  • Patent number: 7376224
    Abstract: A system and method are provided for enabling additional capacity or features on telecommunication nodes without requiring replacement of hardware. Service providers purchase hardware which is fully capable of providing a full suite of features and providing a large bandwidth capacity. However, depending on the amount of payment by the service provider, not all of the features or the bandwidth capacity is enabled. If the service provider wishes to increase the number of features or the capacity of a node, the additional features or capacity are enabled using software after payment to the vendor. This allows service providers to enter the market at an initially relatively low expense. Additional features and capacity can be purchased and enabled using software as demand grows, without having to purchase replacement hardware.

  • Patent number: 5781624
    Abstract: A method of operating a network by sharing resources associated with various classes among calls in the various classes according to a state dependent reservation parameter. Nominal amounts of one or more resources are allocated to each call class. When a call of a class of service operating in the network requires resources in excess of those allocated to the class, resources allocated to other classes of service are advantageously shared with the class of service. The sharing is based on a reservation parameter associated with the class of service of the call. The reservation parameter is advantageously a function of the network state. The role of the reservation parameter is to protect underloaded classes (i.e., those classes not using all of their allocated nominal capacity) from excessive borrowing by overloaded classes (i.e., classes using more than their allocated nominal capacity).

  • Patent number: 5442689
    Abstract: In a method implemented by a telecommunications switch, a call request is made for a called party having a predetermined directory number. A determination is made if preconnection services are to be provided for the called party, and if such services are to be provided, a service node to provide the services is identified. A further determination is made if the call request is from other than the selected service node. If the call request is not from the selected service node, the call request is routed to the service node for preconnection services. If a call request is from the selected service node, the call is routed to the called party. This permits a selected service node to originate a separate call to the called party so that services can be provided on behalf of the called party in response to a call request made by a calling party. This method allows preconnection services to be provided without the requirement of multiple directory numbers being assigned to the called party.

    Abstract: This invention relates to apparatus and a method for controlling a Digital Access and Crossconnect System (DACS) from a connected toll switching system. All control messages from operations support systems (OSS) for making crossconnect changes in the DACS are first routed to the toll switch. The toll switch extracts information needed to update its database and sends a control message to the DACS. In addition, the toll switch responds to changes in traffic patterns, perhaps due to the loss of a transmission facility, to generate a crossconnect change message to the DACS to rearrange facilities for more optimum performance. Advantageously, the OSSs for DACS control and switch control is combined and the toll network is made more responsive to traffic pattern changes and to losses of transmission facilities.

  • Patent number: 5033076
    Abstract: This invention relates to apparatus and a method for use in conjunction with a service wherein a called telephone customer receives a display of the number of a calling telephone customer. In conjunction with this service, customers are offered a class of service and/or an option to dial a privacy request wherein their telephone number will not be displayed to the called telephone customer. In accordance with this invention, the customers are offered a class of service wherein they will receive calls only from telephone customers willing to have their telephone number displayed. If a call is made from a caller who does not wish to have his number displayed to a called customer who will not accept calls from customers unwilling to identify themselves, the caller is given a special announcement; in response to this announcement if the caller keys a special privacy override code then the call is completed with the caller's number displayed.

  • Patent number: 5017917
    Abstract: Subscribers (100-108) of an electronic mail system (1-2) service are divided into a plurality of subscriber communities (30-34). Subscribers in each community have common rights of access to one or more communication service--the sending and receiving of mail messages--which rights are generally different from those of subscribers in other communities. Permissions to send and receive messages between any two communities are specified on each mail system in a permissions matrix (40), wherein each row (41) represents a different sender community, each column (42) represents a different recipient community, and the value stored at their intersection (43) indicates the permission vis-a-vis the two communities. A function (50) is invoked on the sender's mail system (1,2) at message addressing, and on the sender's and recipients' mail systems (1,2) at message delivery, to enable or prevent (FIG. 3) message sending or delivery according to the matrix-specified permissions.

  • Patent number: 4799255
    Abstract: The communication facilities access control arrangement of the telephone munication system detects the dialing of an unauthorized or invalid long distance transmission facility access code and identifies the calling station. A record is maintained of all invalid attempts to access the long distance facilities. When the number of invalid attempts by a calling station exceeds a predetermined limit, the telephone communication system restricts the calling station from all further long distance transmission facility access and generates an alarm indication to identify a possible facility access problem.

  • Patent number: 4797910
    Abstract: A method and apparatus for identifying the class of an operator assistance call in order to reduce the operator work time for serving such a call. A customer dials 0 or dials 0 plus a directory number and is connected to a program controlled operator assistance system or switch. The switch initially connects the calling customer to a voice processing unit and prompts the customer to speak a command or key a command code. The command or command code is recognized and used to direct the flow of the control program to selectively defer a connection to an operator position. For example, for person-to-person calls, the operator position is only connected after the called customer terminal answers. Advantageously, such a method and apparatus substantially reduces operator work time for broad classes of frequently used operator assistance services.

  • Patent number: 4790005
    Abstract: Information(s) to be processed for call set up, as well as for testing and maintenance are supplied to a switching unit. The former are prioritized. A loadability measuring circuit, which compares actual-loading with reference-loading during leveling longer period, short term fluctuations, and continuously sets an adjustment standard related to the inflow of information, which is pre-supplied to a corresponding counter, for continuing inflow measurement, then measures loading caused by information of both kinds, measures instead, average corresponding reduced reference-value dependent, reference-actual comparison, for the case where this loading is too high, only the loading dependent upon call set up information to be processed. The adjustment standard is only reduced when the latter loading is too high, it is increased instead when the latter loading, as well as the loading dependent upon both kinds of information is too low.

  • Patent number: 4782519
    Abstract: A method and apparatus is described for providing extended subscriber features, e.g., equal access, to otherwise non-conforming central offices of a telephone switching system. According to the invention, a register module is interposed between the subscriber line and an input of the central office for intercepting digits from the subscriber line intended for the central office and for receiving subscriber information from the central office identifying the subscriber line. The register module includes a memory having a plurality of address locations and a control circuit for analyzing the intercepted digits to determine whether processing of the subscriber call requires an extended subscriber feature. If so, the intercepted digits are processed to generate a coded signal, the coded signal including the address location where the stored digits and the subscriber information resides in the memory.

  • Patent number: 4757529
    Abstract: In a telecommunication switching system, incoming calls of various call types directed to a group of associated subscriber terminals are queued by call type and distributed on a priority basis. A separate queue is created for each call type and a table is provided which defines a number of priority levels and the call types to be served in each priority level. A priority frequency array is used for each of the terminals to assure that each terminal serves calls at the various priority levels with a prescribed frequency. When calls of different types but having the same priority level are waiting to be served, the oldest call will be selected on the basis of a time-of-day stamp recorded with each call on queue.
