摘要： In an Internet system, a plurality of servers (8), are connected to gateways (55), to which a plurality of subscribers, Subscriber 1, ..., Subscribern, are coupled. A closed user group (CUG) is designated by subscribers which access a specific server, and messages within a CUG are directed to the specific server by header information in messages transmitted by subscribers who are members of the CUG, the header information serving to identify the specific server which serves the CUG.

摘要： A telephone subset is provided with a plug-in module which includes software in memory (12) to enable the subset to access exchange based facilities such as call divert and calling line identification. The subset includes signalling circuitry (9) controlled by a microprocessor (3) in response to the software to communicate with the exchange. The microprocessor also controls an LCD (7) to display messages in the software to guide the user of the subset in accessing the exchange based facilities. The LCD includes labelled displays to provide a continuous display indicating which facilities are activated. The modules are interchangeable to permit access to new facilities at the exchange.

摘要： A method and apparatus for providing a controlled credit facility in a telephone subset. The subset is provided with a central processing unit (CPU) (3) and a keypad (4). The CPU is programmed by the proprietor of the subset with the keypad. After validation of a personal identification number, the proprietor can enter data representing a predetermined credit limit in a memory of the CPU. A client may then establish a connection via the PSTN using the subset. When the connection is established the CPU deducts stored charge unit data from the memory at predetermined periods until the credit limit is reached, whereupon the CPU disconnects the subset from the PSTN.
The subset may be coupled to a facsimile machine and the controlled credit facility used by a client for facsimile transmissions.摘要翻译： 一种用于在电话子集中提供受控信用设施的方法和装置。 该子集设置有中央处理单元（CPU）（3）和键盘（4）。 CPU由子板的所有者用键盘编程。 在验证个人识别号码后，所有者可以在CPU的存储器中输入表示预定信用额度的数据。 客户端然后可以使用子集通过PSTN建立连接。 当建立连接时，CPU以预定的时间间隔从存储器中扣除存储的充电单元数据，直到达到信用限制，于是CPU将该子集与PSTN断开连接。 该子集可以耦合到传真机和由客户端用于传真传输的受控信用设施。

摘要： Dans le circuit d'échantillonnage décrit, qui sert notamment à l'échantillonnage d'amplitudes de tension et de courant dans un kilowattheuremètre pour courant alternatif, les signaux provenant de transducteurs (1 et 2) et représentant les amplitudes de tension et de courant respectivement sont appliqués sélectivement à un convertisseur analogique/numérique (4) au moyen d'un multiplexeur analogique (3) sous la commande d'un processeur (5), lequel fait varier la séquence dans laquelle les signaux sont appliqués au convertisseur. Le processeur effectue des calculs sur les valeurs mesurées par le convertisseur afin de déduire le nombre de kWh.

摘要： An apparatus for controlling data flow through a subsystem (12) of a data communication network (10) includes a plurality of network interface devices (20) connected to a networking medium (14).
Each network interface device (20) comprises a data transport controller (32) which includes means for distributing said data traffic through said network interface device (20), whereby said distributing means are autonomously adaptive to the traffic across each said network interface device (20), and further means, responsive to said data traffic of said subsystem (12) for invoking data flow control communication protocols within each network interface device (20).摘要翻译： 用于通过数据通信网络（10）的子系统（12）控制数据流的装置，包括连接到一个网络介质（14）的网络接口设备（20）多个。 每个网络接口装置（20）包括一个数据传输控制器（32），其包括装置，用于分配所述数据业务通过所述网络接口装置（20），由此，所述输送装置是自主地自适应于横跨每个所述网络接口设备的流量（20 ），和另外的装置，响应于所述子系统（12的所述数据业务）的每个网络接口装置（20）内调用的数据流控制的通信协议。

摘要： A sampling circuit, particularly for sampling voltage and current amplitudes in an AC kWh meter, in which signals from transducers (1 and 2) representing the voltage and current amplitues respectively are selectively applied to an analogue-to-digital converter (4) by an analogue multiplexer (3) under the control of a processor (5) which varies the sequence in which the signals are applied to the converter. The processor performs calculations on values measured by the converter to derive the kWh.

摘要： A microprocessor fault logging arrangement includes means for detecting hardware and software faults 3, 4, 8, which produce an interrupt signal which is applied to the non-maskable interrupt input NMI of microprocessor 1 and, via delay 5, to the RESET input of microprocessor 1. The NMI input causes microprocessor 1 to store the state of selected system parameters in a log of fault records stored in non-volatile memory 2, the selected parameters being stored for fault analysis each time an NMI input signal is generated. The delay 5 allows sufficient time for the selected parameters to be stored in the memory 2 before the microprocessor is reset.

摘要： A tone detection method for a telephone subset to detect tones in the presence of noise and speech. According to the method the period of an input signal containing the valid tone is measured at a fixed sample rate (say 10 ms). The measured periods are compared to that expected of a valid tone and a pass/fail decision is made for each sample and stored in a buffer whose length is chosen to be longer than a complete cadence cycle of the valid tone (say 1 second). By examining the buffer it is possible to calculate a percentage pass rate for any period. If the pass rate is above a predetermined threshold then a valid tone is present.
