摘要： PURPOSE:To accommodate subscribers at a remote location efficiently through the connection of coarse coupling having aN error control function. CONSTITUTION:A subscriber termination module (SLM) 1 has no major exchange function but has only a function of controlling and concentrating plural subscriber lines only, and each SLM 1 of remote stations 4-1 to 4-4 is connected to a line processing module (CHM) 2 in a center station 5 or a remote station 4-3 through an inter-module outside line 6 being a coarse coupling connection means having an error control function. Each CHM 2 of the stations4-2, 4-3 or the station 5 accommodates the SLM 1 in the inside of the station and the SLM 1 at a remote location to make mutual exchange connection and the CHMs are in exchange connection mutually and via another optional CHM 2 and an inter-module coupling device(IMC) 3. Thus, the CHM 2 and the IMC 3 are connected by the line 6 being a coarse coupling connection means having an error control function. Thus, subscribers at a remote location are accommodated efficiently.

摘要： PURPOSE:To send a signal integrally without splitting the transmission area of a synchronizing signal and an asynchronizing signal by splitting a synchronizing signal string and an asynchronizing signal string into a fixed length of transmission block referred to as a cell. CONSTITUTION:When a terminal equipment 20 of a remote station 2 sends a signal to a terminal equipment 20 accommodated in other station 2, the signal sent from the terminal equipment 20 is split into a fixed length of transmission block referred to as a cell in its own remote station 2 independently of the synchronizing signal string and the asynchronizing signal string and the result is sent to a transmission line 300. When a center station 1 receives the cell via the transmission line 300, a head including an address of a destination terminal equipment 20 is added and the result is sent to the transmission line 300. The signal sent from the terminal equipment 20 is converted into a cell and sent to the transmission line 300 independently of the synchronizing signal or the asynchronizing signal. Thus, the synchronizing signal and the asynchronizing signal are sent integrally similarly.

摘要： PURPOSE:To use a transmission line efficiently by allowing each station to switch the border of a communication band between a synchronizing signal and an asynchronizing signal on a loop communication network depending on time simultaneously so as to attain the switching of the border in a short time with a simple control. CONSTITUTION:In receiving a border setting request from a communication control section 43, a communication band management section rewrites a side A being a side to be rewritten commanded by a switching display section 18 at the reception according to a new border channel number #i-1 by a write control section 6 and uses a timer setting section 15 so as to set a border switching timing (t) to a timer 14, which is started. In counting the setting timing value, the timer 14 applies display switching command to the display section 18. The display section 18 inverts the switching display to the write control section 6 and the readout control section 9. Thus, the band storage section 1 is brought into the state of side A readout, side B write from the state of side A write and side B readout. Thus, in receiving a request from a line function section 31 or the like, the control section 43 reads out the band of a synchronizing or asynchronizing signal from the side B to apply the communication at a new band.

摘要： PURPOSE:To facilitate interface between a controller and a higher device corresponding to a higher device identification number by providing a circuit, which arbitrarily distributes interface between a communication controller and plural higher devices, and a control circuit which controls this distributing circuit based on transfer requests from the controller and higher devices. CONSTITUTION:Plural higher devices 20 are connected to a communication controller 10a, which uses high-level data link control procedures HDCL, with a service access interface SAPI distributing control circuit 41 and an interface distributing circuit 42 between them. An open flag is detected from serial data received by a serial data interface SDI 11 of this system, and an address, data, or the like following this flag is reported to a CPU 12. The CPU 12 reports the transfer indication of data, which the CPU 12 reports to devices 20 and 30, to a DMAC 15 after performing the order reproducing control of effective data transmitted to and received from the SDI 12 and the LAPD processing like link control, thus facilitating interface.

摘要： PURPOSE:To transfer information by the use of a general purpose memory by providing a buffer memory commonly used for plural processors. CONSTITUTION:A page memory (buffer memory) PM can write and read the information based on the designation of reading and writing from the respective ports P1, P2 of the plural processors for mutually transferring the information. Access timing parts TM1, TM2 receive pulses to a terminal C from a timing generator in the respective timings for every constant time and when a terminal goes to H level at that time, respective access timing signals TMA1, TMA2 of H are outputted from an output Q. When access request latch parts AL1, AL2 receive a P1 write signal W1, a P2 write signal W2 or a P1 read signal R1, a P2 read signal R2 or H, respectively through OR gates OR1, OR2 to the terminal C, they latch them to bring the output Q to 'H'.

摘要： PURPOSE:To improve the processing efficiency of information transfer by setting a data buffer information area storing a final information address and a transfer information area storing transfer information. CONSTITUTION:An equipment 20 of a layer 3 writes transfer information on a data buffer of a common memory 40, e.g., a transfer information area 44-0 of a buffer 41-0. When the transfer information is long and it is required to provide a chain, chaining information C is brought to 1 in a chaining information area 42-0 and an idle data buffer to write the succeeding transfer information, e.g., DBNO:1 of 41-1 is written on an information area 43-0. Then the device 20 informs a reception request SRQ, in this case, DBNO:0 written at first on the transfer information to a device 10a of layer 2 via an input port 17. The device 10a reads the informed data DBNO:0 and reads the chaining information C of the buffer 41-0.

摘要： PURPOSE:To prevent impairing of communication with other terminal equipment by connection of a testing function to a terminal equipment to be tested and to a normal terminal equipment for testing by connecting the terminal equipment to be tested and two terminal equipments of normal terminal equipment to a testing device provided on the exchange side by a switching device, and setting only two terminal equipments to testing mode. CONSTITUTION:A terminal equipment (TE) 1-1 inputs to a terminal testing device (TSTE) 6 informing of starting of test of a terminal equipment (TE) 1-0. A signal sent to the terminal equipment (TE) 1-0 is added as input information. The terminal testing device (TSTE) 6 sends out a signal to the terminal equipment (TE) 1-0 by following up a command from the terminal equipment (TE) 1-1. The terminal equipment (TE) 1-0 operates by following up the signal from the exchange side, and sends out a reply signal to the exchange side. The exchange side receives the signal from the terminal equipment (TE) 1-0 in the terminal testing device (TSTE) 6, and sends out the signal from the terminal equipment (TE) 1-0 to the terminal equipment (TE) 1-1. The terminal equipment (TE) 1-1 compares the signal sent out previously with a signal sent back based on the sent signal, and checks the normality of the terminal equipment (TE) 1-0.
