<p>Two new units of the system, the Digital Interconnection Unit and the Local Area Network Gateway Unit are described. The Digital Interconnection Unit allows the connection of a base ring to another base ring, or the connection of several base rings to another ring serving as an interconnecting ring, or the connection of a base ring or of an interconection ring to a digital link. It consists of the Base Nucleus (common for all units) and four additional modules: the multiple access electronic memory module (11); the modulation/demodulation module (12); the information control and processing module (13); and the coding, interface and adaptation module (14). The Local Area Network Gateway Unit allows the connection of a local area network (LAN) to a base ring. It consist of the Base Nucleus (common for all units) and four additional modules: the highway bus coupling module (31); the buffer module (32); the Local Area Network Gateway Unit control module (33); and the local area network coupling module (34).</p> |
