It is a block diagram showing an example of a private branch exchange of a 1st embodiment. It is a block diagram showing an example of an exchange system of a 2nd embodiment. It is a block diagram showing an example of a line control unit.

  Hereinafter, embodiments will be described with reference to the drawings. Note that, in the embodiments, the same or equivalent elements are denoted by the same reference numerals, and redundant description will be omitted.

<First embodiment>
FIG. 1 is a block diagram illustrating an example of the private branch exchange according to the first embodiment. In FIG. 1, the private branch exchange 10 includes an exchange control unit (call control module) 11, slots 12-1 to 12-N (N is a natural number of 2 or more), a storage unit 13, and a communication bus (first communication bus). L1 and a communication bus (second communication bus) L2. In the following, when the slots 12-1 to 12-N are not distinguished from each other, the slots 12-1 to 12-N may be simply referred to as a slot 12.

  The slots 12-1 to 12-N are arranged in parallel with each other. The slot 12 is configured to accommodate a line control unit (line control circuit) 15. For example, the slot 12 has a terminal 12A and a terminal 12B connected to the line control unit 15 when the line control unit 15 is accommodated.

  An exchange control unit (call control module) 11 controls a line control unit 15 accommodated in a slot 12. Here, the line control unit 15 controls the connection between the first communication device and the second communication device that perform communication in a state where the connection is accommodated in the slot 12. The first communication device and the second communication device may be, for example, an extension terminal or an outside line terminal. That is, the line control unit 15 can perform connection control between, for example, an extension terminal and an office line while being accommodated in the slot 12.

  The communication bus (first communication bus) L1 is connected to the terminal 12A of the slot 12, and connects the line control unit 15 accommodated in the slot 12 to the exchange control unit 11. As a result, the exchange control unit 11 can control the line control unit 15 accommodated in the slot 12.

  The storage unit 13 stores setting information (config information) for the line control unit 15. The storage unit 13 is connected to a communication bus (second communication bus) L2.

  The communication bus (second communication bus) L2 is connected to the terminal 12B, and connects the line control unit 15 accommodated in the slot 12 to the storage unit 13. Thus, the line control unit 15 accommodated in the slot 12 can acquire the setting information from the storage unit 13. Here, the communication bus (second communication bus) L2 is independent of the communication bus (first communication bus) L1. As a result, the line control unit 15 accommodated in the slot 12 can acquire and update the setting information without affecting the call processing by the exchange control unit (call control module) 11.

<Second embodiment>
The second embodiment relates to a more specific embodiment.

<Configuration example of private branch exchange>
FIG. 2 is a block diagram illustrating an example of the switching system according to the second embodiment. In FIG. 2, the switching system 1 has a private branch exchange 20 and a data input device 30.

  The private branch exchange 20 has an acquisition unit 21.

  The acquisition unit 21 acquires setting information from the data input device 30. The acquisition unit 21 and the data input device 30 are connected by wireless or wired. Further, the acquisition unit 21 is connected to the communication bus L2. Then, the acquisition unit 21 causes the storage unit 13 to store the acquired setting information via the communication bus L2. Thus, the private branch exchange 20 can acquire the setting information from the data input device 30 and store it in the storage unit 13 without using the communication bus L1. Here, the communication bus L2 is a communication bus dedicated to transmitting setting information.

<Configuration example of line control unit>
FIG. 3 is a block diagram illustrating an example of the line control unit. FIG. 3 shows a state where the line control unit 15 is accommodated in the slot 12.

  The line control unit 15 housed in the slot 12 acquires the setting information from the storage unit 13 via the communication bus L2 when the line control unit 15 is housed in the slot 12 during operation of the private branch exchange 20, and acquires the acquired setting. An initialization process is performed using the information.

  For example, as shown in FIG. 3, the line control unit 15 has a unit control unit 15A and a unit memory 15B.

  The unit control unit 15A acquires setting information from the storage unit 13 via the communication bus L2 when the line control unit 15 is accommodated in the slot 12 during operation of the private branch exchange 20, and stores the acquired setting information in the unit. It is stored in the memory 15B. The unit memory 15B is, for example, a nonvolatile memory. Then, the unit control unit 15A reads the setting information stored in the unit memory 15B and executes the initialization processing. The setting information includes information on condition settings necessary for the operation of the line control unit 15.

  Further, the unit control unit 15A controls communication with the exchange control unit 11 via the communication bus L1.

  Here, the unit memory 15B may store an initial value (default value) of the setting information set in advance. If the setting information is not stored in the storage unit 13, the unit control unit 15A activates the line control unit 15 based on the initial value (default value) of the setting information stored in the unit memory 15B. Is also good.

  As described above, according to the second embodiment, when the line control unit 15 in the private branch exchange 20 is accommodated in the slot 12, the line control unit 15 acquires the setting information from the storage unit 13 via the communication bus L2 and acquires the setting information. An initialization process is performed using the setting information. Thereby, the line control unit 15 can access the storage unit 13 at the time of startup and automatically obtain the setting information.
