Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a subscriber line connecting between a group office telephone set and a centrally controlled automatic exchange telephone set at a central office. The present invention relates to a subscriber line switching control method for switching to be used in a time zone. [Prior Art] Night service is provided as a service to a subscriber in a common control type automatic exchange. Night service,
There are discounts on calling charges for subscribers at night, late at night, Sundays and holidays, etc., and they are still widely used by general subscribers. [Problems to be Solved by the Invention] However, the night service conventionally performed is a short time and a period during which the service is performed all day. By the way, in today's rapidly diversified society, for example, subscribers who use this nighttime service do not always have to use a telephone all day, for example, because they are not in one place of their privately owned subscriber telephone but in another place in the daytime. Some subscribers use the telephone only at night without using it. If a new subscriber who wants to use only during the night time zone is newly generated, the common control type automatic exchange side can newly accommodate the subscriber and also use it in a partial time zone. Additional problems arise, such as the power line. On the other hand, in the case of nighttime on the holding and holding line at the office group telephone device side used by each company company,
Unused surplus lines occur due to nighttime aggregation. The current services for such diversified telephone subscribers are not sufficient as detailed services,
Some parts do not conform to the current situation. An object of the present invention is to solve such a problem and to use a redundant line that occurs at night in a business office collective telephone device,
It is an object of the present invention to provide a subscriber line switching control method which can support a subscriber who wants to use a telephone only at night time without adding a new trunk line in terms of quantity. [Means for Solving the Problems] The present invention relates to a subscriber line of a collective office telephone system accommodating a telephone in an office premises or a subscriber who requests outgoing connection only during a predetermined time zone. Line switching control system for connecting a subscriber line to a common control type automatic exchange telephone line device, comprising: sending means for sending a switching control signal by a timer; and Connection means for switching between a subscriber line of the collective telephone apparatus and a subscriber line of a subscriber who requests outgoing connection only during the predetermined time period, and connects to the common control type automatic converter communication path apparatus; It is characterized by having. Embodiment Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the present invention. In this embodiment, a subscriber (SUB) A requesting an outgoing connection from an office such as a company or a company, a subscriber (SUB) B requesting an outgoing connection only during the night time, and a subscription requesting a general outgoing connection (SUB) C. In addition, subscriber A,
B and C respectively represent typical telephone subscribers. The subscriber line switching control system shown in FIG. 1 is based on an office group telephone system (PBX) 4, a switching control unit 1 having a switching control unit 2 and a switching timer unit 3, and a common control type automatic exchange telephone line. Equipment (LINK: hereinafter referred to as exchange communication path equipment) 5
And a central processing unit (CP) 6. In the subscriber line switching control system having such a configuration, the office group telephone apparatus 4 is used in offices such as a company and a company, and accommodates a subscriber A of a telephone in the office premises. The switching timer unit 3 of the switching control device 1 sends a switching control signal to the switching control unit 2 using a timer. The switching control unit 2 of the switching control device 1 includes a switch (S) 2A
have. Further, the switching control unit 2 includes a subscribed oblique line 11 from the office collective telephone device 4 side and an exchange line device 5 of the office.
The subscriber line 12 is connected to the subscriber line 13 of the subscriber B who requests outgoing connection only during a predetermined night time zone. The switch 2A switches and connects these added diagonal lines 11, 12, and 13 in accordance with a switching control signal from the switching timer unit 3. That is, the switch 2A connects the subscriber line 11 from the office collective telephone apparatus 4 side to the subscriber line 12 from the switching line apparatus 5 side of the office in the daytime. Then, only in a predetermined night time zone, the switch 2A connects the subscriber line 13 of the subscriber B to the subscriber line 12 from the switching communication line device 5 side of the office. The switching line device 5 includes a subscriber A connected via the business office collective telephone device 4 and the switching control device 1, a subscriber B connected via the switching control device 1, and a subscriber C directly connected.
It performs connection control and the like in response to an outgoing connection request from. The central processing unit 5 controls information such as subscriber identification, registration, charging, connection control, and the like for the switching communication path device 5. Next, the operation of the present embodiment will be described. In the daytime, the switch 2A of the switching control unit 2 connects the subscriber line 11 from the office collective telephone apparatus 4 side to the subscriber line 12 from the exchange communication path apparatus 5 side of the office. As a result, a group telephone line connected to the office and connected to the office collective telephone apparatus 4 is formed, and in the daytime, the subscriber A in the office premises can make an outgoing connection request to the office. In the night time zone, the holding line on the side of the business group telephone device 4 formed by the connection between the subscriber lines 11 and 12,
The surplus line will not be used due to nighttime aggregation. By the way, the subscriber B who requests outgoing connection only in the night time zone is registered in advance, and the subscriber line 13 of this subscriber B is registered.
Is switched to the above-mentioned surplus line, the following control is performed. The switching timer unit 3 sends a switching control signal to the switching control unit 2 using a timer. The switching control unit 2
The switch 2A is controlled by the switching control signal to connect the subscriber line 11 on the office collective telephone apparatus 4 side to the subscriber line 12 on the switching communication path apparatus 5 side, and to connect to the subscriber line 13 of the subscriber B. The connection is switched to the connection with the subscriber line 12 on the switching communication line apparatus 5 side. As a result, the subscriber B can make an outgoing connection request only during a predetermined nighttime period. As described above, in the present embodiment, the subscriber B who requests outgoing connection only in the night time zone is registered in advance, and a switching control signal is transmitted by the timer in order to switch the subscriber. Is set so that the changeover switch can perform the switching operation on the surplus line. As a result, the subscriber B can make a call request to the station during a predetermined night time zone. [Effects of the Invention] As described above, the present invention makes it possible to effectively use surplus lines that are not used due to nighttime aggregation etc. in the case of night at the holding line at the office group telephone device side used by each company company. By using the service, the company company can preferentially use it in the daytime, and at night the same effect as the night discount service that is currently being done, it is possible to provide night service to ordinary households who want to use only cheap nighttime is there. Further, according to the present invention, it is possible to provide a detailed service to diversified telephone subscribers such as subscribers who want to use only at night time without adding a new trunk line in terms of physical quantity. .
