2/2+—for last-mile access. LE88004KSC provides basic VoIP functions such as Dual Talk/Dual Codec, Integrated Voice and Fax, Digital Data formatter/Modem (undedicated), FC-L2 and PRI Traffic Monitoring capabilities. This system ensures interoperability to all kinds of phone systems, even legacy systems, and allows VoIP to be deployed quickly and cost-effectively.

Application Field

This LE88004KSC technology is used in many different applications such as telephone systems, wireless networks, and media streaming. As a communication interface, it is used for POTS lines, digital subscriber line (DSL) phone services, and Voice over Internet Protocol (VoIP). The LE88004KSC is used for deploying DSL as part of a PSTN access network.

The LE88004KSC has been used by many telecommunications operators to build integrated access devices that can provide voice, fax, data, IP and other services using the same copper access link. For example, an operator can use the capacity of DSL to provide a range of services such as IP telephony, interactive multimedia and other advanced services over the same copper access link. This provides flexibility and cost-saving advantages.

Working Principle

LE88004KSC is based on a Broadband Access Platform (BBAP) technology with System-on-a-Chip (SoC) designs that make it possible to integrate various types of terminations onto a single platform. This technology is capable of providing whole-house integrated service delivery and can be used for the provision of different services over one access infrastructure such as voice, data, video and Internet access. The LE88004KSC is designed to be a last-mile network access solution for the deployment of integrated services over existing POTS and digital subscriber lines.

The working principle of the LE88004KSC is based on a two-tier architecture which supports both line-side and host-side applications. On the line-side, the LE88004KSC provides physical and data link layer interfaces for connection to the customer premises equipment (CPE). The host-side implements the functions required for management, control and operation of the line-side interfaces such as packet management and call control. In addition, the LE88004KSC can be used to provide a range of advanced services such as VoIP, video conferencing, streaming and other multimedia services.

LE88004KSC is a highly integrated system which enables broadband IP telephony services and internet access without relying on traditional telephone systems. The LE88004KSC is deployed in many regions to provide next-generation services including high speed data communication, virtual private networks and wireless connections. It is in use for a wide range of applications in private network, business, enterprise and carrier applications.
