New point-to-multi-point microwave access system introduced to US market at SUPERCOMM '96.RICHARDSON, Texas--(BUSINESS WIRE)--June 26, 1996--Ericsson today introduced ACTRAN ACTRAN Acoustic Transmission ACTRAN Analog Computer Translator , a new point-to-multi-point microwave access system, to the US market at SUPERCOMM '96. This new Radio in the Local Loop (RLL (Run Length Limited) An encoding method commonly used on magnetic disks, including RLL, IDE, SCSI, ESDI, SMD and IPI interfaces. The actual number of bits recorded on the disk is greater than the data bits. ) access system will allow operators to quickly deploy integrated, mixed service communications supporting POTS, CENTREX, ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. and 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). connections as well as video and data services. In a suburb of London, business customers are already bypassing the local loop using ACTRAN. The system is built upon a modular cellular architecture with a central nodal Having to do with nodes. See node. NODAL - Interpreted language implemented on Norsk Data's NORD-10 computers. Used by CERN and DESY high energy physics labs to control their accelerator hardware, PADAC and SEDAC. Included trackball input, graphics. site that is sectorized from 15-90 degrees in order to increase either propagation or capacity. Each site can be sectorized according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. the needs of that particular area. The flexibility and modularity of the system allows the operator to maximize the utilization of the two most important commodities: money and frequency. ACTRAN offers a wide range of features including high bandwidth which is efficiently utilized through dynamic bandwidth allocation Dynamic Bandwidth Allocation (DBA) is a technique by which traffic bandwidth in a shared telecommunications medium can be allocated on demand and fairly between different users of that bandwidth. using the frequencies only as they are required by the system. This allows the system to provide up to 10,000 or more 64 kbps subscriber channels per radio cell. Channels are dynamically assigned to subscribers as required. ACTRAN can be quickly and easily deployed in metropolitan areas bringing advanced high capacity services to the business market. The system uses standard interfaces to the exchange and with its modular cellular structure, offers a grow-as-you-go approach to new or existing operators. Reliability in the system is as good as, if not better than, copper. Security is ensured through the use of variable data rate fully digital modems with advanced digital modulation and coding techniques. For added security, an encryption and authentication system can be added. A stand-alone Network Management System controls every element of this transmission system. Ericsson's 85,000 employees are active in more than 100 countries. Their combined expertise in switching, radio and networking makes Ericsson a world leader in telecommunications.
