摘要： PURPOSE:To provide a monitor emulator port in common to protocols by providing a protocol test module with the monitor emulator port and connecting a protocol handling module and the protocol test module with a switch module between them. CONSTITUTION:A switch module 6 is provided between ISDN No.7 ISUP subscriber's lines 1 and 2 and ISDN subscriber's line D channel and No.7 ISUP protocol handling modules 3 and 4. The monitor emulator port of protocol test is provided in a protocol test module 5 in common to all protocol handling modules 3 and 4, and not only lines 1 and 2 and protocol handling modules 3 and 4 but also protocol handling modules 3 and 4 and the protocol test module 5 are connected by the switch module 6 in accordance with the indication from a switch control module 7. Thus, the monitor emulator port is provided in common to protocols.

摘要： PURPOSE:To control the time series information with low cost by storing the information on each unit time band in the order of the residual obtained by dividing the difference between the start time point of each time band and a reference time point by the unit time. CONSTITUTION:If a request is given to a computer system for reference to the information on a certain unit time, a central control unit 5 calculates the start time point of the reference unit time band from the information on the reference unit time band caused by a reference request given from an input/ output device 6. Then the unit 5 uses the residual obtained by dividing the difference between said start time point of the reference unit time band and the reference time point stored previously in a main memory by the unit time as the index value and reads the information on the corresponding unit time band out of a time series information memory 1 to send it to the device 6. In case a switch request generator 3 has a request to switch the time band for each unit time, the unit 5 uses the residual obtained by dividing the difference between the switch time point and the reference time point as the index value and performs the initialization for the information on the corresponding unit time band of the memory 1.

摘要： PURPOSE:To achieve economization without spoiling the advantage of a store and forward switching type facsimile communication system, by immediately transferring data without storing it when the free state of an incoming terminal is discriminated. CONSTITUTION:Picture information from an originating terminal FAXA is stored in a storing and converting device STOC only when the central processor CCO of a switchboard ES-FX judges that the standard CL1 of the originating terminal FAXA and the standard CL2 of a terminating terminal FAXB extracted from a subscriber file S are different from each other, or when the terminating terminal FAXB is in a busy state. When the standard CL1 and standard CL2 are coincident and the terminating terminal FAXB is in a free state, a picture signal is transferred immediately through an instantaneous circuit SIOT and never stored in the storing and converting device STOC.
摘要翻译：目的：为了实现节省，而不破坏存储和转发切换式传真通信系统的优点，当鉴别入站终端的空闲状态时，立即传送数据而不存储。构成：只有当交换机ES-FX的中央处理器CCO判断出始发终端FAXA的标准CL1和终端终端FAXB的标准CL2被提取时，始发终端FAXA的图像信息被存储在存储和转换装置STOC中来自订户文件S彼此不同，或者当终止终端FAXB处于忙状态时。当标准CL1和标准CL2一致并且终端FAXB处于空闲状态时，图像信号立即通过瞬时电路SIOT传送，并且不存储在存储和转换装置STOC中。

摘要： PROBLEM TO BE SOLVED: To provide a caller no-charge communication system by which connection to a plurality of enterprise servers is attained with a single line in a line exchange network. SOLUTION: In the system, an enterprise, etc., pays communication charge in the line exchange network without claiming the charge to a general user through the use of the incoming charging line of the line exchange network which is contracted between the enterprise, etc., and a communication undertaker when voice and data communication is performed between the general user and the enterprise via a network. A route is formed, which is connected to the enterprise servers by way of an IP network after a signal is taken-out from the line exchange network as an IP packet signal by using not only the line exchange network but also a signal converting device and a connection controller for connecting the general user and the enterprise server. An originator free line in the line exchange network is shared by the plurality of enterprises. The distribution of connection to the enterprise servers and the itemized details of communication charge are processed in the connection controller.

摘要： PURPOSE:To effectively use a storage area by dividing the storage area for each of originating and terminating terminals and indicating correspondence relations by a bidirectional chain and storing a terminating terminal normalization number in each terminating terminal call information area to specify the terminating terminal. CONSTITUTION:A main call information area 1 provided for every call has an originating terminal call information area internally, and each of auxiliary call information areas 2-1-2-n has one terminating terminal call information area. The main call information area and auxiliary call information areas are related by bidirectional address linkage. The main call information area can connect plural auxiliary call information areas. Terminating terminal normalization numbers are stored in individual auxiliary call information areas for the purpose of distinguishing plural terminating terminal call information areas from one another. Terminating terminal normalization numbers are checked from the main call information area along the bidirectional address linkage to specify the auxiliary call information area where terminating terminal call information area to be retrieved is stored.
