摘要： PURPOSE:To evade useless leasing process by transferring a data between plural branch LANs through a base LAN comprising plural physical or logical transmission lines, and transferring the data in the unit of a fixed length. CONSTITUTION:A base LAN 0 consists of a loop physical transmission line 13 and plural nodes 10 connecting to the line and a branch line LAN 25 at the outside of the base LAN 0 connects to the base LAN 0 via the nodes 10. In general plural stations (terminal equipment) 251 connects to the branch LAN 25. Moreover, a management equipment 211 and a master node are connected by the LAN such as Ethernet 212. Then the management equipment 211 uses the operator command function, that is, a command inputted by the operator to revise the configuration of the base LAN 0 or collect the statistic information in a node. Thus, the useless learning process is avoided.

摘要： PURPOSE:To avoid the waste of lines that reception error is generated due to deficiency in a reception buffer when most of message is sent by allowing each reception station to ensure the reception buffer required for message reception in the initial stage of communication. CONSTITUTION:When a message processed as a capsule is sent while being divided into plural segments 4, a message length display identifier 2 is included in an information field of a FIRST minipacket. Then a reception station being the destination of the minipacket discriminates whether or not an idle buffer required for the reception of all segments exists and whether or not the reception of a message is enabled is informed to an outgoing station via an answer display identifier field. When the reception station can secure a buffer required for the message reception, the minipacket from one and same outgoing station arrived later is received one after another without reaching the rejection of reception due to the deficient buffer.

摘要： PURPOSE:To obtain an initialization system requiring no software change, by assigning peculiar node numbers to respective connection units and by causing each connection unit to transmit this number forward and compare the number transmitted from the back with the transmitted number. CONSTITUTION:Host computers 11-16 are connected through connection units 21-26 by unidirectional loop bus 3 to form a loop bus network system. Peculiar numbers are assigned to respective connection units, and each connection unit not only transmits its own peculiar number forward but also compares the number transmitted from the back with the transmitted number. Only when the number transmitted from the back is larger, this number is transmitted forward to circulate only the maximum number through bus 3. When the maximum number is received by the connection unit which transmitted it, the connection unit transmits the control signal reporting this receiving to bus 3 to set nodes of other connection units to slaves. When the control signal has circuited once through bus 3, the node which transmitted it is set to the master, thus initializing the network system.

摘要： PURPOSE:To attain the acceptance and sending of a mail by placing a mailing device having a mail management function at the center and calling the mailing device from each terminal equipment. CONSTITUTION:An ID card information read means is provided to terminal equipments 2a-2m. When an ID card is inputted at the input of a message, individual identification information recorded on the ID card is used as caller information of the input message and when the ID card is loaded at an output request of the message, the mailing device 6 discriminates the presence of the message based on the personal identification information recorded on the ID information. Then plural messages addressed to a requested person stored in the mailing device 6 are outputted simultaneously to terminal equipments of the request persons. Thus, even when an opposite party is absent or busy, the information is sent without making redialing, and a function of a confidential letter, a registered mail and a confidential registered mail is provided.

摘要： PURPOSE:To improve the transmission efficiency of data information by removing a slot protocol control signal except of a first and a last slots, when the data is transmitted as putting plural slots in a row. CONSTITUTION:When the length of the data to be transmitted is longer than the length of a data area in the single slot of the plural slots, a communication node transmits the data to be transmitted by using the plural slots, as using n-pieces (n is 2 or larger integer) of the continuous slots in a single frame, and in addition, as considering the slot except a first and a n-th slot of the continuous slots to be the signal that the slot protocol control signal is removed from the slot. Thus, when the plural continuous slots are used, the number of bytes, which can be assigned to the data information, is increased, and the slot protocol control signal is extremely lightened, and the transmission efficiency of the data is improved.

摘要： PURPOSE:To form test data by inputting a status transition pattern in which the functional specifications of software are described, forming the functional test cource of the whole system and finding out also an input for generating status transition from the status transition pattern. CONSTITUTION:A test item forming device 2 receives the status transition pattern 1 as input data and outputs test items 3 related to the pattern 1. A test data extracting device 4 receives the test items 3 and outputs test data 5. Stacks 6, 7 are used for the formation of the test items and the extraction of the test data respectively by the test item forming device 2 and the test data extracting device 4. In the status transition pattern 1, 8, 9, 10 show the status, an input from the hardware and an output to the hardware of the status transition respectively. Since the data for a software functional case and test execution can be formed at a high speed in said constitution, the testing efficiency of the software can be sharply improved.
