AMCC First to Enable the Next Generation Multi-Carrier, Transparent Network Architecture With Introduction of 10 Gbps Digital Wrapper and FEC Device
AMCC's Hudson is the Industry's First Device to Meet the Rapidly Growing Demand for 10 Gbps Digital Wrapper Solutions From the Man, Transport and WDM Sectors
SAN DIEGO--(BUSINESS WIRE)--Dec. 11, 2000-- Applied Micro Circuits Corp. (AMCC) (Nasdaq:AMCC - news), a leader in high-bandwidth silicon connectivity solutions for the world's optical networks, today announced the Hudson (S19203), the industry's first 10 Gbps silicon device architected to support both the evolving G.709 digital wrapper standard and traditional SONET/SDH infrastructures.
The Hudson variable rate, digital wrapper framer/deframer and performance monitor device facilitates the transparent transport of multiple protocols across the network, while aiding interconnection between multiple carriers. Hudson incorporates programmable Forward Error Correction (FEC) for rates up to 10.66 Gbps and supports OC-192 transmission standards. The digital wrapper technology provides an extension of the current SONET/SDH infrastructure, while enhancing both flexibility and transparency across the network. The Hudson easily interfaces with AMCC's 10 Gbps mux/demux devices, SONET/SDH/digital wrapper backplane devices and AMCC's mapping and pointer processing devices.
``The digital wrapper is the next important step for large optical networks as it incorporates the best features of SONET/SDH while removing some of the rigid overhead structure that makes SONET/SDH sub-optimal for an IP-centric, intelligent optical network,'' said Brent Little, vice president of marketing for AMCC. ``By using key devices such as Hudson, OEMs will now be able to create more efficient and interoperable systems without starting from scratch.''
AMCC's digital wrapper design has already been adopted by most of the major wide area networking (WAN) equipment manufacturers. The demand for digital wrapper products stems from the need in the WAN to transparently transport multiple protocols at 10 Gbps, coupled with the need to efficiently provision bandwidth across today's multiple-carrier network.
``The Hudson is built for the next-generation multi-carrier transport network architecture and ushers in an efficient and cost-effective means of transporting traffic while extending existing SONET infrastructures,'' said Ken Prentiss, AMCC's director of marketing for telecom products. ``We are seeing unprecedented demand for Hudson across a large customer base due mainly to the device's flexible architecture; customers can wrap, unwrap or monitor traditional SONET/SDH traffic, or wrap and unwrap IP or any other traffic using a single device.''
The digital wrapper concept involves grouping together a number of existing frames into ``super-frames,'' which can then be more efficiently managed with a relatively small allocation of overhead-per-byte of data. By aggregating together the provisions for ``framing bits'' that are already defined for use by existing time-division multiplexed (TDM) structures, the super-frame concept allows for the implementation of an intelligent operation, administration and maintenance (OAM) capability without materially expanding the amount of data currently being transmitted. This creative use of available control bits also allows FEC functions to be very efficiently incorporated within the digital wrapper definition without a significant net increase in overall bandwidth usage.
The Hudson's core logic runs on a 1.8V power supply and features two input and two output ports, which are configurable in many ways. Figure 1 shows a typical network application supporting a single data stream with dual redundant input and output lines. The input and output ports can be configured as a dual redundant I/O on a single data stream for protection switching or as two completely independent data streams for duplex operation. Either input port can be directly connected to either output port for loopback testing.
The Hudson provides full digital wrapper performance monitoring and features Optical Channel Overhead (OCh-OH) insertion and extraction, which are independently controllable. All 64 OCh-OH bytes in a superframe are programmable in function and are available for insertion from and drop to FPGA or microprocessor. Data entering and leaving the Hudson device can be optionally differentially decoded and encoded, deframed and framed, descrambled and scrambled, and decoded and encoded with FEC information. In addition, SONET data can optionally be performance monitored for integrity, alarms, and trace messages.
Pricing and Availability
The Hudson (S19203), packaged in a 624-pin CBGA, will be sampling to development partners in December with volume production commencing in Q2 2001. AMCC solution set pricing can be obtained from the company by calling 800/755-AMCC (800/755-2622). |
