摘要： The invention is to offer a technology with which a call process, a band setting process in particular, from a unit of terminal equipment to a network can be effectively performed, in relation to a communication system in which a communication band necessary for a unit of terminal equipment is secured by transmitting a SETUP message to a network from the terminal equipment as in the case of a call procedure in B-ISDN, etc. In the communication control of the terminal equipment connected to the network, when a call is made if the securing of a band in the network is impossible, the call is cut off, but if the band area in the network is insufficient for an initial band value stored in a SETUP message, a revised band value is produced by subtracting a certain value from the initial band value, and a SETUP message with the revised band value is retransmitted to the network.

摘要： A routing method routes cells which are transferred through one of a plurality of paths within an asynchronous transfer mode (ATM) switching system selected by routing information. The routing method includes the steps of adding first routing information to incoming cells at an input stage of the ATM switching system when supplying the cells to the ATM switching system, generating a route switching confirmation cell in response to a route switching instruction and for adding second routing information to incoming cells thereafter so as to supply the route switching confirmation cell and the cells added with the second routing information to the ATM switching system. The second routing information is different from the first routing information and is determined by the route switching instruction, comparing routing information. The method also includes the cells with the second routing information at an output stage of the ATM switching system in response to the route switching instruction, and outputting each cell from the ATM switching system having routing information different from the second routing information as it is. The method also includes temporarily storing each cell from the ATM switching system having routing information identical to the second routing information and reading out and outputting the stored cell after the route switching confirmation cell is output from the ATM switching system.

摘要： An internal timing information producing portion produces internal timing information IRTS1 to IRTS4 which is the timing information on a data reception clock by using a network clock C.sub.N and the data reception clock C.sub.RU. A calculator calculates the difference between the internal timing information IRTS1 to IRTS4 and the transmission timing information RRTS1 to RRTS4 contained in a received cell, and a data reception clock producing portion adjusts the timing of the data reception clock C.sub.RU so that the difference is zero and outputs the adjusted timing. An ATM cell decomposing portion outputs the user data D.sub.RU in synchronism with the data reception clock C.sub.RU which is input from the data reception clock producing portion.

摘要： By transmitting an analog CATV signal output from a CATV-HE (CAble TeleVision-Head End) to an HDT (Host Digital Terminal), an analog transmission channel for transmitting the analog CATV signal to an ONU (Optical Network Unit) is included in a path housing a digital transmission channel for transmitting a digital service signal for individual distribution service to the ONU. Furthermore, a digital service signal for multicast service is modulated and converted into an analog service signal by a modulator in the HDT. Then, the converted signal is mixed with the analog CATV signal, and transmitted to the ONU. Accordingly, each of the ONUs is equipped with only a built-in modulator for modulating the digital service signal for individual distribution service.

摘要： Information selectively read out from an information source storing various types of information is repeatedly sent from a center office to a number of terminal equipment units with an error check code added on. The terminal equipment units use the error check code to detect if there is an error in the received information. If the information is received without error, the reception operation is ended for each terminal equipment unit. In this case, there is no interposition of a protocol for confirming if the transmission and reception of the information had been performed normally, so the load on the center office is lightened and it is possible for each of the terminal equipment units to receive the information without error.
摘要翻译：从存储各种类型的信息的信息源选择性地读出的信息从中心局重复发送到附加了错误检查码的多个终端设备单元。终端设备单位使用错误检查码来检测接收到的信息是否有错误。如果没有错误地接收到信息，则对于每个终端设备单元，接收操作结束。在这种情况下，不存在用于确认信息的发送和接收是否已经正常执行的协议的插入，所以中心局的负载减轻，并且每个终端设备单元可以接收信息没有错误。
