PMC-Sierra Introduces the Industry's Highest Density Devices for Converging Voice, Data and Video onto Multi-service Networks.Business Editors/High-Tech Writers NOTE TO MEDIA: Photo and figures are available in a Smart News Release(TM) on Business Wire's Home Page at www.businesswire.com BURNABY, British Columbia--(BUSINESS WIRE)--Jan. 24, 2000 New AAL1gator(TM) ATM Adaptation Layer 1 (AAL (ATM Adaption Layer) The part of the ATM protocol that breaks up application packets into 48-byte payloads which become ATM cells when the 5-byte headers are attached. The AAL resides between the higher layer transport protocols and the ATM layer. 1) SAR (Segmentation And Reassembly) The protocol that converts data to cells for transmission over an ATM network. It is the lower part of the ATM Adaption Layer (AAL), which is responsible for the entire operation. See AAL. SAR - segmentation and reassembly devices provide up to six times the density of previously available solutions PMC-Sierra (Nasdaq:PMCS PMCS PMC Sierra (stock symbol) PMCS Project Management Control System PMCS partial mission-capable, supply (US DoD) PMCS Preventive Maintenance Checks & Services PMCS Professional Military Comptroller School ) today announced three new members of its AAL1gator family of high density constant bit rate ATM processors -- the PM73122 AAL1gator-32, the PM73123 AAL1gator-8 and the PM73124 AAL1gator-4. This comprehensive line of AAL1 Segmentation And Reassembly segmentation and reassembly - segmentation (SAR) solutions allows designers to develop next-generation networking equipment that aggregates multiple channels of voice, data and video traffic on a single ATM multi-service network. The AAL1gator devices can convert up to 32 lines of T1/E1/T3/E3 traffic into ATM, providing up to six times the density over other available solutions. Convergence of Carrier Voice and Data Networks Reduces Costs To reduce overall equipment and network operating costs operating costs npl → gastos mpl operacionales , incumbent carriers are seeking ways to migrate their separate circuit switched voice and leased line T1 networks onto a single ATM multi-service network. The ATM AAL1 protocol is uniquely capable of meeting the required quality of service for transport of voice traffic. The AAL1gator product family supports the complete suite of AAL1 standards including processing for individual 64 Kbit/s voice channels (structured mode) and processing of complete T1/E1/T3/E3 data or video channels (unstructured mode). The AAL1gator-32 targets convergence of high capacity T1/E1 over SONET/SDH interfaces on ATM multi-service switch port cards. The AAL1gator-8 is ideal for high density T1/E1 over copper interfaces on ATM Access multiplexer port cards, while the AAL1gator-4 is optimized for use in T1/E1 subscriber terminals for ATM Passive Optical Network (APON See PON. ) and Local Multi-point Distribution System (LMDS (Local Multipoint Distribution Service) A digital wireless transmission system that works in the 28 GHz range in the U.S. and 24-40 GHz overseas. It requires line of sight between transmitter and receiving antenna, which can be from one to four miles apart ) networks. PMC-Sierra and Tellabs Collaborate on Multi-Service T1/E1 over SONET/SDH Solutions &uot;We collaborated with PMC-Sierra to ensure the chip set met our system density goals,&uot; said Frank Melinn, Tellabs, Inc. senior staff engineer. &uot;The AAL1gator/TEMUX chip set supports the key interfaces and operating modes required for our AN-2100GX next-generation media gateway,&uot; concluded Melinn. Combining the new PM73122 AAL1gator-32 with PMC-Sierra's PM8315 TEMUX high density T1/E1 framer device provides an optimized solution for convergence of hundreds of T1/E1 lines onto a single port card. The AAL1gator-32/TEMUX chip set is ideal for ATM Multi-service Switches, Voice over ATM (VoATM) gateways, and Digital Access and Cross-connect (DACS DACS Data & Analysis Center for Software DACS Design and Analysis of Communication Systems (University of Twente, Netherlands) DACS Digital Access & Cross-Connect System DACS Data Acquisition and Control System (NASA) ) systems (see Figure 1 and 2). Pricing, Availability and Customer Support The PM73122 AAL1gator-32 is sampling now, packaged in a 35x35 mm 352-pin SBGA SBGA Striped Bass Growers Association SBGA Spreader Ball Grid Array SBGA Super Ball Grid Array and is priced at $299 in 1KU volumes. The PM73123 AAL1gator-8 and PM73124 AAL1gator-4 are each packaged in a 23x23 mm 324-pin PBGA PBGA Plastic Ball Grid Array and priced at $99 and $75, respectively, in 1KU volumes. All devices are rated for industrial temperature range operation (-40 to +85 degrees Celsius). All three new members of the AAL1gator product family feature a low power 2.5-volt core and support 5-volt compatible input/output signals. In addition, the new devices have been designed for ease of software upgrade for the hundreds of designs using previous generation AAL1gator products. A comprehensive customer support package including device datasheets, technical overview, hardware reference designs, application notes, models, software drivers and a software programmer's guide is available at http://www.pmc-sierra.com.

This radically improved link density is achieved through PMC-Sierra's Scalable Bandwidth Interconnect (SBI(TM)) bus. The SBI bus uses an 8 bit parallel format to interconnect the TEMUX Layer 1 framer device with high density Layer 2 solutions such as the AAL1gator-32. The AAL1gator-32 also provides H-MVIP and independent clock and data line interfaces for interconnecting to standard, non-SBI-compliant devices. Figure 3 illustrates the density benefits of the AAL1gator-32 by comparing two designs for a 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. DS3 AAL1 port card. The figure depicts use of current generation components versus a design employing the new AAL1gator-32 combined with the TEMUX. The AAL1gator-32 / TEMUX two-chip design replaces 12 individual components. This yields a lower cost per port, lower power per port using as little as one sixth the board space. &uot;PMC-Sierra developed the new AAL1gator devices to interface directly with the complete portfolio of complementary PMC-Sierra products including TEMUX, COMET, SPECTRA-155, SPECTRA-622, S/UNI-ATLAS and S/UNI-APEX,&uot; said Glenn Bindley, vice president of access products for PMC-Sierra. &uot;These synergistic devices provide a complete Circuit Emulation Service (CES) solution at densities ranging from a few to hundreds of T1/E1 lines,&uot; Bindley concluded.
