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： In a stereophonic voice transmission system for transmitting voice signals of a plurality of channels, a transmitting end encodes main data consisting of at least one channel voice signal among a plurality of voice signals of a plurality of channels and additional data required for reproducing the voice signals of the remaining channels from the main data, and transmits coded main data and the coded additional data to a receiving end. The receiving end decodes the coded main data, and encodes and combines the main data with the additional data to reproduce the voice signals of the remaining channels, thereby transmitting stereophonic voice signals along a transmission line of a low transmission rate, with high quality at low cost.

摘要： A communication terminal apparatus is separated into a housing that is capable of video/voice communications, and a housing that is capable of only voice communications. Since functions of the housing that is capable of only the voice communications are limited, the housing becomes small, can be stored in a pocket or the like, and can immediately go off-hook upon reception of an incoming call. Upon reception of a videophone communication request, the user goes off-hook using the housing that is capable of only the voice communications to immediately make voice communications with the partner terminal, and can switch the communication mode to the video/voice communications using the housing that is capable of the video/voice communications, as needed. Hence, even a communication terminal having a videophone function can comprise a video input/output function without impairing its portability and storability.
摘要翻译：通信终端装置被分离成能够进行视频/语音通信的外壳以及仅能进行语音通信的外壳。由于仅能够进行语音通信的外壳的功能受到限制，所以外壳变小，可以存储在口袋等中，并且能够在接收到来电时立即摘机。在接收到可视电话通信请求时，用户仅使用语音通信的外壳即可摘机，立即与对方终端进行语音通信，并且可以使用该外壳切换到视频/语音通信根据需要能够进行视频/语音通信。因此，即使具有可视电话功能的通信终端也可以包含视频输入/输出功能，而不损害其便携性和可存储性。
