Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a relay stand paging system in which a switching equipment operator pages (speaker broadcast) an absent extension person to connect him to a trunk of a central office line or the like for the purpose of paging.

Conventionally, when a switching device that has a speaker calling function from a caller responds to an incoming call from an external line such as a central office line and attempts to transfer the call to an extension, if the transferred extension is absent, the incoming station line is temporarily put on hold. , calls the absent extension using the attached speaker calling device, and when the called extension answers on the nearest telephone, a conversation is made with the extension, thereby giving the extension number of the nearest telephone of the absent extension. Upon learning of this, the call was released from hold on the above-mentioned office line and the incoming call was transferred to the above telephone.

This conventional method will be explained using the block diagram of FIG.

In FIG. 1, 5w is a switch configuring the communication path, and M
is the marker, EXT is the extension telephone, BWT is the office line trunk, 0PCT is the operator call trunk, ATT is the relay stand, PO
S is a seat device controlled by the attendant console ATT, PR is a seat register that counts and stores dials from the attendant console ATT, PR is a call register that counts and stores dials from the extension EXT, and PGT has a calling function. It is a paging trunk with. When a call is received from a central office line, a visual and audible display of the incoming office line is made from the central office line trunk BWT to the relay stand ATT, and the operator, knowing that the call has arrived from the central office line, displays the central office line trunk BWT that corresponds to the central office line where the call was received. Press the connection key to make a call to the central office line.

After talking to the central office line, the requested extension number is dialed, and the seat register PR that has counted and accumulated this number is marked M.
The marker M activates the switch SW to establish a communication path between the extension telephone EXT corresponding to the dialed extension number and the office line trunk BWT, and then is restored. As a result of the call with the extension telephone EXT, the operator releases the connection of the switch SW between the office line trunk BWT and the extension telephone EXT if the intended extension party is absent,
Central office line trunk BW where calls were temporarily received due to calls on hold, etc.
After that, the paging trunk PGT is activated by a telephone or the like to perform a speaker call, and the absent person is called by a speaker broadcast. The called party who is called by the speaker broadcast learns of the call from the operator and raises the handset of the nearest extension telephone EXT, and the marker M connects the extension telephone EXT to the outgoing call register 0R through a calling connection. and recover.

After confirming the dial tone from the calling register 0R, the called party dials a predetermined operator calling number. After counting and accumulating this dial, the calling register 0R activates the marker M, and the marker M switches the connection of the extension telephone EXT to the operator call trunk 0PCT from the calling register 0R, and also restores the marker M1 to the calling register 0R. Based on the visible and audible display from the operator call trunk 0PCT, the operator presses the corresponding electric key on the attendant stand ATT to capture the operator call trunk 0PCT, and by talking to the extension person, the above-mentioned person who is the absent extension person is identified. After knowing the number of the extension telephone EXT used by the called party, and instructing the extension person to hang up the handset, the above-mentioned office line can be accessed by pressing the connecting telephone corresponding to the held office line trunk BWT. Re-enter the trunk BWT and dial the above extension number. After counting and accumulating this dial, the seat register PR activates the marker M, and the marker M connects the above-mentioned office line trunk/track BWT and the above-mentioned extension telephone EXT via the switch SW and restores the office line trunk. BW
A ringing signal is sent from T to the extension telephone EXT, and when the called party responds, the handler makes a conversation with the called party, and by pressing the corresponding telephone, the call signal is sent to the telephone number between the central office line and the extension telephone EXT. Complete the connection via line trunk BWT. As explained above, in the conventional system, when a caller uses a speaker paging device to transfer an incoming call to an absent extension, there is a loss of time required to know the extension number of the transferred extension, and There were many operational problems, such as the hassle of duplicating operations due to connection changes.

The present invention was made for the purpose of eliminating such drawbacks, and embodiments of the present invention will be described below with reference to FIGS. 2 and 3.

Note that although FIG. 3 also includes symbols other than those described above, these are elements that are not particularly directly related to the present invention.

First, an embodiment will be explained with reference to FIG.

When an incoming call is received from the central office line, the operator presses the connecting switch corresponding to the central office line trunk BWT where the incoming call is visually and audibly displayed. The line trunk BWT is closed.

That is, the connections A, 口 and C in FIG. 2 are made. After making a call to the central office line, the operator dials the number of an extension telephone, eg, EXT, in order to transfer the call from the central office line to the requested extension.

At this time, the seat register PR is connected to the relay stand ATT via the seat device POS, and the seat register PR counts and accumulates these dials and activates the marker M. The marker M is activated from the seat register PR. A known trunk selection circuit (route 1 shown in Figure 3)
The switch SW of the central office line trunk BWT where the call was received
The level A above was identified, and the level B above the switch SW of the called extension telephone EXT was identified based on the extension number clear report from the seat register PR, and the switch SW was closed to connect the above levels A and B. Rear marker M and seat register P
R will recover. From the central office trunk BWT, there is an extension telephone E.
A calling signal is sent to EXTl, and in response to an extension response, the operator makes a call to extension telephone EXTl via the route EXTl. If the desired extension is not available, the operator should use extension telephone E.
Without disconnecting the connection with XTl and suspending the central office line trunk BWT, in other words, while maintaining the route, relay stand A
By pressing the paging power button of the TT, the connector relay in the paging trunk PGT is activated, thereby connecting the paging trunk PGT and the relay stand ATT.

In other words, the route of the map is closed. Here, a paging broadcast is performed using a speaker calling device connected to the paging trunk PGT. When the corresponding extension person raises the handset of the nearest extension telephone EXT2 in response to this broadcast, the marker M connects the vacant calling register 0R and the extension telephone EXT2 by a known calling connection.

At this time, the marker M transfers the level information C on the switch SW of the extension telephone EXT2 to the calling register 0R,
I will return to Japan. The extension user confirms the dial tone sent from the calling register 0R, and then dials a predetermined number ゜゛X゛ that responds to the paging from the attendant console ATT.

This number "°X" is different from the normal operator call number. The transmission register 0R counts and accumulates the number "X" to identify that it is a paging response, and activates the marker M.

Marker M is activated from transmission register 0R,
The above number "X" has been dialed and the switch S of the extension telephone EXT2 connected to the calling register 0R has been turned on.
It receives the level C information on W, uses the number "X" to identify that the call from extension telephone EXT2 is a paging response, and activates the route relay of the paging trunk PGT. Because the paging trunk PGT is captured by the relay stand ATT and the route relay operates within the paging trunk PGT, a part of the trunk selection circuit of the marker M (1 shown in FIG. 3) is activated.
The ground air sent from marker M via (part of the route of) marker M single line trunk BWT single seat device POS
The route of the paging trunk PGT-marker M returns to the marker M, and the marker M identifies the level A on the switch SW of the central office trunk to which the extension telephone EXT2 is to be connected, that is, the central office trunk BWT where the call was received. The office line trunk BWT and the extension telephone EXT2 are directly connected.

That is, the route of switch S is closed. Seat device PO
In S, the extension telephone EXT2 is connected to the extension side of the central office trunk BWT, so the connection between the relay stand ATT and the paging trunk PGT is maintained by a relay operated by the telephone loop of the extension telephone EXT2. Marker M single line trunk BWT single seat device POS-
The paging trunk PGT-marker M route is restored, and the trunk selection circuit is also disconnected by the relay activated by the telephone loop of the extension telephone EXT2, thereby restoring the marker M, the calling register 0R, and the paging trunk PGT.

The operator speaks to the extension telephone EXT2 via the central office trunk BWT. That is, this state is exactly the same as the state in which an incoming call from the central office line is transferred to the extension telephone EXT2 via the central office trunk BWT.

After talking to the absent extension in this way, the operator operates the relay stand ATT to disconnect from the call between the terminating office line and the extension telephone EXT2. In other words, the main route is disconnected, and the central office line - one central office line trunk BWT - [meth (switch SW) -
Only the route of the Lee extension telephone EXT2 remains.

Note that the routes shown in FIG. 2 are routes necessary for paging, etc. when this switching device is operated in a distributed relay system, and are not directly related to the present invention.

Next, the circuit operation of the main part of the embodiment described above will be explained with reference to FIG.

When the operator presses the paging switch PG on the relay stand ATT to call an absent extension, the paging trunk PGT is activated.
, the connector relay PT operates, and the connector relay PT operates as the relay A of the seat device POS (this relay A is connected to the seat device PO via the switch SW and the office line trunk BWT).
It operates by a telephone loop of extension telephones EXTl or EXT2 connected to S.

) is self-maintained by the battery via the break contact a. Here, when the operator presses the above-mentioned power station PG, the central office line trunk BW
Since no operation is performed to hold T, the connector relay CN that controls the connection between the seat device POS and the central office line trunk BWT remains in operation, and its contact Cn is maintained in the closed state, and the route between them, that is, The oral route shown in FIG. 2 remains closed. By maintaining the operation of the connector relay PT, the paging trunk PGT and the attendant stand ATT are connected, allowing the operator to make a paging call to an absent extension. (the absent extension) answers the paging call at the nearest telephone extension, for example EXT2.

When the called party raises the handset of the extension telephone EXT2, marker M is activated, and the marker M captures the empty call register 0R and transfers the level information C on the switch SW of the extension telephone EXT2 to the call register 0R. However, the marker M is temporarily restored.

Then, when the called party dials the paging response number "X7," the calling register 0R identifies that the response is a paging response and activates the marker M.
As explained in FIG. 2, the level C on the switch SW of the extension telephone EXT2 and the response from the extension telephone EXT2 are identified as paging responses. When the marker M identifies the paging response, the root relay P operates in the paging trunk PGT and its contacts p close.

In the office line trunk BWT, since the office line trunk BWT is captured, the B position relay B is operated, and its contact b is closed.

Further, as described above, the connector relay CN is also operating and its contacts Cn are also closed. Furthermore, in the seat system POS, the link check relay LK is also operating, and its contact 1k is also switched in the opposite direction to that shown in FIG. 3, so the connector relay PT in the paging trunk PGT is operating. Since the contact point Pt is closed and the route relay p is operated and the contact point p is closed, the route shown as 2 in FIG. Trunk BWT (contact c 1 contact b 1 contact Cn) 1 seat device POS (contact a 1 contact
k) - Paging trunk PGT (contact Pt - contact e
One contact d one contact p) - The air sent from the trunk selection circuit of marker M on the route of marker M is returned to marker M via the central office trunk BWT where the call was received.

As a result, the marker M identifies the office line trunk BWT where the above-mentioned incoming call was received, and thereby identifies the accommodation level A on the switch SW. Since the upper accommodation level C is memorized, control is performed to connect the two levels A and C on the switch SW, and the route of the switch is closed at the switch SW.

That is, the central office line trunk BWT that received the call and the extension telephone EXT2 that responded to the paging are directly connected without any connection operation by the operator.

Once the above connection is made, the seat device POS will connect extension telephone E.
Relay A is operated by the telephone loop of XT2, and contact a opens, so that in the paging trunk PGT, the connector relay PT disconnects its holding circuit and recovers, and the capture of the paging trunk PGT is released. The second route is also opened and the marker M is also restored. That is, the paging trunk PGT is automatically released from capture without any operator's intervention when the called party to whom the paging call is made responds. To summarize the attendant paging method according to the present invention from the above explanation, (1) W
In the absence of extension f, the operator performs a paging trunk capture operation.

(Specifically, press the Paging Trunk Capture PG on the Attendant ATT.) (2) At this time, a paging trunk has already been formed between the call trunk and the Attendant in response to the incoming call of the above-mentioned handler. Maintain the connection route without disconnecting it.

(Specifically, keep the connector relay contact Cn of the call trunk BWT closed.) (3) After the handler initiates paging, the called extension's paging response (
Specifically, the called extension dials the special number "X7")
Then, the call trunk portion of the above connection route is extended to the marker via the paging trunk. (Specifically, close the route identification relay contact P of the paging trunk PGT.
)(4) The marker uses the extended connection path to identify the location where the incoming call trunk is accommodated in the call route switch.

(Specifically, by sending earth air to one end of the connection path 2 and detecting the earth air at the other end.) (5) The marker is
A crawler is executed to close the cross point between the accommodation position of the extension telephone that responded to the paging in the communication path switch and the accommodation position of the above-mentioned call trunk in the communication path switch.

(6) By closing the crosspoint, the paging trunk is released from capture.

(Specifically, the paging trunk capture and hold path is cut off by opening the extension side loop monitoring relay contact a of the seat system POS.) Paging connection control is performed in a sequence that passes through each control stage.

As explained above, when making a paging call, the present invention maintains the route connecting the office line trunk BWT and the relay stand ATT as is, and when a paging response is received, the marker M uses the route port. The extension telephone EXT2 that has identified the incoming office line trunk BWT and responded with paging is directly connected to the above-mentioned office line trunk BWT, and the paging trunk PGT that is being captured and the telephone loop of the extension telephone that has responded to the paging and This system is designed to release the capture of the marker M, making it unnecessary for the operator to intervene when the call is transferred to the extension side of the terminating station line, and therefore making the operator's operations extremely simple when making a paging call. The present invention has various advantages, such as greatly shortening the operating time, and has extremely significant effects.

In addition, in the above description of the embodiment, the incoming line is a central office line, and the related central office line trunk is an originating and receiving office line trunk BWT, but the incoming line is not limited to this, and even if it is a dedicated line,
The present invention can also be implemented even if the relevant trunk is a trunk exclusively for incoming calls, for example, and the present invention can also be applied to a paging call based on a request from an extension (in this case, the relevant trunk is a trunk within the local office). It is clear that this can be done.
