Architecture of a New Inhouse Communication System Providing Integrated Circuit and Packet Switching
A new inhouse communication system is suggested, integrating circuit switched services with variable bandwidth and packet switched services with variable throughput rate. The concept is based on the existing subscriber lines for ISDN services, and extended by small LANs and new PBXes, which are interconnected through broad-band links. LANs, PBXes and broad-band links are appropriate for integrated circuit switching and packet switching. In the first part of this paper, integration principles within the PBX as well as implementation aspects are outlined. The second part compares performance results of several strategies to achieve the integration of both switching principles on a ring system and presents a pilot implementation.
