    摘要： A telecommunication system including a rotary dial subscriber set for transmitting sequences of dial pulses to a telephone central office over at least two conductors is disclosed. In response to a first set of dialed digits, the central office establishes a DC conductive path between the subscriber set and a DC blocking trunk circuit. A central office scan arrangement is connected to the communication path to determine the conduction state between the conductors of the communication path in order to maintain or remove the communication path. The system also includes a dial pulse detector which detects and counts dial pulses in each sequence of dial pulses transmitted from the subscriber set. In response to the first dial pulse of each sequence, the dial pulse detector generates signals which are utilized to inhibit the central office scanner from detecting further dial pulses. After each dial pulse sequence and before a subsequent one can occur, a tone generator transmits an AC coded signal on the communication path representing the number of dial pulses counted by the dial pulse detecting arrangement.

    摘要： The system of the invention has particular application to a wide area network (WAN) where call routing information often changes in one local area network (LAN) (e.g. a switching system) while other LANs (e.g. cellular communication systems) are unaware of the changes. Because of the heavy flow of traffic in such networks, the minimization of administrative traffic data is desirable. The invention solves the need for constant updating and auditing of the LANs in the WAN. One LAN is considered the master LAN for a given parameter and contains an accurate directory of administrative data for that parameter. Each of the other LANs operate on the assumption that the administrative or directory information it contains is correct. If this assumption is wrong for a particular parameter and a LAN contains incorrect information, in response to a communication to or from the LAN, the system: 1) recognizes that the information relating to the parameter is incorrect; 2) determines the correct information and completes the communication based upon the correct information; and 3) updates the LAN with the correct information from the master LAN such that the next time the same communication is attempted the LAN has the correct information. In this manner, the LANs are updated on a need to know basis only after an actual communication is attempted thereby eliminating the constant transmission of administrative information between the LANs that exists in the prior art systems.

    摘要： A distributed control switching system where the system control units cooperatively perform the terminating port determination function. The control unit associated with the terminating port stores sequence call data defining whether calls are to be completed to that terminating port or are to be forwarded to another directory number. Upon determining that a given call is a sequence call, the control unit associated with the original terminating port determines the terminating port defined by the second directory number and effects a reduction of the sequence call to a simple call between the originating port and the second terminating port. This is done either by transmitting a control message defining the originating and terminating ports to the control unit associated with the second terminating port or by returning the setup sequence to the control unit associated with the originating port which then frees any switching system resources previously allocated to the call and transmits the control message. In either case, the control unit associated with the second terminating port completes the call without knowing whether the call is a sequence call or a simple call completed to the original terminating port.

    摘要： A distributed control switching system where multi-port hunt groups are controlled by hunting for idle group members in a sequential fashion starting with the members on one of the switching modules of the system and continuing through a predetermined sequence of modules until an idle group member is found. The busy/idle hunt data is distributed across the modules so that each module maintains the hunt data for only the group members on that module. Therefore, no inter-module control communication is devoted to updating the hunt data of other modules.
