JPS61186056A - Pocket bell paging system through private line network - Google Patents

Abstract

PURPOSE:To call a pocket bell belonging to other PBX by using the central control unit of a PBX so as to identify a pocket bell paging call special number sent from the other PBX. CONSTITUTION:When an incoming call comes to a private line trunk TRK, the central control unit CPU complements an incoming register IR to connect the trunk TRK to the register IR so as to receive a dial pulse sent from an opposite station. When the CPU identifies that the sent dial information is the pocket bell paging call special number, an extension number is sent to a pocket bell paging controlling PGC. The controller PGC sends a signal to ring the pocket bell of a called party from an antenna AT.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a pager paging system in an automatic private branch exchange (hereinafter referred to as "PBX").

(Prior Art) Conventional paging services include adding a pager paging device to a PBX and providing the service only within the premises where this device is installed, or using the pager paging service of a public station. It is broadly classified into either.

(Problem to be solved by the invention) The former can only be used from the extension housed in the PBX;
The drawback was that Bocket Per Paging could not be used from outside. The latter uses the public station's pager service, so you can make calls from anywhere via the public station, but on the other hand, there are many inconveniences when using it, as it does not have an automatic answering connection function. If there were many pagers, it would be very expensive.

The purpose of the present invention is to solve the above-mentioned problems by utilizing an existing leased line network that can be used at a much lower cost than a public line, and furthermore, by using automatic pager paging, which was previously possible only within a PBX. The object of the present invention is to provide a pager paging method that also enables response connections.

(Means for Solving the Problems) In order to achieve the above object, the pager paging system via a leased line network according to the present invention connects PBXs to the leased line network, and the central controller of each PBX is connected to other paging systems. If the dial pulse sent from the PBX is a pager paging call special number, it is identified and sent to the calling station, including the pager number of the called party, the area code within the paging operator's dedicated line network, and its extension. a pager paging controller configured to issue an instruction to send a number, store each number and code for paging received by the central controller, and output an activation signal; , each PBX is equipped with a paging device that sends out a signal that causes the called party's pager to ring, and the called party who is paged by the paging device calls the extension telephone of the PBX compatible with the paging device and receives the Shibokerato Bell paging response special number. When the pager number of the called party is dialed, the central controller of the PBX sends the pager number of the called party to the pager paging control unit, and the area code and extension number of the corresponding pager operator. The system is configured to search for the area code and extension number retrieved, and to connect to the calling party based on the retrieved area code and extension number.

(Example) Hereinafter, the present invention will be explained in more detail with reference to the drawings.

1 and 2 are PBX relay system diagrams for explaining an embodiment of the pager paging method according to the present invention, and FIG. 1 shows a pager paging call from another PBX via a dedicated line network. FIG. 2 shows the connection when the called party dials the special number in response to the paging call. In FIG. 1, when there is an incoming call on the leased line trunk TRK, the central control unit CPU captures the empty incoming call register IR, controls the communication path switch SW to connect the leased line trunk TRK to the incoming call register IR, and connects the leased line trunk TRK to the incoming call register IR. Prepare to receive and count dial pulses sent from other automatic private branch exchanges. When the incoming call register R receives the pulses from the other station and counts them to obtain numerical information, this is sent to the central control unit CPU for analysis. When the central control unit CPU identifies that the dial information sent from the destination station is a pager paging call special number, it returns a response signal to the destination station via the leased line trunk TRK, and also sends a response signal to the calling party of the destination station (hereinafter referred to as (referred to as "paging operator")
In response, a message is sent from a voice synthesizer, etc. (not shown), prompting the paging operator to dial the pager number of the called party to be called by pager paging, the area code within the paging operator's dedicated line network, and its extension number. . When the paging operator dials the above number according to the message, the incoming call register IR counts the number and sends it to the central control unit CPU. The central control unit CPU sends the pager number of the called party to be paged by the pager paging received from the incoming call register, the area code within the paging operator's dedicated line network, and its extension number to the pager paging control unit PGC.
, the pager paging controller PGC stores these information in its temporary storage and activates the paging device PG. The paging device PG emits a signal to the antenna AT to ring the pager of the called party to be paged. When the pager paging controller completes these processes, the central controller CPU notifies the paging operator that a paging call has been made by a message from the speech synthesizer and prompts the paging operator to wait for a callback. Thereafter, when the paging operator goes on-hook, the dedicated line that was being used is released.

In the operations and connection processes up to this point, the pager number of the called party dialed by the paging operator, the area code of the paging operator, and its extension number are generally transmitted and received by the switching equipment that manages the leased line network. Due to the problem of uniformity in the number of signal digits, it is necessary to use a PB (button button) signal. 9. The area code mentioned here is the district code within the dedicated line network when a call is made from the PBX to which the called party who was paged belongs to the PBX to which the extension that performed the paging operation belongs.

In Figure 2, when the called party who is paged by paging dials the pager response special number and his/her own pager number from the nearest extension telephone STA, the outgoing call register OR connected to the extension telephone STA dials this number. It is received and sent to the central control unit CPU. Central control unit CPU
sends the pager number dialed by the extension telephone STA to the pager paging controller PGCK. The pager paging control device PGC reads out the area code and extension number of the pocket operator corresponding to the pager number dialed by the extension telephone STA from the memory of several pager calls stored in the temporary storage device; This is sent back to the central controller CPUK. Based on this, the central control unit CPU selects an empty dedicated line trunk T.
Capture the RK and send it the area code and extension number.

The leased line trunk TRK dials them to the opposing station and calls the paging operator's extension.

When the paging operator turns off in response to this call, a conversation between the paging responder and the paging operator becomes possible via the dedicated line network.

(Effects of the Invention) As described above in detail, the present invention allows a pager belonging to another PBX to be called using the pager paging device of that PBX. Another advantage is that if the called party dials a special number and answers, the paging operator can be automatically called.
