摘要： Sensors SE and drivers AT electrically linked to various points of communication equipment, e.g. in a telephone system, are periodically explored by an interface linking them with a processor, under the control of a time base successively reading out their addresses during synchronous phases of respective time slots of a recurrent frame also having other phases set aside for the asynchronous exchange of data with the processor. The interface comprises a first and a second read/write memory ME.sub.1, ME.sub.2 respectively storing information relating to the evaluation of incoming signals from the sensors and to the sending of outgoing signals to the drivers, the contents of these memories being updated from time to time during asynchronous phases allocated to communication with the processor. The evaluation of incoming signals is performed in a first logic network IN, with the aid of integrating circuitry including a read-only memory ROM.sub.1 inserted in a feedback loop of the incoming-signal memory ME.sub.1 ; the forwarding of change-of-state signals from this logic network IN to the processor may be inhibited in selected instances by masking criteria stored in the incoming-signal memory ME.sub.1 which can be modified, on instructions received from the processor, with the aid of a second logic network LM including another read-only memory ROM.sub.3 also inserted in a feedback loop of memory ME.sub.1.

摘要： A hybrid routing technique for an analog or digital switching communication network containing several switching centers for contacting a called subscriber at a destination switching center whose location in the network need not be known to the calling subscriber and for providing a deterministic route back from the destination switching center to the originating switching center. The entire system is substantially simultaneously flooded once in parallel radial fashion with a flood signal of simple format containing information representing the calling switching center, the called subscriber and the time or origination of the call; local subscriber directories at each of the switching centers of the network are examined substantially simultaneously to determine which of the switching centers is the destination switching center. The selection of a route between the called and the calling subscribers is done independently of the locating of the called subscriber and allows effective selection of routes, based on an abundance of information available at the switching centers concerning the current status of the network and regardless of transmission delays along the routes.

摘要： A plurality of idle paths through a multistage switching network which are capable of establishing a connection between a particular line and a particular trunk are identified. Repeated selection of paths identified as idle, but actually out-of-service, is avoided by selecting successively different ones of the identified idle paths in a pseudorandom manner to complete the connection between the line and the trunk. The pseudorandom path selection is accomplished in response to predetermined portions of a pseudorandom pattern of binary bits.

摘要： A multilink nodal switching network is disclosed which permits heavy traffic among a plurality of equi-interconnectible switching nodes. Circuitry for busy-testing, for marking idle links and for steering crosspoint operating potential to a selected idle link in a designated direction is shown. The multilink nodal network is a higher traffic carrying version of the single link nodal switching network of my prior patent application Ser. No. 393,595 filed Aug. 31, 1973. A link marking potential is applied at the given node to which the connection has reached, a next node in the direction of the called node is ascertained and a group of its links lying in the direction of the given node are busy tested. A crosspoint operating potential is steered to a first idle one of the tested links at the next node and, in cooperation with the marking potential, operates a crosspoint at the given node. After the crosspoint operates at the given node the link marking potential replaces the crosspoint operating potential at the next node.
