CS61575-IL1 Line Interface Support for T1 and E1 Systems

CS61575-IL1 is designed for telecom equipment that needs a dedicated line interface for T1 and E1 applications. It fits network access hardware, transmission cards, and service replacements where line-side performance must stay aligned with the existing platform. CS61575-IL1 supports T1 and E1 line interface functions in a 28-pin PLCC package, making it a practical option for boards that need to retain the original interface design. It is useful in installed communications systems where a full redesign is not practical but the line-side section still needs a correct replacement part. CS61575-IL1 helps preserve board function in repair, maintenance, and controlled production work tied to long-life telecom hardware. Use CS61575-IL1 to support established T1 and E1 systems.
