) today announced the production release of the CHESS(TM) III and CHESS(TM) Wideband chip sets for next-generation Multi Service Provisioning Platforms (MSPPs) and digital cross connects. PMC-Sierra's CHESS III and CHESS Wideband products have achieved over one hundred design wins with leading manufacturers around the world. Major equipment manufacturers such as Alcatel, Lucent, ZTE ZTE Zalaegerszegi Torna Egylet (Hungarian sports club) , and many others use PMC-Sierra's solutions to enable next-generation metro transport equipment.

The highly integrated CHESS III and CHESS Wideband chip sets --

--Enable Original Equipment Manufacturers (OEMs) to design highly integrated, scalable metro transport solutions with reduced power, cost and complexity

--Improve fiber efficiency and reduce carrier deployment and operational costs for Service Providers by distributing grooming capabilities into every network element

CHESS III chip set for aggregating, grooming, and transporting 2.5Gbps and 10Gbps metro services

CHESS III is the foundation chip set used to build the new generation of metro transport equipment. It offers a wide range of STS-1/AU-3 cross-connect solutions as well as highly integrated framer solutions.

CHESS III introduced leading edge technology innovations including --

--Message Assisted Protection Switching (MAPS)

--Scalable single stage cross-connect solutions using bit-slicing

--Best In Class TFI-5 high speed serial backplane technology, Rate Agile Serial I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output.

I/O - Input/Output

The CHESS III chip set consists of the following devices:

TSE-Nx160 - 64-port cross-connect device that enables single stage non-blocking cross-connects to scale from 160 Gbps to 640 Gbps

TSE See Tokyo Stock Exchange.


1. See Tokyo Stock Exchange (TSE).

2. See Toronto Stock Exchange (TSE).
 240 - 96-port cross-connect device that reduces the software complexity of automatic protection switching using MAPS(TM) technology

TSE 120 - 74-port cross-connect device optimized for lower bandwidth, lower cost applications

ARROW-2x192 - highly integrated channelized Refers to an architecture that transmits data in channels. It often refers to the 64 Kbps channels in T1 lines, which were originally developed to handle digitized voice streams (TDM). See TDM.  20Gbps framer that supports 8 ports of OC-48/STM-16 or 2 ports of OC-192/STM-64

ARROW-1x192 - highly integrated channelized 10Gbps framer that supports 4 ports of OC-48/STM-16 or 1 port of OC-192/STM-64

CHESS Wideband chip set for VT/TU VT/TU Virtual Tributary/Tributary Unit  grooming

The CHESS Wideband chip set is a highly integrated VT/TU grooming solution that enables cost-effective in-service upgrades to MSPPs, digital cross-connect A network device used by telecom carriers and large enterprises to switch and multiplex low-speed voice and data signals onto high-speed lines and vice versa. It is typically used to aggregate several T1 lines into a higher-speed electrical or optical line as well as to distribute signals  systems and Add/Drop Multiplexers. The chip set enables Service providers to cost-effectively manage both new 10/100 Ethernet services and existing T1/E1 services at the VT/TU granularity.

The CHESS Wideband chip set consists of the following devices:

WSE WSE Web Services Enhancements (Microsoft)
WSE Warsaw Stock Exchange (Warsaw, Poland)
WSE Symposium on Web Site Evolution (IEEE International Symposum) 
 40 - 18-port wideband cross-connect, device that reduces the software complexity of automatic protection switching using MAPS(TM) technology

WSE 20 - 10-port wideband cross-connect device optimized for lower bandwidth, lower cost applications

TUPP TUPP Tobacco Use Prevention Program  9953 - SONET/SDH tributary unit payload processor for 9953 Mbit/s

Broad Portfolio Enables True Multi-Service Provisioning Platforms (MSPPs)

To improve the carrier networks' underlying structure and economics, MSPPs must offer a complete set of Time-Division-Multiplexers (TDMs) -- OC-3/STM-1, OC-12/STM-4, DS3/T3/E3, T1/E1 and new Ethernet client interfaces. PMC-Sierra's extensive transport product family enables complete solutions and accelerates time to market.
