Abstract: A connection manager which requires re-authentication of a user of a permanent virtual connection (PVC). Data transfer may be disabled upon the occurrence of a pre-specified condition, and is enabled only upon proper authentication. An out-of-band connection (e.g., another PVC) may be used for such authentication. The connection manager may disable data transfer by a controlling a customer premise equipment (CPE) serving the managed PVC.

Abstract: A method, system, and associated program code and data structures are provided for a message processing system in which messages are transmitted from source nodes to destination nodes. An “eager” rendezvous transmission mode is disclosed in which early arrival buffering is provided at message destination nodes for a predetermined amount of data for each of a predetermined number of incoming messages. Relying on the presence of the early arrival buffering at a message destination node, a message source node can send a corresponding amount of message data to the destination node along with control information in an initial transmission. Any remaining message data is sent only upon receipt by the source node of an acknowledgement from the destination node indicating that the destination node is prepared to receive any remaining data.

Abstract: The time slot interchange capabilities of modern digital loop carriers are utilized to provide direct connectivity from the calling modem's line to an internet access modem bank through the digital loop carrier, thereby bypassing the local central end office. A call which is to a telephone number of an internet access provider's modem is routed to a bypass initiator. If the bypass initiator detects that the call is from a number which is serviced by a digital loop carrier having a local central end office bypass capability, then the bypass initiator issues a bypass command. The digital loop carrier establishes the bypass connection, but does not break the signaling connection on the initial call which was routed from the digital loop carrier through the local central end office to the bypass initiator. Once the bypass connection has been established, the bypass initiator sends a disconnect signal through the signaling connection of the initial call.

Abstract: A system and method using enhanced processing, responsive to domain name translation requests, to provide selective routing services through a public packet switched data network. The name processing applies to translation of a domain name into a group of Internet Protocol (IP) addresses and to providing routing information for a packet data network such as the Internet. Following name translation into a group of addresses communication is automatically established between a calling terminal and a terminal designated by one of the addresses and determined through processing which effects linkage with the first terminal to respond. The selective routing is particularly advantageous for processing of voice telephone communications through the Internet packet data network based on domain name translations.

Abstract: For facilitating the synchronization management in a system including a synchronized master and a slave unit communicating over a packet switched network (e.g., ATM network), the clock of a synchronized master unit is recovered by the slave unit by, for example an adaptive mechanism. The slave unit may use the recovered clock for transmission over the network. The depacketizing at the master side may then be performed using a clock signal provided directly from the synchronized network, i.e., without recovering the clock via the adaptive mechanism or the like.

Abstract: A switching node for transferring packets, each including a destination address, in a network includes a plurality of input port modules, a plurality of output port modules and a switching fabric, including a packet meta-data processor and a packet switch. Each input port module is connected to a communication link for receiving packets thereover, and each output port module is connected to a communication link for transmitting packets thereover. Each input port module, upon receiving a packet, buffers the packet and generates a meta-data packet therefor identifying the output port module that is to transmit the packet and packet identifier information, and provides it to the packet meta-data processor.

Abstract: An ATM switching apparatus for a switch system is connected between a plurality of trunk connection units connected with a TDM network and an ATM connection unit connected with an ATM network. The ATM cell converting unit converts trunk data, inputted over the trunk connection units, to an ATM cell which is outputted to the ATM connection unit or converts an ATM cell, supplied from the ATM connection unit, to trunk data which is to be outputted to the trunk connection units. Accordingly, the ATM switching apparatus and method have an advantage of mutually operating the TDM network and the ATM network.

Abstract: This invention applies to a mobile station that is able to determine a required data rate based on data buffer usage. If the data buffer indicates a requirement for a high data rate transmission, the mobile station sends a request to a base station to be assigned multiple parallel code channels. If the multiple parallel code channels are granted, the mobile station uses the channels for transmitting data to the base station until either the data buffer becomes empty, or a base station time-out occurs, or the mobile station is signalled by the base station to reduce its data transmission rate, whichever occurs first. The mobile station of this invention is enabled to autonomously control the data rate during an assigned period for high speed transmission, so as to lower the data rate when needed for the purpose of improving coverage and/or to avoid operating in a power limited condition, thereby degrading link quality.

Abstract: A system and method for teleconferencing between conferees connected through a connectionless network and conferees connected through a connection-oriented network having a bridge. A call server connects to a bridge hosting a teleconference among connection-oriented conferees and joins the teleconference. The connection-oriented signal received by the call server is converted into a connectionless signal and sent to authorized, authenticated conferees connected through the connectionless network. The call server receives a connectionless signal from a conferee through the connectionless network, converts the signal to a connection-oriented signal and sends the connection-oriented signal to the bridge. Connectionless signals are stored in a database to be analyzed or sent to other conferees, such as those who were unavailable to join the teleconference as it occurred.

Abstract: In a transmitting electric power control apparatus, non-linear bias characteristic in S/N measurement is previously obtained by measurement, and a conversion table for realizing this reverse characteristic is created in an S/N measuring circuit 10, and when a measured S/N value is output from the dividing circuit 9, the table conversion circuit 1 receives this S/N value as an input and outputs a corrected S/N value from the above-described conversion table, whereby it is possible to provide the S/N measurement with high accuracy, and this corrected and measured S/N is compared with a target S/N, and a demand for increasing and decreasing transmitting electric power is transmitted to a mobile station 53, and, in the mobile station 53, in accordance with the instruction from the base station 20, the transmitting electric power is determined and a coded information signal is transmitted.

Abstract: A method and apparatus for supervising a dedicated control channel when in the discontinuous transmission mode. The mobile station monitors the frames it receives from a base station and maintains a counter of bad, good, and empty frames, referred to as COUNT1, COUNT2, COUNT3, respectively. If a received frame is a good frame, COUNT1 is reset to zero and COUNT2 is incremented. If the received frame is a bad frame, COUNT1 is incremented and COUNT2 is reset to zero. If the received frame is an empty frame, COUNT1 and COUNT2 are unchanged but COUNT3 is incremented. A transmitter coupled to the mobile station is enabled or disabled depending upon which, if any, of the COUNTs reaches or exceeds a designated threshold value. In another embodiment, an average aggregated value reflecting the strength of the pilot signals in an active set, measured at the mobile station, is used for comparison to a threshold.

Abstract: A method of communicating control information in systems that support multiple modulation schemes for communicating voice or data and control information. To provide backward compatibility dedicated control channels use the modulation scheme used in current systems, for example GMSK modulation scheme. Traffic channels and associated control channels use linear modulation schemes that have the same symbol rate. The modulation scheme of the associated control channel uses a reduced signal set of the modulation scheme used for traffic channels. Also, an in-band signalling procedure is used to indicate to a receiving station the modulation type, channel coding and speech coding used for a transmitted burst.

Abstract: A novel system for regulating traffic in a communications network by adaptive rate control is disclosed. In a network system having time sensitive messages that require processing within certain time limits, the load queued at network elements with at least one message processor is dynamically controlled to prevent the message processor from becoming overloaded and thereby causing queued messages from timing out without being processed. A threshold value based on a processing parameter such as when a message times out is compared to an average queuing delay and the controlled load is varied in response thereto. Each message processor determines one or more processing statistics from which a controlled load rate applied to at least one source controller is determined.

Abstract: Bus access is arbitrated among modules connected to a common bus. Each module has a priority level and an arbitration number assigned to it. More than one module can have the same priority level. For each priority level, the arbitration numbers assigned are unique. When two or more modules attempt bus access at the same time, the one with the higher priority level wins access. If the priority levels are the same but one module has already accessed the bus, the module that has been waiting wins access. If the modules have the same priority level and have been waiting then the module with the highest arbitration number wins access.

Abstract: A segmentation and reassembly processor (10) is disclosed for use in interfacing a group of time-division multiplexed lines (25) to a cell-based communication environment (20). The SAR uses a bit-table calendar (100) to schedule cells to be sent to the cell-based network. A cell service decision circuit (50) reads frame events from a frame advanced FIFO (40) and signals a cell builder (60) to assemble cells of data from a frame buffer (70) for transmission to a cell based output (50).
