摘要： A telecommunication apparatus and method for providing packets to at least one of a first and a second networks are described. A telephone set (15) connects the first network (12) to the second network (14). In one embodiment, the telephone set includes two MAC devices. Each MAC device is in electrical communication with one of the two networks via a communication path. In another embodiment, a packet switching device provides the separate communication paths to the two networks. The telephone set forwards packets received from one network to the other network, generates packets from signals locally inputted into the telephone set and forwards such generated packets to at least one of the networks, and performs actions prescribed by packets received by and addressed to the telephone set. Packets addressed to the telephone set may or may not be forwarded.

摘要： A method and apparatus for communicating a real time media input over a network. The apparatus encodes the input into data packets having a number of frames ordered according to a first variable. A receiving device unpacks and buffers the unpacked data packets for playout according to a second variable. The receiving device generates utility parameters for evaluating a dynamic characteristic of the network that transports the data packets. The receiving device selects a preferred utility parameter and adjusts the first and second variables according to the selected utility parameter. The method includes encoding an analog input into data packets that are transported to a receiving device. The method also includes unpacking the data packets, buffering the unpacked data packets according to a second variable, and generating at least two utility parameters that represent a dynamic characteristic of a network. The method also includes selecting a preferred utility parameter and adjusting the first and the second variables according to the selected preferred utility parameter.

摘要： An improved DC compensation method for use in conjunction with telephony signalling. The method includes defining a frame that includes at least two n-bit codewords. An unsigned codeword is then identified within the frame by applying a rule to the codewords in the defined frame. Next, a sign bit is appended to the unsigned codeword, thereby producing a DC compensating codeword. The sign bit is selected based upon a weighting function of the linear values associated with previously transmitted codewords. The remaining unsigned codewords in the frame are assigned sign bits from user data.

摘要： An intermediate system authenticates end systems, in one embodiment using cryptography. An authentication routine is called on a port when an intermediate system detects any interruption in the physical connection with the port. An embodiment requires a user to supply a secret known only to the user before allowing data to be transmitted. Network data is not fully transmitted or received to any port that has not been authenticated. The invention distributes a user authentication to the point where an end system initially connects to a network, to prevent an authorized reception or transmission of network data that is not prevented under existing network login systems. The invention may be incorporated into an intermediate system, into intermediate system software, or into applications specific integrated circuits designed for use in an intermediate system. The invention may include components that interact specifically with installed components in an end system or elsewhere in a network.

摘要： Indication and interrupt signals generated by a network adapter (3) representing asynchronous events are managed by a host system (1). The network adapter (3) comprises a first mask logic (10) for selectively disabling the indication signals from being stored in a first memory location (10a-c) by the host writing to a first mask register (10). A second mask logic which is coupled to the first memory location (10a-c) also selectively disables the indication signals from being stored in a second memory location (10a-c) creating two levels of status information. The indication signals may also be disabled from being stored in the second memory location (10a-c) responsive to the host writing to a second mask register. The first memory location (10a-c) may be read from the host (1) in order to determine whether a network event occurred during an interrupt service routine, while interrupt means (10) generates an interrupt signal to the host (1) responsive to the value in the second memory location (10a-c). A third level of control is provided by an internal counter which allows for automatic enabling and/or disabling of a plurality of indications and interrupts with and without explicit commands in the host driver subroutines.

摘要： A personal information device (PID) is coupled to an IP Telephony phone in order to provide end-to-end connectivity to another PID through a network. The architecture disclosed includes a pair of internet-enabled phones that are able to establish a call session using a Session Initiation Protocol (SIP) and a Session Description Protocol (SDP). Each phone is also provided with an interface configured to communicate with a PID. Each PID is registered to a corresponding internet-enabled phone using each PID user's SIP URL. The user of a first PID connected to a first phone requests a call to a SIP URL corresponding to the user of the second PID that is connected to a second phone. The SIP URL for the user of the second PID is resolved to the network address of the second phone and connection is established between the first and second phones. The connection includes a media stream for transferring data between each of the PIDs. A data object transmitted by the first PID through its interface with the first phone is transmitted to the second phone through the media stream of the connection between the first and second phones. The data object received by the second phone is transmitted to the second PID through the interface between the second phone and the second PID.

摘要： A method and system for analytically and dynamically generating a repeatable digital probing signal representing an answer tone. The probing signal may conveniently be used by a modem to determine whether characteristics of the communication path between the modem and another end are sufficiently similar to these of a previous communication path, such that a shortened training sequence can be employed between two ends. When the modem initiates communication, the modem applies a predefined algorithm to dynamically generate a sequence of samples representing an answer tone signal. Next, the modem encodes the generated sequence of samples into a sequence of codewords and sends it to a second modem via a transmission path. When the second modem receives each codeword of the sequence, the second modem dynamically generates a respective codeword and compares it to the received codeword. Using the received sequence of codewords and the dynamically generated sequence of codewords, the second modem may determine whether a shortened training sequence may be employed.
摘要翻译：一种用于分析和动态生成表示应答音的可重复数字探测信号的方法和系统。调制解调器可以方便地使用探测信号来确定调制解调器与另一端之间的通信路径的特性是否与先前的通信路径的通信路径的特性足够相似，从而可以在两端之间采用缩短的训练序列。当调制解调器启动通信时，调制解调器应用预定义算法来动态生成表示应答音信号的样本序列。接下来，调制解调器将所产生的采样序列编码成码字序列，并通过传输路径将其发送到第二调制解调器。当第二调制解调器接收序列的每个码字时，第二调制解调器动态地产生相应的码字并将其与接收到的码字进行比较。使用接收到的码字序列和动态生成的码字序列，第二调制解调器可以确定是否可以使用缩短的训练序列。

摘要： Support for priority and IP security packets, and other protocols at the network interface level and in conjunction with FIFO-based packet buffers is provided by allowing out of order processing of certain packets in the FIFO. The optimized character of FIFO for sequential transfer is maintained, while particular types of packets are processed out of order to achieve minimum latency and maximum data security in an intelligent network interface card (10). A buffer (15) stores data packets in an order of receipt. Logic is included in the network interface to transfer packets out of the buffer (15) according to the order of receipt, and according to the respective packet types so that packets having a particular packet type are transferred out of the order of receipt relative to packets having other packet types.
