Product Summary

The HC55185GCR is a ringing subscriber line interface circuit (RSLIC). The device supports analog Plain Old Telephone Service (POTS) in short and medium loop length, wireless and wireline applications. Ideally suited for remote subscriber units, the HC55185GCR offers flexibility to designers with high ringing voltage and low power consumption system requirements. The applications of the HC55185GCR include Voice Over Internet Protocol (VoIP), Cable Modems, Voice Over DSL (VoDSL), Short Loop Access Platforms, Remote Subscriber Units and Terminal Adapters.
