摘要： A communications device is presented that allows dynamic bandwidth allocation of an unswitched data path based upon the current utilization of one or more switched data channels. The device operates over the local loop of a digital communications carrier, such as a T1 line, that has a variety of time division multiplexed channels. Each data channel can be configured to operate as a channel dedicated to carrying unswitched data on the unswitched data path, or as a switched channel. Switched channels maintain status information about their current status, allowing switched data communication when the channel's status is active, and permitting the unswitched data path to utilize the channel when the channel's status is idle. In one embodiment, channel status information is passed to a remote unit by altering a redundant robbed-bit signaling bit in a multiframe. In a second embodiment, channel status is determined by monitoring switching information that is already transmitted about the channel. In the second embodiment, a preset time delay is required to properly synchronize bandwidth switching. Unswitched data is transmitted over the switched data channels utilizing all bit locations other than the locations taken by the four robbed-bit signaling bits. A method for dynamically reallocating the bandwidth of an unswitched data path utilizing these same techniques is also presented.
摘要翻译：呈现通信设备，其允许基于一个或多个交换数据信道的当前利用率来对未切换的数据路径进行动态带宽分配。该设备通过具有各种时分多路复用通道的数字通信载体（例如T1线）的本地环路进行工作。每个数据信道可以被配置为作为专用于在未切换数据路径上承载未切换数据的信道或作为切换信道来操作。交换的信道保持有关其当前状态的状态信息，允许当信道状态处于活动状态时进行切换数据通信，并且当信道的状态为空闲时允许未切换的数据路径利用该信道。在一个实施例中，信道状态信息通过改变多帧中的冗余抢占位信令位而被传送到远程单元。在第二实施例中，通过监视已经关于频道发送的切换信息来确定信道状态。在第二实施例中，需要预设的时间延迟来适当地同步带宽切换。利用除了四个抢占位信令位采取的位置之外的所有位位置，通过交换数据信道发送未切换的数据。还提出了一种使用这些相同技术来动态地重新分配未切换数据路径的带宽的方法。

摘要： A system and method for routing IP packets to an aircraft eliminates the need for the exchange of routing information via dynamic routing protocols between the aircraft and ground station routers. An Internet protocol (IP) packet routing table is populated by converting a tail number of the aircraft into a destination subnet address for the aircraft. Forward channel information for a ground router is determined based on the tail number. The method further provides for adding a route entry to the routing table based on the forward channel information and the destination subnet address such that the route entry enables the ground router to delivery IP packets to the aircraft.

摘要： Communicating voice over a packet-switching network is implemented on a telecommunications network that includes the packet-switching network, two coding units coupled to the packet-switching network and to an originating node and a terminating node, respectively, and at least one signaling apparatus. The first of the two coding units is configured to extract signaling data associated with the voice call and transmit the signaling data and its network address to the signaling apparatus. Signaling data for establishing the voice call is received by the signaling apparatus, and a network address of the first coding unit in the packet-switching network is obtained. The second coding unit is controlled to establish a bearer channel with the first coding unit for carrying the voice data through the packet-switching network, based on the network address.

摘要： A hybrid exchange which exchanges the STM data to be transmitted periodically to realize an exchange in unit of the ATM data to be transmitted asynchronously includes asynchronous transmission terminal interface as the interface with an STM terminal, an synchronous transmission terminal interface as the interface with an ATM terminal, an ATM exchange interface as the interface with an ATM exchange, a transmitting unit for transmitting the STM time slot and ATM time slot, and a control unit for controlling the interfaces. The synchronous transmission terminal interface assigns the STM data to be transmitted periodically to the STM time slot, while the asynchronous transmission terminal interface assigns the ATM data to be transmitted asynchronously to the ATM time slot. The STM time slot and ATM time slot are identified by the STM/ATM identifier. The STM time slot is stored by multiplexing a plurality of STM data.

摘要： A communication apparatus properly switches connection by means of a transmission protocol determining section or a reception protocol determining section. In accordance with a transmission request from a telephone or a facsimile machine, the transmission protocol determining section activates either an Internet phone controller or an Internet FAX controller and performs data transmission via either a public switched telephone network interface or a LAN interface. The reception protocol determining section activates either the Internet phone controller or the Internet FAX controller and sends data, received via either the public switched telephone network interface or LAN interface, to the telephone or facsimile machine. With various terminals connected to one another over a LAN, therefore, those individual terminals can be used effectively on an Internet by adaptively connecting telephones, facsimile machines, etc. to the LAN, Internet, public switched telephone network or the like.

摘要： A packet telephone system which employs a packet network that provides virtual circuits. The packet telephone system employs short packets containing compressed speech. The use of the short packets makes possible compression and decompression times and bounded delays in the virtual circuits which are together short enough to permit toll-quality telephone service. The packet telephone system employs an intelligent network interface unit to interface between the packet network and standard telephone devices. The network interface unit does the speech compression and decompression and also responds to control packets from the packet network. Consequently, many telephone system features can be implemented in the network interface unit instead of in the switches. The network interface unit may also be used to provide data connections to devices attached to it. The combination of virtual circuits, with bounded delays, short packets, rapid compression and decompression, and intelligent network interface units makes it possible to build a telephone system with fewer and cheaper switches and fewer links for a given volume of traffic than heretofore possible and also permits substantial savings in provisioning and maintaining the system.

摘要： A secure communication mechanism for communicating credit card or other sensitive information between a user terminal and a server which communicate over a data network (e.g.,Internet). For secure or private communication of sensitive information over a data network, a telephone connection is established between the originating server to which the user is connected for access to the data network and the SP to which the sensitive information is directed. The method and system provide for a secure electronic commercial transaction between a user and a service provider which charges for information and/or services and/or goods, wherein sensitive information includes credit card information transmitted from the user to the service provider, and/or electronic information or services transmitted from the service provider to the user in exchange for payment received from the user.
