摘要： PURPOSE:To reduce the scale of a display unit by displaying a transmission line in an abnormal synchronous state corresponding to groups or to transmission lines in a group. CONSTITUTION:A string of signals outputted from a synchronous-state supervisory circuit are sequentially written in shift register 12 through input terminal C1, selector 11 and OR gate 19. After synchronous-state display signals of transmission line No.0 of a group of order zero of respective primary-group transmission lines #0-#15 are all written, sybchronous-state display signals of primary-group transmission line No.1 are written in sequence. In this case, written signals of transmission line No.0 are read out in sequence from the final cell or register 12 and OR results with previously-written information are written through OR gate 19. Next, this information is transferred to shift register 13 and outputted to display output lines 21 #0-#15 and if transmission line No.0 of transmission line #1 would be abnormal, ''1'' is outputted to corresponding output line 21 #1. Among display output lines 23 No.0-NO.23 led from register 15, output ''1'' is sent out to 23 No.0.

摘要： PURPOSE:To make folded connection to subscribers possible by providing a folding designation bit area in an address control memory. CONSTITUTION:Time division multiple data from a subscriber is stored in buffer memory 1 temporarily, and exchange of time slots in one data frame is performed by the access from control memory 2. In this cases, a folding designation bit is set area 23 of memory 2, and exclusive OR 6 between contents of area 22, which are written autonomously with hardware, and contents of area 23 is operated, and the output is written in area 22 at the same address of memory 2 again. Then, alpha and alpha+1 are assigned repeatedly as the write address and the read address to memory 1 for every one data frame, and therefore, transmission data from the subscriber of time slot t1 is returned to the same subscriber.

摘要： PURPOSE: To process an optional communication picture among many and unspecified terminals by using a control signal channel set between a picture communication terminal and a wide-band switchboard and attaining transmission/ reception of picture processing signals between terminals or between the terminal and the switchboard in a picture communication mode.
CONSTITUTION: One of two picture communication terminals 1 uses a control signal channel 8 while the communication is performed between both terminals 1 via a picture signal channel 7. Thus the picture processing control signal is transmitted to a picture processing control unit VPC6 for output of a picture processing request. Then the VPC6 gives an indication to the CPU of a wide- band switchboard 4 to give an interruption of the picture signal channel of a picture editing processing unit VPU5 to the channel 7 and obtains a connection state as shown in the diagram. Under such conditions, the VPU5 is connected to the channel 7 of both terminals 1. While both terminals 1 are connected to the VPC6 via the channel 8. Thus it is possible to give picture processing to an optional picture which is under communication between both terminals.

摘要： PURPOSE:To realize miniaturization of a scanning circuit and a line concentrater by using a time switch memory as a memory element and applying large scale circuit integration to a peripheral circuit section. CONSTITUTION:A time switch memory is used for the primary memory 2 and the secondary memory 3 and large scale circuit integration is realized already. Furthermore, the peripheral section 502 includes arrangement conversion, no operation control of the time switch memory and collision protecting means of the primary bus 6 and the secondary bus 7 and is constituted as a circuit possible for LSI. In the constitution above, both the clock and the frame synchronizing signal are fed to the primary memory 2 and the secondary memory 3 while the phase is shifted a half, the data address information required for the operation of each memory supplies input data or receives output data to the primary bus and the secondary bus in time division. As a result, the signal line to the time switch memory from the peripheral section 502 is formed as a bus and the terminal number is not increased in integrating the peripheral section into a large scale.
