Device Overview

Summary

The PM5309 TBS-2488 is a high performance backplane interface and cross-connect solution for 2.5G line cards in SONET/SDH systems.

Applications
• Multi-service Provisioning Platforms
• SONET/SDH Digital Cross-connects
• SONET/SDH Add/Drop and Terminal Multiplexers

Additional Features
  • Provides one low-speed parallel TelecomBus interface operating at 32 bits x 77.76 MHz
  • Provides three high-speed multi-rate serial backplane interfaces
  • Supports CLOS and memory-based switch fabric systems
  • Supports linear, UPSR, and BLSR protection strategies
  • Implements a 10G memory switch fabric with STS-1/AU-3 switching granularity in a single device
  • Supports non-blocking anycast switching between any of the serial or parallel interfaces
  • Provides two pages of connection memory with software and hardware controlled hitless page swaps at frame boundaries
  • Provides integrated delay management that allows for arbitrary SONET/SDH frame alignments on each ingress serial link
  • Supports three RASIO 3G high-speed serial backplane interfaces for interfacing with SONET/SDH cross-connects, framers, mappers, and other TBS-2488 devices
  • Each high-speed serial backplane interface is capable of independent operation at 4x622 Mbit/s scrambled NRZ SONET/SDH, 4x777 Mbit/s Serial TelecomBus, or 1x2488 Mbit/s scrambled NRZ SONET/SDH
  • Supports one 32-bit or four 8-bit 77.76 MHz TelecomBus interfaces to interface with parallel TelecomBus framers and mappers
  • Integrated pointer interpreter reduces complexity of external framers and mappers by asserting payload, J0, and J1 indications on the outgoing TelecomBus interface
  • Allows insertion and extraction of TOH bytes through a dedicated low speed serial interface
  • Low power 1.2 V CMOS core with 2.5 V or 3.3 V CMOS/TTL selectable digital I/O
  • Generic 16-bit microprocessor bus interface and full suite of interrupts for configuration, control, and status monitoring
