Catapult Communications Enhances DCT2000 Test Capabilities.Business Editors/High Tech Writers MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Sept. 5, 2000 Catapult Communications (Nasdaq:CATT), a leading provider of advanced software-based test systems to the telecommunications industry, has enhanced the testing capabilities of the 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 for third generation (3G) cellular, voice over internet (VoIP) and enhanced data over mobile (GPRS (General Packet Radio Service) The first high-speed digital data service provided by cellular carriers that used the GSM technology. GPRS added a packet-switched channel to GSM, which uses dedicated, circuit-switched channels for voice conversations. ). A new software release expands the list of protocols and variants that support 3G/Broadband testing to more than 45 by adding: GTP GTP (guanosine triphosphate): see guanine. , NBAP, RANAP RANAP Radio Access Network Application Protocol (3GPP) RANAP Ran Application Part , FP, MAC, RLC RLC Residual lung capacity , ALCAP ALCAP Access Link Control Application Protocol (UMTS Signaling Layer, Q.2630.1) ALCAP Alabama Citizen Action Program ALCAP Access Link Control Application Part and STC. With the DCT2000, customers can now simulate or monitor both the voice and data transmissions across the 3G wireless networks. As a result, the DCT2000 enables manufacturers to verify the design and functionality of their products. Carriers benefit because the DCT2000 can confirm the interoperability between network components supplied by various manufacturers. In VoIP, Catapult now supports testing of over 20 protocols and variants. H.323 Annex E and H.248 (Megaco) encoding are now supported. H.323 Annex E is important for reliable communication over IP networks. The H.248 (Megaco) standard enables gateway devices to pass voice, video, fax and data traffic between conventional analog telephones and packet-based data networks, such as commercial IP networks or the Internet. Catapult's support of this standard is very significant to the VoIP industry. In SS7, Catapult adds support for INAP and TUP (Telephone User Part) See SS7. and enhancements to TCAP. These protocols make international calls and the classic features like call waiting and toll free numbers possible. The DCT2000 has also added a new graphical utility to make SS7 MTP routing tables more user friendly and to speed development. "Our customers are developing leading edge products and require state-of-the-art testing capabilities for the latest protocols," stated Dave Mayfield, Catapult president and COO. He continued, "This software release further strengthens Catapult's position as a major supplier of 3G and VoIP test systems for these rapidly growing markets."
