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
