Catapult Announces Enhanced Support for ATM; Enables Testing For Advanced ATM Applications.Business Editors/High-Tech Writers MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--April 2, 2002 Catapult Communications Corporation (Nasdaq:CATT) today announced support for all of the commonly used lower level ATM protocols. DCT (Discrete Cosine Transform) An algorithm that is widely used for data compression. Similar to Fast Fourier Transform, DCT converts data (pixels, waveforms, etc.) into sets of frequencies. The first frequencies in the set are the most meaningful; the latter, the least. 2000(TM) users now have the ability to test an increased range of applications running over ATM. As telecommunication networks evolve to meet the demands made by 3G, the user services that must be supported are also becoming increasingly sophisticated. To support these new services, developers are asking for test systems for an increasing range of ATM implementations. Catapult has long provided support for 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. 5 (ATM Adaptation Layer 5) and AAL2. Catapult now offers support for AAL0 and will support AAL1 during the summer of 2002. AAL0 is a lower level protocol that provides a fast and transparent interface to the ATM cell, without adding any of the additional processing that the other AAL protocols incur. Proponents of AAL0 claim that this alternative provides increased flexibility and will pave the way for new varieties of ATM services. AAL1 can support time-sensitive applications that require a constant bit rate to run over virtual circuits. The DCT2000 is increasingly being used to test telecom equipment for 3G networks adhering to the 3GPP GPP Government Performance Project GPP General Purpose Processor GPP General Physical Preparedness GPP Gambian People's Party GPP Good Pharmacy Practice GPP Gross Primary Productivity GPP Green Procurement Program GPP Generic Packetized Protocol (TM) (UMTS (Universal Mobile Telecommunications System) The GSM implementation of the 3G wireless phone system. Part of IMT-2000, UMTS provides service in the 2 GHz band and offers global roaming and personalized features. ) and 3GPP2 (cdma2000) standards. Both types of networks employ ATM-based as well as IP-based protocols to support high bandwidth and high-speed multimedia services. By supporting AAL0, AAL1, AAL2, AAL5 and IP/AAL5, Catapult provides developers with a versatile and powerful solution for testing equipment built upon these foundations.
