ABSTRACT:
A base station in a subscriber communication network for communicating signals between subscriber stations and an external communication network having a plurality of ports. The base station includes a communication circuit for enabling simultaneous communications between a plurality of the ports and a plurality of subscriber stations over a given communication channel having multiple sequentially repetitive time slots; a remote-connection processor for directing communications between the time slot assigned to a given subscriber station and a given external communication network port; and an exchange for connecting the communication circuit to the external communication network ports. The exchange includes a central concentrator for directing signals from predetermined external network ports to predetermined sequentially repetitive time slots in a bit stream generated by the central concentrator, and for directing signals to predetermined external network ports from predetermined sequentially repetitive time slots in a bit stream received by the central concentrator; and the remote-connection processor directs signal transfer between given sequentially repetitive time slots of the bit streams and given sequentially repetitive time slots of the communication channel. The remote-connection processor includes a remote concentrator for directing signals from predetermined remote ports to predetermined sequentially repetitive time slots in a bit stream generated by the remote concentrator and transmitted to the central concentrator, and for directing signals to predetermined remote ports from predetermined sequentially repetitive time slots in the bit stream generated by the central concentrator.
