TELECOMMUNICATIONS INDUSTRY GROUP VOTES TO WORK TOWARD STANDARDIZATION OF INTERFACE FOR CELLULAR NETWORKS

 ARLINGTON HEIGHTS, Ill., Oct. 13 /PRNewswire/ -- Motorola announced today that the TR 45.4 subcommittee, sponsored by the Telecommunications Industry Association, has voted 11 to three to establish a new working group for the standardization of an open and common cellular interface.
 Under consideration by the subcommittee will be the standardization of an open "A minus interface," using North American standards, to connect base station subsystems and mobile telephone switching offices.
 Last July, Motorola proposed an A plus interface. It has since gained support from 20 telecommunication service providers and equipment vendors including Qualcomm and Siemens corporations, which announced their support for A plus this month.
 A plus is similar to the interface adopted as a standard for the European GSM (Global System for Mobile Communications) network and already is deployed by a number of the world's leading switch and cell site vendors.
 When approved, the A plus open interface would enable cellular operators to deploy systems comprised of equipment from competing vendors. The proposed standard specifies how a cellular system can manage digital and analog voice traffic between cell site equipment and any switch.
 Historically, increased competition has translated into more affordable cellular service, the rapid introduction of new services and cellular market growth.
 "Among the benefits of a standardized interface are lower costs and greater system flexibility for cellular operators," said Marty Singer, vice president, business development and planning, Motorola Cellular Infrastructure Group. "The goal is to have all vendors competing on the basis of price, performance and quality, instead of protecting their turf with proprietary restrictions."
 Motorola is one of the world's leading providers of wireless communications and electronic equipment systems, components and services for worldwide markets. Products include cellular telephones and systems, two-way radios, pagers, personal communication systems, semiconductors, defense and aerospace electronics, automotive and industrial electronics, computers, data communications and information processing and handling equipment. Sales in 1992 were $13.3 billion.
