The purpose of development is working up the design documentation and the software and introduction into manufacturing of the subscriber concentrator for Integrated Services Digital Networks (ISDN) with the purpose of provision of a wide range of services, including intelligent services, high-speed data transfer and access to INTERNET. The maximum subscriber concentrator capacity makes 1920 analogue subscribers or 960 digital ISDN base access subscribers (2В+D). The maximum number of connecting lines (CL) - 480. The general safe load for the concentrator is up to 960 erlang. The minimum build-up discrete value is determined by the subscriber access module capacity and is 32 for analogue access subscribers and 16 for ISDN base access subscribers (2В+D). The minimum build-up discrete value of the concentrator connecting line is 120. The results of the (experimental) development are introduced into manufacturing. Future suggestions: further development of the subscriber concentrator into the office and production ATE with ISDN functions. Product Description popup.authors popup.nrat_date 2020-04-02 Close
