摘要： Since a transmission route is set in accordance with the number of relaying broad band switching nodes present between two terminating nodes of a plurality of broad band switching nodes, a through-put characteristic, an affecting degree due to occurrence of a defect, the traffic of the entire network is distributed. In addition, when the system is started up, transmission routes with a minimum band width necessary for routing control have been set in all the broad band switching nodes. Whenever a call takes place, a transmission route is set and the band width is variably set by using an intelligent inference mechanism. Moreover, an intelligent distributed control for distributing such an intelligent inference mechanism in the broad band switching nodes is used. Thus, the load of processing a call can be decreased, while the reliability of the network and the improvement of the operating efficiency can be achieved. Furthermore, since the private branch system interface uses a frame which consists of a control window area for controlling its transmission and a cell multiplexing area for multiplexingly transmitting cells, bidirectional transmission between the broad band switching node and a plurality of terminal equipments can be achieved with a single extension transmission line. In addition, since a frame construction which satisfies the ATM method is used, different information transmission speeds can be flexibly selected.
摘要翻译：由于根据存在于多个宽带交换节点的两个终止节点之间的中继宽带交换节点的数量来设置传输路由，因此产生通过特性，由于缺陷发生的影响程度，整个网络都是分布式的。此外，当系统启动时，已经在所有宽带交换节点中设置了具有路由控制所需的最小带宽的传输路由。每当发生呼叫时，设置传输路由，并且通过使用智能推理机制可变地设置带宽。此外，使用用于在宽带交换节点中分发这种智能推理机制的智能分布式控制。因此，可以降低处理呼叫的负担，同时可以实现网络的可靠性和提高操作效率。此外，由于专用分支系统接口使用由用于控制其发送的控制窗口区域和用于多路复用发送小区的小区复用区域组成的帧，所以可以通过以下方式实现宽带交换节点与多个终端设备之间的双向传输：单个扩展传输线。此外，由于使用满足ATM方式的帧结构，因此可以灵活地选择不同的信息传输速度。

摘要： In a communication network in which a plurality of information processors are coupled to a communication medium through medium attachment units (MAUs), a pilot signal generator sends a pilot signal of a reference level to a predetermined point of the communication medium. Each MAU has a gain controller to control the gains of transmission and reception amplifiers. This gain controller adjusts the gain of the reception amplifier when the pilot signal is received in accordance with the reception level thereof and then allows a test signal to be transmitted to the communication medium through the transmission amplifier. The gain of the transmission amplifier is adjusted in accordance with the reception level of this test signal such that the reception level of the test signal becomes equal to the reception level of the pilot signal. Each MAU is provided with a random number data generator and sets the transmission time slot of the test signal in dependence on random number data to prevent simultaneous transmission of test signals from MAUs.

摘要： A time-division multiplexing communication network comprising a central station and a plurality of local stations, in which information signals are transmitted from the local stations to the central station on a time-division multiplexing basis, and the central station transmits information signals to the local stations on a time-division multiplexing basis. The central station sequentially requests that local stations transmit a test signal in order to prevent collision of transmission signals from the local stations. Each local station, of which a test signal transmission is requested, transmits the test signal to the central station. The central station sends back the test signal to the local station which transmitted this test signal. The local station measures transmission delay time from transmission to reception of the test signal, and adjusts transmission timing of the information signal to be transmitted to the central station based on the measured delay time.

摘要： In a communication network system, a central equipment unit transmits, over a down link, a frame signal carrying subframe information signals addressed to respective terminal equipment units, on a time-division multiplexing basis. The frame signal consists of a delay measurement window field carrying address information designating one of the terminal equipment units for delay measurement and a data field carrying the subframe information signals addressed to the terminal equipment units. When a terminal equipment unit is polled from the central equipment unit to measure the delay time, it transmits a response signal to the central equipment unit after a predetermined time interval from the reception timing of the frame signal, such that the response signal arrives at the central equipment unit within the delay measurement window field of the next frame signal. The central equipment unit measures a delay time between the transmission timing of the next frame signal and the reception timing of the response signal, and transmits transmission timing adjustment information based on the measured delay time, and address information of the terminal equipment unit, in an address field of the next frame signal. The terminal equipment unit transmits a subframe signal to the central equipment unit after a time interval, depending on the transmission timing adjustment information, from the reception timing of a frame signal.

摘要： A central station and a plurality of local stations are coupled through a signal transmission path. Data signals addressed to local stations, to which terminal devices such as telephone sets are coupled, are transmitted over the signal transmission path on a time-division multiplexing basis. Each local station sends the data signal onto the signal transmission path at a timing depending on a measured transmission delay time of a signal on the signal transmission path between itself and the central station. One transmission frame consists of subframes of data signals addressed to the local stations and a window frame for transmission delay time measurement. A maximum network length depends on the time duration of the window frame. In order to extend the time duration of the window frame and to increase the maximum network length, data signals for the same terminal device coupled to a local station are multiplexed in one time slot of a subframe.
