The ARROW 2488 consists of a SONET/SDH network interface and framer with integrated SERDES including full section, line, and high-order path processors, non-blocking memory-based high-order STS/AU and low-order VT/TU cross-connect, low-order VT/TU path processors, and a large number of expansion interfaces (both ESSI serial links and a Parallel TelecomBus interface). The SONET/SDH framer, high-order cross-connect, and low-order cross-connect support Message Assisted Protection Switching (MAPSTM), a mechanism that allows standards-based protection switching without software intervention. Additional Features Optimizes compact multi-port OC-48/STM-16 architectures, while allowing scalability to multi-port OC192/STM-64 applications Integrates eld-proven CHESSTM intellectual property, reducing development cycles through reuse of CHESS software base Exceeds the requirement for 50 msec protection switching for up to 5376 tributaries using a fully hardware-based APS algorithm (MAPS) Two groups of four SONET/SDH interfaces, each supporting two modes of operation: Quad OC-12/3/STM4/1 mode (four interfaces operating at 622.08 Mbit/s or 155.52 Mbit/s, selectable per port) Single OC48/STM-16 mode (one interface operating at 2488.32 Mbit/s) Quad OC-12/3/STM-4/1 mode (four interfaces operating at 622.08 Mbit/s or 155.52 Mbit/s, selectable per port) Single OC-48/STM-16 mode (one interface operating at 2488.32 Mbit/s) CML compatible serial interfaces to connect to optical transceivers Framing, high order pointer processing, alarm processing and overhead processing on all received network streams Dedicated pins to extract/reinsert B3/N1 path overhead bytes for Tandem Connection Monitoring Per-framer connection ID message, allowing veri cation of high order path connectivity across single or multistage fabrics BLSR and MSSPRing protection switching with alarm processing, K-byte express, automatic payload con guration, and other features Insertion/extraction of transport overhead (TO) bytes from the line side interface High capacity, memory-based, HO cross-connect capable of switching at STS-1/AU-3 granularity Floating delay management One 32-bit or four 8-bit 77.76 MHz TelecomBus interfaces connecting to parallel TelecomBus framers and mappers Cross-connect implements HO MAPS algorithm to extract, lter and interpret line status code on a per STS1 basis TOH byte insertion and extraction (99 TOH bytes per port) Support for a set of active and standby con guration memory pages, permitting new switch settings to be updated in one page while the TSE operates from the control settings of the other page 2.5 Gbit/s to/from 622 Mbit/s interleaving/de-interleaving Muxing scheme enables di erent port asset allocations for di erent applications Con gurable, multi-channel, payload processor that aligns and monitors performance of the SONET virtual tributaries (VTs) or the SDH tributary units (TUs) Optionally monitors and terminates the path overhead of any legal mix of HO payloads in a SONET/SDH stream Remaps the incoming transport frame, payload frame and tributary multi-frame alignment on the Receive side to the VT/TU Cross- Connect (WSE) frame and multi-frame alignments through low order pointer processing Drop/Add path of TUPP supports multiple SDH payload conversions Memory-based, LO cross-connect capable of switching at VT/TU granularity Accepts and switches SONET VT and SDH TU streams.
