S4806CBI
Overview
- Provides two SONET/SDH line interface modes of operation: single STS-48/STM-16 or quad STS-12/STM-4s.
- Processes any valid combination 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, compliant 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 compliant with the ATM Forum UNI 3.1 specification and ITU-T I.432.1 and I.432.2.
- POS mapping is compliant with IETF RFC 2615.
- Supports simultaneously ATM, POS, TDM and direct-mapped traffic on a per tributary basis.
- Provides a single 4x622 MHz telecom 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.
