Product Overview

This product brief describes the UFE412, the leading device in PMC-Sierra's Universal Front End 4 (UFE4) product family in terms of features, port density and performance. The UFE412 is a preconditioning co-processor for WinPath3-based Applications targeted for Wireline and Wireless Backhaul Solutions. Together, the WinPath3 and the UFE412 create a platform that enables highly integrated solutions for a range of port densities and bandwidth configurations scaling to 4xOC-3/STM-1 rate with full APS 1+1 redundancy. The UFE412 device enables the WinPath3 to efficiently support a variety of services: TDM, ATM, HDLC, PPP, and Circuit Emulation. The WinPath3 itself also supports many protocol interworking services, including CES over PSN, ATM over PSN, IP interworking (routing), ATM cell switching, IMA, ML-PPP and others. The WinPath3/UFE412 platform allows maximum flexibility and feature richness together with efficiency in cost, power and board space. There are two variants of the UFE412: the UFE412-T4 is optimized for CESoP/SAToP applications, while the UFE412-M4 provides multi-protocol support.
