BURNABY, British Columbia--(BUSINESS WIRE)--March 5, 2001
New FREEDM(TM) Products Provide 4 Times Density Improvement for
PMC-Sierra (Nasdaq:PMCS) today announced two new members of its FRame Engine and Datalink Manager (FREEDM(TM)) packet processor family: the PM7388 FREEDM-336A1024 and the PM7389 FREEDM-84A1024.
The FREEDM-336 is the industry's first packet processor to support up to 336 T1 lines and achieve a sustained wire speed throughput for short IP packets. The FREEDM-336 also supports up to 252 E1 links and is ideal for channelized nxOC-12 and OC-48 port card designs in edge routers, optical access equipment and multiservice switches (Figure 1). The FREEDM-84 supports up to 84 T1 or 63 E1 links over 1024 HDLC channels and is ideal for nxDS3 and nxOC-3 port card designs. By integrating a dedicated multilink packet processor engine, the new FREEDM devices provide greater than 4 times the density achievable with previous CPU and FPGA solutions.
Multilink Technology Bridges the Bandwidth Gap between T1/E1 and T3/E3
The explosive demand for high data rate applications is pushing the WAN bandwidth requirement for many business users beyond the capability of a single T1/E1 link. The next service level above T1's 1.544 Mbit/s is a large jump to the 45 Mbit/s T3 that has limited deployment in the access network and may not offer users with the bandwidth relief at the target price point. Multilink Point-to-Point Protocol (ML-PPP) and Multilink Frame Relay (ML-FR) are standard compliant solutions designed to bridge the bandwidth gap between T1/E1 and T3/E3 by supporting dynamic bandwidth allocation in multiple T1/E1 rates.
Early implementations of ML-PPP and ML-FR relied on large and complex FPGA, ASIC, or processor-based implementations. Network system architects can now leverage the standard compliant ML-PPP and ML-FR capabilities of the new FREEDM products to develop a single design that support rates ranging from DS0, T1/E1, multilink T1/E1 bundles to unchannelized DS3, at greater than 4 times the density than previously achievable (Figures 2 and 3).
"PMC-Sierra's commitment to lead the industry in highly channelized packet processor solutions is critical for us to deliver the necessary port density in our next generation ERX-1400 Edge Routing Switches," said Kurt Melden, chief technology officer at Unisphere Networks. "The density improvement provided by FREEDM-336 allows us to meet the large scale demands for edge-enabled services," concluded Melden.
The FREEDM-336 and FREEDM-84 expand PMC-Sierra's multiservice architecture. Together, with PMC-Sierra's SPECTRA(TM) (SONET), S/UNI(R)-IMA (ATM inverse multiplexor), TEMUX (AAL1 voice-over-ATM), AAL1gator(TM) (voice-over-IP/ATM processor) and MECA(TM) product families, a single design can support all of the major protocols at the edge of the network (Figure 4). This chip set satisfies the physical and power constraints found in the newest edge router and switch equipment. A complete channelized OC-48 or 4xOC-12 solution requires only a single SPECTRA-2488, 16 TEMUX-84s and 4 FREEDM-336s. Such designs can be rapidly brought to production by applying the software and hardware knowledge gained from the hundreds of previous generation designs based on the FREEDM family (Figure 5).
"Leveraging the ubiquitous copper access infrastructure is a major initiative of service providers today," said Glenn Bindley, general manager and vice president of PMC-Sierra's Access Product Division. "By incorporating Multilink technologies, the FREEDM-336 and FREEDM-84 provide unprecedented line card functionality and densities for next generation IP routers and optical switches," concluded Bindley.
