摘要： A variable-band distributed switching node comprises a plurality of independent modules (MU.sub.1 . . . MGm) inserted between subscriber or trunk lines and a common bus (1). Each module includes an input/output portion (IU, HL, SL, PL), processing line information, and an interface (IB) toward the bus which co-operates with the interfaces of the other modules to form hybrid frames on the bus. These frames are each divided into a first region RC, encompassing a plurality of channels assigned to circuit-switched communications, and a residual-band second portion RP shared by packet-switched communications. Such frames are dynamically managed by assigning to each circuit-switched channel a band which can differ in consecutive frames to satisfy the requirements of variable-band sources and by recompacting the channels remaining in region RC after each channel release.

摘要： A communication system serving a number of nodes, each associated with a group of subscriber terminals, comprises a unidirectional bus bent into a loop to form a transmitting branch and a receiving branch respectively connected by an outgoing coupler and an incoming coupler to all the terminals of a given node. In each node a plurality of detectors on opposite sides of the outgoing coupler monitor the activity of the transmitting branch to determine whether the bus is free from any signal carrier originating at an upstream node, or generated at the node considered, and is thus available for voice or data packets to be sent out. Each terminal includes a receiving unit, responsive to a pre-engagement packet addressed thereto via the incoming coupler, which starts a local time base to establish a succession of frames encompassing each a number of time slots allocated to active speech channels in a voice period of a frame; the remainder of each frame is available for data transmission. The number of time slots constituting the voice period is variable; a memory forming part of a control section including the time base stores information on the state of activity of each time slot.

摘要： Each of several stations served by a common bus in a communication system of the packet-switching type has a layered structure interposed between a user terminal and a port giving access to the bus, this structure including an interface separating a transceiver at a bottom level of the structure from upper levels controlling the establishment, maintenance and termination of temporary signal paths for the transmission of data between stations. The interface is divided into a lower-tier portion, implemented by wired-logic circuitry, and a higher-tier portion, programmed to set up virtual point-to-point data links between its own station and other stations under the control of a microprocessor. The lower-tier portion dialogues with the transceiver and has transmitting and receiving sections with respective buffer memories for the temporary storage of outgoing message frames generated at the higher-tier portion and incoming message frames extracted from the bus and found to be addressed to the station involved. When an outgoing sequence consisting of one or more frames has been completely stored, or when the transmitting-side buffer memory is full, a logic unit in the transmitting section explores the probability of successful access to the bus with the aid of an algorithm based on a random numerical sequence different for several stations competing for access. When such access has been gained, the stored sequence is sent out. When an incoming sequence has been completely received, or when the receiving-side buffer memory is full, the contents of that memory are transferred to the higher-tier portion.
