Abstract: Architectures, arrangements, systems and/or methods for an Internet protocol (IP) telephony system for enterprise applications that is efficiently provisioned and maintained are disclosed. In one embodiment, a single platform uses a label allocation and routing scheme to provide overlapping dial plans for multiple customers, E.164 mapping and enhanced regulatory enhancements for both wireline and wireless telephony devices.

Abstract: Number portability is a service where a subscriber can keep his old telephone number within a portability cluster and thus retain easy contactibility. Because of number portability, a called address, i.e. B-number, no longer refers to the subscription network/number range owner and the old rule “the number range of the called party reveals the tariff level” is no longer valid. To overcome this defect all intelligent network-like service invocation requests are routed (3-2) via a network node performing a number portability function to the network node controlling the service. The node performing the number portability function performs (3-3) a mapping of the B-number and relays (3-4) the service invocation requests indicating the subscription network/number range owner.

Abstract: When telephone calls are placed by dialing a special number such as an “800” number, the dialed number is converted to a specially configured translation number that includes a destination output set of digits which are preferably the last four digits of the dialed number. This translation number is transported over the network from an originating switch to a terminating switch which then outputs the output set to the destination. Advantageously, the terminating switch also replaces the prefix portion of the translation number with an output prefix consisting of at least the NXX portion of the dialed number and outputs this prefix along with the output set to the destination for use in call tracking.

Abstract: A method apparatus for finding and assigning both commercially valuable and vanity (CSV) numbers in a telecommunications system that permits number portability. CSV Numbers are identified by a rules based process that combs the unused number database for valuable combination and saves those numbers in a special database. Those numbers that are not so identified stay in the unused database for general assignment. To assign a CSV number, a similar process is used to generate candidate numbers based on a desired keyword, and then the candidate numbers are used to query the special database and even the general unused number database to get available candidates. The available candidates are offered to the requesting user and the user may accept or decline.

Abstract: A translator in an element of a wideband network transforms a format restored by a CCITT information cell into other predetermined formats. It performs this function by inserting cells from a microprocessor into network data flow in asynchronous transfer mode (ATM) and extracting from the network data flow cells addressed to the microprocessor. The translator includes an input portion for receiving input data cells from the network data flow and for modifying a header of cells in the input data so as to adapt them to perform functions in the ATM layer. Preferably, the translator is implemented as an integrated circuit which serves as an interface between the network and the microprocessor, and which configures and manages asynchronous transfer mode multiplexer functions.

Abstract: The processing of a telephone call identified in part by an area code associated with a particular geographical area results in forwarding the call to telephone equipment located in the geographical area. Such processing is enhanced by associating a unique area code with an entity other than a geographical region or telephone service and then forwarding a telephone call identified in part by the unique area code to telephone equipment associated with the entity even though that equipment may be located in a geographical area associated with a different area code.

Abstract: A method and apparatus for processing and routing termination telephone calls is disclosed. A termination telephone call is one that terminates at a specific pre-defined shared or specific pre-defined dedicated termination trunk group. The pre-defined trunk group is connected to a pre-defined termination switching device. A termination telephone number is translated into a termination routing address. The termination telephone call is routed via a telecommunications network to a termination switch as specified by the termination routing address. The call is then terminated to a dedicated or shared trunk group which is also specified by the termination routing address. The dedicated or shared termination trunk group is directly connected to the termination switch.

Abstract: A calling card subscriber is allowed to choose at least some of the digits of his or her calling card number to form a virtual card number. Associated with the virtual card number is a standardized card number i.e., a number conforming to the Bellcore calling card numbering plan. When the subscriber uses the virtual card number to make a calling card call, the virtual card number is mapped into the standardized number. The latter is then used by the telephone system for subsequent validation and billing.

Abstract: A special feature telephone dialing and switching application system for interconnection to and interaction with the switching system of a central telephone office for converting subscriber-created telephone numbers, including a recognition sequence of one or more digits having alternative alphabetical letter significance, to standard assigned telephone numbers including a 3 digit switch sequence number and a 4 digit recognition sequence number. The recognition sequence of digits of the subscriber-created telephone numbers are followed by the # symbol digit of key dialing telephones and are preceded by a special switch sequence number assigned to the special feature application system within the number phone area code serviced by the central telephone office.

Abstract: A communication network uses a network switch number (NSN) and a class-of-service classification (COS) code to route calls through the network. When a call is received at an originating switch of the network, the dialed number is used to select the NSN which identifies a network terminating switch which connects to the called party. The network uses received call signaling information and stored trunk information and possibly network database information to determine the COS code. The COS code is also used at the terminating switch to identify the type of service trunk to connect to the called party. In another feature, only the network switch number is used to route the call over the network. In accordance with yet another feature, the COS code may be used to select specific network trunks without requiring the specification of the NSN.

Abstract: A circuit for translating predetermined telephone numbers to new digit sequences, referred to as the translated number, is disclosed. Each of the original telephone numbers consists of a first sequence of digits, referred to as the switch sequence, followed by a second sequence of digits, referred to as the recognition sequence. Additional digits may be present after the recognition sequence. The corresponding translated telephone number consists of the switch sequence of the original telephone number followed by a second sequence of digits, referred to as the end sequence. Telephone numbers which do not being with one of the specified switch sequences are allowed to pass through the present invention unchanged without the introduction of a delay.

Abstract: In a distributed processing telecommunication switching system comprising a plurality of switching modules, the individual modules control substantially all telephone call control processing actions, including the selection of an available port of a multiport hunt group, without requiring the assistance of a central processor. Each module includes a processor, a plurality of ports connected to customer lines and interoffice trunks, a plurality of outlets for setting up intermodule connections, and a switching network for interconnecting ports and outlets within a module. The module processors communicate with each other by a high speed common data communication facility connected to all processors. This data communication facility is used for communicating intermodule call control messages and port availability data to allow port hunts to be accomplished without using a central processor.

Abstract: 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.

Abstract: A distributed control switching system where the system control units cooperatively perform the terminating port determination function. In particular, the directory number translation function is done in a manner allowing flexibility in assigning directory numbers to switching system ports but minimizing the magnitude of the storage facilities required in each control unit. Each control unit stores the complete directory number translation for certain directory numbers but stores an index referencing other control units for the other directory numbers. Advantageously, the control units referenced are not necessarily the same ones that are associated with the ports defined by those other directory numbers. Thus the call setup sequence frequently involves three control units-the units associated with the originating and terminating ports, and an intermediate unit which stores the directory number translation information for the received directory number.
