Patent number: 6118863Abstract: A CPU calls in accordance with a MW call-back request one of MW call-back candidates registered in a MW call-back candidate memory region to correspond to a called extension terminal issuing a MW call-back request. When a plurality of MW call-back candidates are registered to correspond to the called terminal, one of the MW call-back candidate terminals which corresponds to one of the count values stored in the count value memory region, which corresponds to the requesting terminal issuing the MW call-back request, is determined as destination terminal. When no response to the MW call-back is obtained, the CPU changes the destination terminal to be called back the next by the same requesting terminal by changing the count values of the MW call-back candidates, which are provided to correspond to the requesting terminal.Type: GrantFiled: September 17, 1997Date of Patent: September 12, 2000Assignee: Kabushiki Kaisha ToshibaInventors: Isaku Komuro, Takashi Aoki

Patent number: 5513256Abstract: A telephone system provided with a key service unit having ports to which terminal telephone sets are connected. The unit has a first memory having memory areas each for storing at least one customer data for each port; a second memory for storing the data temporarily; and a control section for transferring the data between the memory areas through the second memory. The data to be transferred is first transferred from the first memory to the second memory temporarily; secondly data stored in a transfer destination memory area of the first memory (for a port to which a terminal set is newly connected) is transferred to a transfer start memory area of the first memory at which the data to be transferred is originally stored (for a port to which the same terminal set is so far connected); and finally the data already transferred to the second memory is transferred to the transfer destination memory area (as a new port data of the newly reconnected terminal set).Type: GrantFiled: November 17, 1993Date of Patent: April 30, 1996Assignee: Kabushiki Kaisha ToshibaInventor: Isaku Komuro

Patent number: 5224159Abstract: Disclosed is a key telephone system provided with a key service unit (KSU) 1 having a central control unit 6, and a digital key telephone set (DKT) 10 having a local control unit 13 for communications of control data with the central control unit 6. First and second add-on modules (ADMs) 24 and 34 for communications of control data with the central control unit 6 are optionally connectable to the DKT 10. When control data (up-data) are transmitted from the local control unit 13 of the DKT 10 to the KSU 1, a disable signal is given from the DKT 10 to the first ADM 24 to disable up-data from being transmitted from the first ADM 24. At this time, the first ADM 24 also outputs a disable signal to the second ADM 34 to disable up-data from being transmitted from the second ADM 34. At any selected time when no up-data are transmitted from the DKT 10, an enable signal is given from the DKT 10 to the first ADM 24.Type: GrantFiled: January 24, 1992Date of Patent: June 29, 1993Assignee: Kabushiki Kaisha ToshibaInventor: Isaku Komuro

Patent number: 4650932Abstract: In a key telephone system, when it is impossible to set at a time the entire operation data stored in a memory device of a key station unit by using a key of a specific key telephone set among a plurality of key telephone sets connected to the key station unit, the entire data of respective operation items are divided into a plurality of data sets and then the setting of the data of respective data sets are independently set. The division of the data of respective operation items is made corresponding to the output state of a hook switch, for example.Type: GrantFiled: April 3, 1985Date of Patent: March 17, 1987Assignee: Kabushiki Kaisha ToshibaInventors: Isaku Komuro, Yoshikazu Sano

Patent number: 4605825Abstract: In a key telephone system, function assignments are made for assignable-function keys by assigning to each key telephone set one of a number of previously-stored patterns of function assignments. Patterns are stored in a memory of the main unit of the key telephone system. Assignment of functions is thereby done more easily, and efficiency of office line use may be improved.Type: GrantFiled: March 5, 1984Date of Patent: August 12, 1986Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Isaku Komuro, Yoshikazu Sano, Shinichi Shibata

Patent number: 4559417Abstract: A method of setting operating data is provided wherein a display, at a predetermined key telephone set, indicates the capabilities of all sets of the system to perform the various functions of which the system's key telephones are capable. The display indicates three conditions: whether all telephones are capable of performing the indicated function, whether no telephones are capable of performing the function, or whether at least one but not all telephones are so capable. The setting of operating data is facilitated by this display. Changes made in operating data are not permanent until a setting key is depressed. Before that, the original operating data may be recovered.Type: GrantFiled: September 8, 1983Date of Patent: December 17, 1985Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Isaku Komuro, Hideyasu Mori, Yoshikazu Sano
