SUNNYVALE, Calif. -- Maxim Integrated Products (Pink Sheets: MXIM) introduces the DS33X162, the first product in a Company's family of new Ethernet mapping solutions. The DS33X162 is a highly integrated Ethernet-over-PDH (EoPDH) mapping device that enables the delivery of new Carrier Ethernet services over the existing PDH telecommunications infrastructure. The device's configuration is extremely flexible for ease of design. It allows Ethernet transport from a single GbE or dual 10/100 Ethernet interfaces, and supports up to 16 T1/E1 links or 8 DS3 links with over 400Mbps throughput. The DS33X162 thus covers the complete range of configurations defined in the EoPDH standards.

Overcoming Traditional Ethernet Mapping Challenges

Prior to the DS33X162, designing equipment to utilize the full range of the ITU EoPDH standards required the use of complex NPUs or costly field-programmable gate arrays (FPGAs).

NPU solutions require software to process each Ethernet frame in the data path, leading to service outages when software errors occur. The DS33X162's data and control plane separation removes the need for software to process the data path, but still allows software interaction for management and value-adding functions.

FPGAs are expensive and power-hungry. FPGA solutions with features and capabilities comparable to the DS33X162 cost up to 2x more and require 3x to 4x the power.

Other integrated ASIC solutions do not have the throughput, scalability, and breadth of features of the DS33X162. Some ASICs even require expensive NPUs to perform Operation and Maintenance (OAM) functions. Advancements over previous solutions include QoS, VLAN tagging, and hardware support for Ethernet OAM-all at less than 1W in most applications.
