A telephone network management operating system and a network manager determines that a toll switch is sufficiently inoperative and invokes a trunk group reconfiguration mechanism. A cross connect system, such as a DCS (Digital Cross-connect System), links the toll-completing trunk groups coming into such an inoperative toll switch to intertoll trunk groups coming into such a toll switch. In this manner, an alternative toll switch within the telephone network replaces the inoperative toll switch for such toll-completing trunk groups thereby restoring operation to customers previously tied to the inoperative toll switch in an efficient and low-cost manner by using already existing components within the telephone network.

  • Patent number: 5956396
    Abstract: Local/toll dynamic routing integration is achieved within a telecommunications network (14) that includes at least one dynamic routing local switching system (24-1) for receiving incoming call and a plurality of toll switching systems (27-1 through 27-7) at least one of which is associated with each local switching system. For each incoming call, the local switching system (24-1) derives a set of Class-Of-Service (COS) parameters indicative of the class-of service associated with the call. In accordance with the COS parameters, the local switching system (24-1) determines whether each incoming call is a featured call, requiring routing to the toll switching system associated therewith, or a non-featured call. Featured calls are routed to the toll switching system associated with the local switching system for feature processing, whereas non-featured calls are routed by the local switching system itself in accordance with the COS parameters, thus relieving the load on the associated toll switching system.

  • Patent number: 5940491
    Abstract: Apparatus and method for controlling establishment of telecommunications call connections in a telecommunications network. The network comprises a plurality of switches each with its own switching processor means, and a plurality of switching processing platforms each comprising at least one call processor. The switches and switching processing platforms are interconnected by a data network. SS7 signaling messages are received in one of the platforms and a call is assigned to a call processor. The call processor communicates with one or more switching processor means for controlling establishment of the call. Call features are processed under the control of the call processor. Advantageously, any call processor can be used for serving any call in the network and can control all legs of a multi-leg connection. Advantageously, in a large network, the number of platforms may be significantly less than the number of switches which reduces the cost and complexity of administration of the network.

  • Patent number: 5844981
    Abstract: A method and system of improved routing to WATS completes calls through a wide area telephone service using indirect routing. When a call is placed from a calling telephone station to a called telephone station, a telephone network attempts to route the call from the originating switch, on which the call entered the network, to a local exchange carrier serving the called station. If other routing paths in the network are unavailable or unsuccessful, a network processor recommends a routing from the originating switch to the local exchange carrier through a tandem switch and the WATS line of another telephone network. This capability provides a reduced incidence of blocked calls, such as may result from telecommunications system outages.

  • Patent number: 5815559
    Abstract: In an automatic message accounting (AMA) record distribution network, a method and system for sorting AMA records by using an area code or numbering plan area (NPA) data array and directory number bit maps to identify AMA records which are of interest to an operation center. Operation centers have access to every AMA record generated by a toll switching network and are initialized with a table of AMA structure and call-type codes, an NPA data array and directory number bit maps. NPA entries in the data array which are of interest to a particular operation center contain pointers (i.e., memory address locations) of the directory number bit maps. As AMA records are received by the operation center, directory numbers which have NPAs of interest to the operation center are compared to directory number bit maps. A directory number of an AMA record which corresponds to a numbered bit position of the directory number bit map is processed by the operation center.

  • Patent number: 5787150
    Abstract: Method and apparatus allow a caller to contact a called party with a collect call whether or not the called station is answered or is busy. When the caller dials a collect call access code, the call is routed to a messaging platform which collects the call information and attempts to complete the call. If there is no answer or if the called station is busy, the messaging platform retains control of the call and automatically prompts the caller to enter a name and a message to be delivered to the called party. After the name and message have been entered, the caller is given a confirmation number, if desired, which allows the caller to determine whether the called party has received the message. The messaging platform repeatedly attempts to deliver the message by calling the called party. Upon the call being answered, the messaging platform identifies the caller and prompts the called party to accept or refuse the collect message.

  • Patent number: 5539817
    Abstract: A method of providing multi-switch business group (MBG) services at each of a plurality of locations is described. The MBG services can be provided for calls made from a calling party served by an originating switch at one location to a called party served by a terminating switch at a location serviced by an inter-exchange carrier (IEC). When the calling party goes off-hook, a determination is made of whether the call is made from a centrex line. Digits dialed by the calling party are then collected at the originating switch. A determination is then made of whether the dialed digits contain an access code indicative that the call is to be routed to one of the plurality of locations which is served by an IEC. If the call is to be routed via an IEC, the initial address message (IAM) required for IEC calls, is modified to include MBG service information. This will permit MBG services to be offered between the calling party and the called party over public CCS7 trunks routed via an IEC.

  • Patent number: 5533111
    Abstract: Access (or egress) charges payable by an IXC to a LEC, and payable by the subscriber to the LEC for originating or terminating calls and for associated vertical call control features, are reduced or eliminated by providing a virtual piped collection that "bypasses" and thus does not require the involvement of, a local service provider. The virtual piped connection exists between a call control platform (CCP) in the IXC network, and specialized customer premises equipment (CPE) located m the subscriber location. The specialized CPE is arranged to provide call control functions using normal out-of-band signaling in a conventional manner, and, after an initial call is conventionally set up to the CCP, to provide the same functions using specialized in-band signaling. A complementary signaling and control capability is provided in the CCP.
