Abstract: A subscriber communication system which includes a base station 104 in a network with a number of subscriber stations 41 where control information is sent between the base station and the subscriber stations over a radio control channel RCC with a frequency which is selected by the base station 104 from a number of predetermined frequencies. The base station 104 transmits control messages, which include a unique network number, over the radio control channel. Each subscriber station 41 processes the network number in the control message received over the radio control channel to enable the subscriber station to process the control message in accordance with whether the subscriber station 41 is located in the same network as the base station 104. The time matching of messages which are sent by a subscriber station 41 over a given connection channel between a base station 104 and the subscriber station is improved after the initial setting up of the connection channel. Both DC signalling information and sound data signals are sent over an allocated channel between a virtual line, which connects a base station to an exchange, and a line interface which connects a subscriber station 41 to a subscriber terminal 115, 116.

Abstract: The subscriber communication system includes a base station in a network with a number of subscriber stations, where control information is communicated between the base station and the subscriber stations over a radio control channel (RCC) at a frequency selected by the base station from a number of predetermined frequencies. The a base station transmits control messages including a unique network number over the RCC. Each subscriber station processes the network number in the control message received over the RCC to enable the subscriber station to process the control message in accordance with whether the subscriber station is in the same network as the base station. The timing of communications transmitted by a subscriber station over a given communication channel between a base station and the subscriber station is refined upon initial establishment of the communication channel.

Abstract: Base station in communication with telephone lines for the simultaneous wireless transmission of information signals to a number of subscriber stations between the base station and each of the number of subscriber stations. The base station comprises a first interface which is connected via trunk lines to the telephone lines; signal compression means which are connected to the aforementioned first interface by means of a number of trunk lines for the simultaneous compression of different digital signal patterns in order to provide different compressed signals and channel-control means which are connected to the signal compression means for the sequential combination of the compressed signals into a single transmission bit stream, each of the respective compressed signals occupying a respective sequential position in the transmission bit stream. Furthermore, transmission and reception means are provided in the base station to establish direct wireless communication between the base station and the number of subscriber stations.

Abstract: The base station includes a communication circuit for enabling simultaneous communications between a number of ports and a number of the subscriber stations over a given communication channel having multiple sequentially repetitive time slots. An exchange is included to connect the communication circuit to the external communication network ports. A remote-connection process is coupled to the communication circuit by the exchange and by a base-station control channel occupying a selected one of the time slots for monitoring the status of the other time slots. The connection processor causes the communication circuit and the exchange to complete a connection between a given communication network port and a given subscriber station over a time slot assigned in response to the monitored status in accordance with a predetermined assignment routine.
