L DESCRIPTION The XRT95L51 is an ATM/PPP physical layer processor with integrated SONET OC-48/STM-16 framing controller. ATM direct mapping and cell delineation are supported, as are PPP mapping and frame processing. The XRT95L51 contains an integral SONET framer which provides framing and error accumulation in accordance with ANSI/ITU-T specifications. The configuration of this device is done through internal registers accessible via 8-bit parallel, memory mapped, microprocessor interface. The XRT95L51 provides full section, line and path overhead processing and supports scrambling/descrambling, alarm signal insertion/det
