CTP Systems Announces New 1.9 GHz Wireless Adjunct PBX System; CTPhone Integrates Wireless Into PBX Systems to Provide In-Building Mobile Communications and Advanced Telephone Features.CUPERTINO, Calif.--(BUSINESS WIRE)--Feb. 12, 1996--CTP Systems, a subsidiary of DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive Communications (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities.

See communications. solutions for in-building mobile communications, today unveiled CTPhone, a wireless PBX (Private Branch eXchange) An inhouse telephone switching system that interconnects telephone extensions to each other as well as to the outside telephone network (PSTN). system that allows employees to use a portable handset as a fully-featured wireless extension to their desktop telephone. When integrated into an organization's PBX, CTPhone provides employees with the freedom and convenience of a mobile phone around the workplace, while allowing them to keep the same extension number and features of their desktop handsets. The CTPhone system includes handsets, base stations and a control interface card to manage the switching within any PBX configured to work with the system. It operates in the portion of the new 1.9 GHz frequency band reserved for unlicensed personal communications services Unlicensed Personal Communications Services or "UPCS" describes the 1920-1930 MHz frequency band allocated by the FCC for short range applications in the United States, such as the Digital Enhanced Cordless Telecommunications wireless protocol. (PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. ).

"CTP's new wireless PBX system is the first of its kind to enable corporations to add wireless capability to their phone system," said Rony Greenberg, vice president of Marketing for CTP. "CTPhone's ease of integration with nearly any analog or digital PBX (digital Private Branch Exchange) A modern PBX that uses digital methods for switching in contrast to older PBXs that use analog methods. , will help bring the benefits of mobile communications in the workplace to millions of workers in the manufacturing, service and retail sectors." The System CTPhone can be integrated into any analog or digital telephone switching Telephone switching Moving one's assets from one mutual fund or variable annuity to another by telephone. telephone switching The movement of an investor's funds from one mutual fund to another mutual fund on the basis of an order given via system, including PBX, Centrex or key systems. It features a microcell system architecture which subdivides the coverage area into pico cells, each served by a base station. Because base stations are only 3" deep and approximately one foot square, they can be mounted unobtrusively on a wall or ceiling. Base stations can be connected up to 6,000 feet from the PBX by twisted pair A thin-diameter wire (22 to 26 gauge) commonly used for telephone and network cabling. The wires are twisted around each other to minimize interference from other twisted pairs in the cable (Alexander Graham Bell invented this and was awarded a patent for it in 1881). wiring, and can be powered from the PBX or by local power. Each base station can serve simultaneously up to eight full-duplex conversations, and each CTPhone system can accommodate up to 32 base stations. Therefore, a single system can support up to 256 simultaneous conversations, and serve up to 1,536 users by implementing over-the-air assignment. A base station's range is 300 feet in a typical office environment, and 3,000 feet in open space, with a total system coverage area of up to five million square feet. A typical office environment configuration consists of up to 1,536 handsets and 32 base stations, each with a coverage area of approximately 320,000 square feet. The handsets are lightweight (7 oz.), compact and have very low power consumption, enabling four hours of talk time and 40 hours of standby time. They give users all the features of their conventional desktop telephones, including auto answer, paging alert, speed dialing, call waiting, message waiting, displayed message, call pick up and more. Handsets include a scrolling LCD that displays the name and extension of the calling party. They also display system function icons that alert users to voice mail, e-mail, pages, ringer volume, signal strength and battery life. Each handset comes with an AC-powered cradle for recharging.
