Its goal is to reduce system level costs, space, and power through higher levels of integration, and to reduce the total cost of ownership by offering better quality of service. The Le9502 RSLIC device provides a totally configurable solution to the BORSCHT functions for two lines. The resulting system is less complex, smaller, and denser, yet cost effective with minimal external components.
