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/detection and bit interleaved parity processing. The SONET/SDH transmit and receive blocks are used to transmit/receive an OC-48c/STM-16c signal or compose and decompose four OC-12/12c signals. The blocks operate at a peak internal clock speed of 77 MHz and support 32-bit internal data paths. The transmit and receive blocks are compliant with both SONET and SDH standards.
