摘要： PURPOSE:To improve the information transfer efficiency by selecting a channel in matching with a channel selected for use by a sender side from the standpoint of information transfer capability when a called channel is selected so as to allow the information transfer capability of both channels to enhance completely. CONSTITUTION:A caller channel information transfer means 201 adds identification information of a transmission channel decided for use between a caller terminal equipment 100 and an exchange 200 at setup to a caller request packet and a called terminal equipment 300 transfers the result to a caller exchange 400 accommodating a called terminal equipment 300. When a called channel discrimination means 401 decides a called channel used with the called terminal equipment 300, the identification information of the caller channel transferred from the caller exchange 200 is referenced to decide the called channel satisfying the information transfer capability of the transmission channel. Thus, when the called channel is selected, the channel in matching with the channel selected for use at the caller side from the standpoint of the information transfer capability is selected, the information transfer capability of both channels is completely enhanced and the information transfer efficiency of an integrated services digital network is improved.

摘要： PURPOSE:To greatly shorten the stop time of a data control system by converting old data into new data by the data control system while an old program is executed, and stopping the execution of the old program at the end point of time of the conversion and executing a new program. CONSTITUTION:A main storage device 2 and external storage devices 3-1 and 3-2 are stored with the old program PO that a central processor 1 is executing and the old data DO for executing the program. Then the device 3-2 is stored with the new program PN that the processor 1 is to execute and a data converting means 50 which converts the old data DO into the new data DN. The processor 1 executes the means 50 under the control of the program PO to convert the old data DO into the new data DN and then the new program PN is stored on the device 3-2. The processor 1 stops the execution of the old program PO temporarily, stores the new program PN and new data DN which are already stored on the device 3-2 on the device 2, and starts executing the new program PN. Consequently, the need for an on-line processing system dedicated to the data conversion is eliminated and the stop period of the system is greatly shortened.

摘要： PURPOSE: To reduce burden on call setting processing by multiplexing a call originating request packet and performing connection processing by sending it to the terminal of an incoming call destination by a packet switching machine on an incoming call side receiving the packet. CONSTITUTION: The call originating request packet CR from the terminals A1-An on a call originating side multiplexed by the multiplexing control processing part 160 of the packet switching machine 101. At this time, the processing part 160 multiplexes the packet by referring to a group managing table and a multiplexing managing table provided in a main memory device 120. A multiplexed packet CA is received by the packet switching machine 102 on the incoming call side, and a communication control part 130 performs call setting between the transmission terminals A1-An and the terminal B1 on the incoming call side. Moreover, the switching machine 102 sends out a call setting result to the terminal B1 via a relay line L. The control part 130 receives it, and returns a confirmation packet to the switching machine 102.

摘要： PURPOSE:To shorten the data(DT) packet transfer time by transferring an incoming transfer list from an original called station to a caller station and applying the incoming call transfer processing according to the leadership of the caller station so as to omit useless relay processing by the original called station in the data transfer after the end of call setting. CONSTITUTION:When a caller station (A) 1 transfers a usual caller request(CR) packet to an original called station (B) 2, the original called station (B) 2 sets a called party transfer destination for a subscriber (b) 12 set in a main memory(MM) and incoming call transfer request display to a restoration request (CQ) packet when the arrival of the call to the subscriber (b) 12 is disabled and transfers the result to the caller station (A) 1. The caller station (A) 1 fetches the incoming call transfer destination list for the subscriber (b) 12 set in a restoration request (CQ) packet and applies initial setting to a subscriber selection pointer. Thus, no original called station (B) 2 exists among subscribers (a) 11-(d) 14 connected finally and the data transfer time is reduced.

摘要： PROBLEM TO BE SOLVED: To provide the network system to be installed without revising set contents of an existing PBX network. SOLUTION: A 1st conversion means 27 of a 1st communication equipment 10 converts a data destination address receives from a PBX 51 into a unified address unified in an integrated network TN. Succeedingly, an ATM transmission processing section 29 generates a setup message including the unified address and an ATM exchange processing section 23 sends the setup message to a 2nd communication equipment 12. When the incoming call processing section 30 of the 2nd communication equipment receiving the calling set up message extracts the unified address, a PBX specification means 31 specifies a PBX to which a data destination address is to be given. Then a 2nd conversion means 32 converts the unified address into an original data destination address and the data destination address is sent to a PBX 63 specified by the PBX specification means 31.

摘要： PURPOSE:To prevent the lowering of the communication throughput of a communica tion processor accompanying the gathering processing of log data by letting the commu nication processors of both operating system and standby system perform the gathering processing of the log data. CONSTITUTION:Dual communication processors IA transmit communication data to a transmission line 2 and receive reception data inputted from a reception line 3 in the case of being set to the operating system. Also, the communication processor IA is provided with a log data gathering means 11A for inputting transmission/ reception data and outputting them by a log data gathering instruction and a log data processing means 12A for storing the transmission/reception data outputted by the log data gathering means 11A in a log data storage part 6. A transmission switching part 4 switches the transmission data from the operating system communication processor to the transmission line 2 and a reception switching part 5 switches the reception data so as to be received in the operating system communication processor. When log data gathering is instructed to the communication processor 1A of the standby system, since the communication processor 1A of the standby system performs a log data gathering processing and the communication processor of the throughput of the communication processing is not lowered.
