Matterhorn
System-on-Chip Metro ADM

Overview

Matterhorn is a system-on-chip solution for OC-48 and STM-16 Metro Add/Drop multiplexers with multi-rate SONET/SDH line interfaces, higher and lower order cross connect, integrated timing and clocks and multiple tributary ports.

Typical applications include Line and tributary cards for Next-gen SONET/SDH MSPPs and DWDM systems, and OC48/STM-16 microADM or Optical Edge Device systems.

Line Interfaces

  • 2 STM-16/4/1, OC-48/12/3 triple-rate interfaces
  • 16 STM-4/1, OC-12/3 dual-rate interfaces
  • Direct interface to multi-rate SFP modules

Backplane Interfaces

  • 4 TFI-5 or 16 622Mb/s for interface to mate devices or tributary cards

Features

  • Line and section Byte processing functions
  • Integrated clock data recovery and scrambling on all ports
  • 28.5 Gb/s AU4/STS1 Higher Order crossconnect (549 STS1, 183 VC4)
  • 7.5 Gb/s VC12/VT1.5/VC3 Lower Order crossconnect (4032 VT1.5, 3024 VC12, 144 LO-VC3)
  • Hardware assisted UPSR/SNC protection switching for VT1.5, VC12 and LO-VC3
  • SONET/SDH pointer processing, overhead termination and protection schemes
  • Contiguous Concatenation for VC-4-16c, VC-4-4c, STS-48c, STS-12c and STS-3c
  • AIS, Unequipped and PRBS generators and monitors
  • G.813 SEC, GR-1244 Stratum-3 network element timing
  • 2MHz, E1 and DS1 timing interfaces
  • 4 E1/DS1 ports
  • Telecom bus 8-bit, 155 or 622Mb/s
  • Flexible SONET/SDH overhead access ports
  • Access to backplane overhead Bytes
  • Access to 48 DCC channels
  • HDLC based in-band management channels via DS1 or E1
  • Performance monitoring
  • Fault management
  • Loopbacks
  • 32-bit controller interface

Applications

  • Metro Add/Drop Multiplexer or MSPP with multiple OC-48/STM-16 ring closures
  • Line card: dual OC-48/STM-16 ports with mate and tributary interfaces
  • Tributary card: 16 port triple-rate SONET/SDH card with redundant backplane interfaces
  • Single chip OC-48/STM-16 micro MSPP in ring or terminal configuration
  • OC-48/STM-16 protected network termination device or OED
  • DWDM optical transponder with OC-3/12/48 aggregation and ring add/drop
