Abstract: A method and apparatus for user data traffic handling for an EVDO enabled hybrid mode mobile device, the method having the steps of: blocking a system selection at the mobile device until no EVDO traffic state exists, the blocking step includes either monitoring whether a user changes a scan mode on the mobile device; and if the user changes the scan mode, checking whether the mobile device is in an EVDO traffic state; and if yes delaying a system selection until the EVDO traffic state is ended, or monitoring whether a user is in an EVDO traffic state, and if yes, preventing a user from accessing a scan mode menu on the mobile device.

Abstract: The present invention provides a method and apparatus for performing line qualification tests, and binning the results of such testing. The lines are tested to determine or estimate various characteristics of the line. Physical characteristics of the line may be estimated (e.g. line length, line gauge, insertion loss). The presence of devices on the line such as load coils, bridged taps, terminations and the like may also be determined. A prediction of the data rate the loop can support is made from the measured and estimated line conditions. The results are binned according to certain criteria and to provide an easily discernable status of the line. The binning can be performed by a computer using software designed specifically for this purpose. The binned results may include a first category indicating the line cannot support a certain level of high speed access. The binned results may also include a second category indicating the line can support a certain level of high speed access.

Abstract: A system and method provide a call service features in response to call control information conveyed by a monitored bearer channel in a telecommunications network. A bearer channel monitor captures the call control information and relays the information to a call control application server. The call control application server analyzes the call control information, and provides call control instructions to a call control node that operates in the telecommunications network to effect the call service. The call control node serves as one or more virtual switching points in the network to directly control call routing without disconnecting a called or calling party, unless required as part of a service feature. Control from a center of the telecommunications network provides rapid and efficient call control without use of edge devices or duplication of bearer channels in the network.

Abstract: A wireless transmitter transmits data with at least two different levels of required quality on the same wireless channel. The transmitter has a multiplexer that multiplexes the data into frames, each frame containing data with at least two different levels of required quality, and a power controller that controls the transmitting power of each type of data separately within each frame, thereby avoiding the use of excess transmitting power.

Abstract: A technique for detecting and responding to a loopback condition on an ISDN PRI of a telecommunications switching system. The technique involves storing the Call Reference Value of the most recently transmitted call SETUP command as the Last Sent CRV. An incoming call SETUP command is considered to have looped back when it is assigned a Call Reference Value identical to the Last Sent CRV, and it requests a PRI channel that is occupied. The PRI is considered to be in a loopback condition after a predetermined number of call SETUP commands have looped back. The PRI can be removed from service while the loopback condition persists.

Abstract: Method and apparatus are provided for re-synchronizing a group of B channels in an ISDN network using the BONDING Mode 1 specification. Re-synchronization is achieved without the need to first disconnect the affected group of B channels from the network. Thus, the reliability of the bonded channels is improved while maintaining a simpler architecture than those associated with BONDING Modes 2 and 3. The solution offers improved channel reliability, improved network performance and reduced network load when channel re-synchronization becomes necessary.

Abstract: When an external terminal is signed on to a communications system, a data link is set up between the external terminal and a teleworking subscriber line module of the communications system. Until the external terminal is signed off, terminal-oriented signaling information, such as is usually available within the framework of a signaling protocol between internal terminals and the communications system, is transferred between the external terminal and the communications system via the data link.

Abstract: To avoid searching for objects that are not effectively configured and therefore to mitigate connectivity and system failure, an intermediate routing object index (100, 103) is created to each and every object in a system (36). In a telecommunications system, for example, an object is only operational at a node (10, 30-34), such as a switch, upon receipt of all necessary configuration messages (102) from an overall system controller (12) responsible for overseeing operation of the node (10, 30-34) and the set-up of a connection. The routing object index stores (103, 108) an indication of the receipt of the necessary configuration messages and so provides a direct indication of whether the object exists and whether it is effectively configured.

Abstract: A cleaning system retrieves a telephone number from a telephone number list to regard as a called party number and sends a SETUP message to the network, in which a SPEECH or an AUDIO is designated as a bearer capability. In case that an ALERTING or CONNECT message is sent back from the network, the system sends a DISCONNECT message to the network immediately to perform a clear sequence and determines the telephone number effective. In case that a DISCONNECT message is sent back from the network as a result that a call has not been accepted, the system also performs a clear sequence immediately and determines if the telephone number should be treated as an effective number or a null number according to the cause content sent from the network.

Abstract: A computer connected to an ISDN central office switch via an ISDN digital subscriber line, provides management information regarding activities of a plurality of telephone agents. The computer has shared call appearances with a number of telephone agent stations and receives shared call appearance associated messages from the switch reflecting call handling messages exchanged between the ISDN switch and each of the agent stations. The messages are interpreted by the computer, which generates station status information and management information such as the number of calls handled, average holding time per call, etc. The computer may be connected simultaneously to several central offices via ISDN subscriber lines and generate management information for a group of geographically separated agents, such as home telemarketing agents operating out of their individual homes and connected to different central offices.

Abstract: The inability of an ISDN equipment user to properly configure ISDN terminal equipment, even when provided with correctly assigned switch protocol, SPID and LDN parameters by a telephone service provider, is successfully remedied by a SPID/switch protocol detector. Upon being invoked by the user, the routine proceeds to conduct an iterative search of stored SPID formats associated with different central office switch protocols. SPIDs are assembled in accordance with the iteratively accessed SPID formats and directory number information that has been entered by the user. If an attempt to register a SPID is successful, the routine places a test call. If the test call is successful, the SPID and its associated switch protocol will have been identified, and the terminal equipment may place a call.

Abstract: An H channel for controlling the use of network is selected to effectively use lines when a request for H communication is issued. An ISDN line channel selection method, whereby a plurality of B channels are bundled and serve as an H channel, and the B channels are selected according to a condition under which each of the B channels to be used is registered as either an H channel dedicated class or H channel shared use class. The method includes the steps of temporarily changing the b channels from the H channel shared use class to the H channel dedicated class if the B channels in the H channel shared use class are busy when a request for connection of the H channel has been received from a transmission side, queuing until the B channels that form the H channel dedicated class are idle, and connecting the transmission side to the H channel when the B channels that form the H channel dedicated class are idle.

Abstract: A communication switching system has a plurality of switch nodes with each of the switch nodes responsive to a failure of the primary signaling channel that is providing the common signaling channel in a facility access service (FAS) group to immediately switch to the secondary signaling channel of the FAS group. This switching occurs quickly so that no calls are dropped within the FAS group. Any logical links being communicated on the primary signaling channel are transferred to the secondary signaling channel with no data packets being irreplaceable lost. A first physical object is established to control a physical protocol on the primary signaling channel, and a second physical object is established to control the physical protocol on the secondary signaling channel. Further, a single software object is established to always control the first layer of software protocol on the common signaling channel whether that is the primary signaling channel or secondary signaling channel.

Abstract: In the method, a call setup in an ISDN communication network (ISDN) is initiated from a further communication terminal equipment (KEX) to a communication terminal equipment (KE) whose performance features are to be influenced. At least one setting information (esi) that influences a performance feature as well as an activation signal (aki) is communicated to the communication terminal equipment (KE) via a user--user information element (uui) that is standardized in the draft prETS 300 286 and inserted into the ISDN signaling information (si), and the call setup is subsequently ended. Initiated by the activation information (aki) and during the set up connection or after the cleardown of the connection, the respective performance feature of a service is automatically influenced in the communication terminal equipment (KE) according to the communicated setting information (esi). A remote control of performance features of services in ISDN communication networks is possible with the method.

Abstract: A cleaning system retrieves a telephone number from a telephone number list to regard as a called party number and sends a SETUP message to the network, in which an unrestricted digital information is designated as a bearer capability. In case that an ALERTING or CONNECT message is sent back from the network, the system sends a DISCONNECT message to the network immediately to perform a clear sequence and determines the telephone number effective. In case that a DISCONNECT message is sent back from the network as a result that a call has not been accepted, the system also performs a clear sequence immediately and determines if the telephone number should be treated as an effective number or a null number according to the cause content sent from the network.

Abstract: A system for use by a multiplexing telecommunications interface that allows the interface to communicate with a larger variety of digital subscriber loop protocols, such as ISDN. For example, a remote terminal may include common equipment that allocates a limited bandwidth to particular channel cards. Such channel cards control the flow of information between a digital subscriber loop and a digital transmission facility. If the bandwidth allocated to a particular channel card is insufficient, a provisioning channel card may be used which will signal the common equipment that it exists and should be allocated to a bandwidth. However, the provisioning channel card will effectively provide its bandwidth to at least one other channel card, which will use the additional bandwidth to meet the requirements of a particular protocol, such as ISDN.
