S4806CBI Datasheet | AMCC

Features - Provides two SONET/SDH line interface modes of operation: single STS-48/STM-16 or quad STS-12/STM-4s. - Processes any valid bination of SONET/SDH STS-48c/ AU-4-16c, STS-12c/AU-4-4c, STS-3c/AU-4, or STS-1/AU-3 tributaries within an STS-48/STM-16 or STS-12/STM-4. - Terminates/generates SONET/SDH section, line, and optionally path overhead. SONET/SDH processing of all defined TOH/POH bytes, pliant with Bellcore GR-253 and ANSI T1.105, and ITU G.751, G.783, G.804. - Performs full-duplex mapping ATM cells or packets for up to 48 payload tributaries. These tributaries can range in size from STS-48c/AU-4-16c down to STS-1/AU-3. - Supports full-duplex mapping of ATM cells or packets into DS3 tributaries for ATM over DS3 or packet over DS3 applications. DS3 tributaries are then mapped into either STS-1s or STM-1s via AU-3. - ATM mapping is pliant with the ATM Forum UNI 3.1 specification and ITU-T I.432.1 and I.432.2. - POS mapping is pliant with IETF RFC 2615. - Supports simultaneously ATM, POS, TDM and direct-mapped traffic on a per tributary basis. - Provides a single 4x622 MHz tele bus type system interface for add/drop of payload tributaries containing TDM traffic. This interface includes a 144x48 STS-1 level crossconnect for grooming of TDM tributaries. - Alternatively, this TDM port can be used to support protectionswitching configurations between two OHIO devices or two fiber optics modules. - This 4x622MHz APS/TDM drop/add interface supports both synchronous and asynchronous operation. - Built-in 144x48 cross-connect capability in the TX direction. Supports ring architectures such as add-drop, drop and continue, and hairpinning, as well as APS. - Provides a four bit 622 MHz line interface on the SONET/SDH side for STS-48/STM-16 applications; four serial 622 MHz signal for STS-12/STM-4 applications - Supports independent loop timing in quad STS-12/STM-4 line configuration - Provides a 100 MHz 32-bit Flexbus-3TM system interface; supports Utopia Level 3...
