COMCOR Selects ADC's ATM Access Concentrators to Maximize the Delivery of High-Speed Services.Business Editors MINNEAPOLIS--(BUSINESS WIRE)--Feb. 21, 2000 ADC (1) See A/D converter. (2) (Apple Display Connector) A peripheral connector from Apple that combines digital video display, USB and power in one cable. (Nasdaq:ADCT ADCT Adaptive Discrete Cosine Transform ; www.adc.com) today announced that COMCOR, a Russian communications carrier, has chosen ADC's ATM Access Concentrator See remote access concentrator. (AAC-3) to enable frame relay A high-speed packet switching protocol used in wide area networks (WANs). Providing a granular service of up to DS3 speed (45 Mbps), it has become popular for LAN to LAN connections across remote distances, and services are offered by most major carriers. over an ATM network for delivery of permanent virtual circuit See PVC. (networking) Permanent Virtual Circuit - (PVC, or in ATM terminology, "Permanent Virtual Connection") A virtual circuit that is permanently established, saving the time associated with circuit establishment and tear-down. (PVC PVC: see polyvinyl chloride. PVC in full polyvinyl chloride Synthetic resin, an organic polymer made by treating vinyl chloride monomers with a peroxide. ) services to businesses in Moscow. The purchase, which includes the deployment of a 24-node network, was facilitated by ADC's Russian distributor Falcon-S. "With the AAC-3 we can now accelerate the delivery of PVC services to local government groups such as medical, police and fire departments," said Vladimir Bulanov, deputy general director, COMCOR. "The AAC-3 clearly provides an economical delivery for the high speed services these agencies demand." Prior to the selection of the AAC-3, COMCOR offered a trial frame relay service directly from ATM switches. This application was found to be inefficient and costly. The AAC-3, with much more cost-effective concentration of ATM services will enable the carrier to provide high performance frame relay service delivery and realize a quick return on their network investment. The AAC-3 can be configured to support data, voice and video through traffic shaping and inverse multiplexing over ATM (IMA (Interactive Multimedia Association, Annapolis, MD) An earlier trade association founded in 1988 originally as the Interactive Video Industry Association. It provided an open process for adopting existing technologies and was involved in subjects such as networked services, scripting ) capabilities with high density El circuit emulation service (CES) interfaces. IMA network interfaces include frame relay interworking (standard) interworking - Systems or components, possibly from different origins, working together to perform some task. Interworking depends crucially on standards to define the interfaces between the components. , V.35/X.21, HSSI (High-Speed Serial Interface) A serial interface with transmission rates up to 52 Mbps. It is often used to connect one or more LAN routers and network devices to a T3 line, which provides 44.736 Mbps. , OC-3 and T1/E1. The AAC-3 is also easily upgraded to faster services by simply changing physical interfaces, protecting the initial equipment investment as network requirements change. "Global carriers are using ADC's ATM Access Concentrators for new NxTl/El IMA services, fueled by ATM customers interested in high-speed frame relay and ATM between El and E3 services," said Joe Mocerino, international program manager in ADC's Broadband Access and Transport Group. "The world-class traffic shaping module for the AAC-3 enables users to maximize their WAN efficiency, while helping carriers ensure conformance with service level agreements."
