On the high-speed side, it interfaces to a STS-192/ STM-64 signal in each direction. On the low-speed side, it interfaces to four STS-48/STM-16 signals in each direction. The S19201 can be used in conjunction with AMCC’s RHINE, MISSOURI, or DANUBE chips for terminating STS-48/STM-16 payloads. In the multiplex direction, the S19201 accepts four 16-bit parallel STS-48/STM-16 (155 Mb/s) signals. The S19201 locates the STS-48/STM-16 frames, descrambles the data, processes the TOH bytes (or SOH bytes in SDH mode), muxes the four STS-48/STM-16 tributaries. This muxed signal, or the STS-192 from the demux input is then selected as the input to the FRGEN192. The S19201 then generates the TOH bytes (or SOH bytes in SDH mode), performs frame synchronous scrambling, and out- puts the data onto a 16-bit bus. In the demultiplex direction, the S19201 accepts a 16-bit wide STS-192/STM-64 signal. The S19201 locates frame in this signal, performs descrambling, and processes the TOH bytes. This signal is then selected for disinterleaving. The four tributaries are then output on four 16-bit parallel interfaces. A TOH/SOH interface provides direct add/drop capability for both Section and Line overhead. On the multiplex side the S19201 generates section and line overhead. It performs framing pattern insertion (A1, A2), scrambling, alarm signal insertion, and generates sec- tion and line Bit Interleaved Parity (B1/B2) for far-end per- formance monitoring. On the Demux side the S19201 processes section and line overhead. It performs framing (A1, A2), descrambling, alarm detection, bit interleaved parity monitoring (B1/B2), and error count accumulation for performance monitoring. High-Speed Interface On the high-speed side, the S19201 supports 16-bit paral- lel high-speed interfaces, operating at 622 MHz, on both the multiplex and demultiplex side. Low-Speed Interface On the low-speed side, the S19201 supports four 16-bit parallel high-speed interfaces operating at 155 MHz.
