PCSI Unveils Family of pACT Data Base Stations for Paging Service Providers; pACT Allows Carriers to Offer Low-cost, Advanced Two-Way Messaging and Paging Services.SAN DIEGO--(BUSINESS WIRE)--March 25, 1996--PCSI, a wholly owned subsidiary Wholly Owned Subsidiary A subsidiary whose parent company owns 100% of its common stock. Notes: In other words, the parent company owns the company outright and there are no minority owners. of Cirrus Logic Inc. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :CRUS), unveiled its family of pACT Data Base Stations (PDBS PDBS Polarization Dependent Beam Splitter PDBS Precedence Dialing Behind the Switch PDBS Position-Dependent Band Structure ) for providers of messaging and paging services. pACT (personal Air Communications Technology) is a new wireless two-way messaging and paging technology co-developed by PCSI PCSI Pacific Communication Sciences, Inc. PCSI Patient Classification Systems International PCSI Pakistan Cotton Standard Institute PCSI Perfect Channel State Information PCSI Polymer Coatings and Surfacings Institute for providing advanced wireless messaging services for narrowband personal communications services See PCS. (NPCS NPCS Northern Potter Children's School NPCS Narrowband Personal Communication System NPCS Non-Preemptible Critical Section Algorithm ). The PDBS transmits data between messaging devices (also called pACT end system or "PES pes (pes) pl. pe´des [L.] 1. foot. 2. any footlike part. pes n. pl. pe·des 1. The foot. 2. " devices) and the pACT Data Intermediate System (PDIS PDIS Parallel and Distributed Information Systems PDIS Plant Diagnostic Information System (National Plant Diagnostic Network) PDIS Preparation for Dissemination PDIS Procurement Document Imaging System ) installed at the service providers sites. Modularity, Flexibility, and Reliability PCSI's family of PDBS products includes a wide variety of high performance base stations that offer superior, cost-effective data communications capabilities to paging networks. The base stations can be tailored to paging network requirements with flexible and versatile configurations based on modular designs, redundancy, extended performance, power management and external shelter requirements. This modular approach enables service providers to increase channel capacity and redundancy as desired. Currently, two power amplifier options are available in standard 50 watt and 150 watt PDBS versions. Performance PCSI's proven RF expertise in Cellular Digital Packet Data (communications, protocol) Cellular Digital Packet Data - (CDPD) A wireless standard providing two-way, 19.2 kbps packet data transmission over exisiting cellular telephone channels. (CDPD (Cellular Digital Packet Data) A low-speed, digital, wireless data network that is an enhancement to an existing analog cellular network. Based on IBM's CelluPlan II, CDPD provides a packet overlay onto the AMPS network and moves data at 19. ) has been applied to the PDBS products. The base stations utilize a technique called "four branch maximal ratio coherent combining diversity" which improves receiver performance and sensitivity to moving PES devices compared to non-diversity designs. Static sensitivity performance of PCSI's PDBS products exceed the requirements of traditional AMPS cellular voice base stations. This results in each PDBS supporting coverage areas two to four times that of AMPS base stations. Additionally, each PDBS has been designed to minimize emissions in the AMPS receive band, as well as other receive bands. Antenna isolation allows for signals in numerous frequency bands to be transmitted simultaneously without interference. Network Management PCSI's family of PDBS products include an industry standard network management system for network configuration and control of pACT network and equipment parameters. Nearly all configurations can be made dynamically and management features include alarm reports, event logs, and service and equipment performance statistics. About pACT pACT offers the speed, security, capacity and flexibility demanded by the messaging and paging requirements of the market today. The pACT open protocol provides significant benefits to both paging service providers and end users. Benefits to service providers include interface flexibility, greater network capacity using cellular-like frequency re-use, encryption for security, operational flexibility and network expansion options. pACT end users benefit from low-cost PES devices, long battery life, ubiquitous coverage, superior in-building penetration and guaranteed message delivery. Other benefits come from the variety of two-way messaging and paging applications supported by pACT such as location services, message origination, telemetry and high throughput capabilities for data, email, voice mail and fax. In October of last year, PCSI received a multimillion dollar contract from AT&T Wireless Services Inc. for its PDBS products. Field trials, which began earlier this year, are being jointly conducted by AT&T and PCSI and are expected to continue through September. In addition to infrastructure equipment, PCSI is developing chip sets and system test and deployment tools to support pACT. PCSI is a leading supplier of products and technology for advanced wireless communications and telecommunications systems around the world. PCSI's portfolio of products include infrastructure and end-user products, as well as highly integrated chip sets and OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and modules. PCSI recently announced it first PAL (Personal Access Link) phone which integrates cellular voice, circuit-switched and CDPD wireless data, and two-way messaging capabilities into a single handset. The company holds the ISO (1) See ISO speed. (2) (International Organization for Standardization, Geneva, Switzerland, www.iso.ch) An organization that sets international standards, founded in 1946. The U.S. member body is ANSI. 9001 Quality System Certification. Headquartered in Fremont, Calif., Cirrus Logic is a leading manufacturer of advanced integrated circuits for the desktop and portable computing, telecommunications, and consumer electronics markets.
