JPS61134157A - Inter-station callback request transmission system - Google Patents

Abstract

PURPOSE:To simplify a callback operation accurately and quickly by transmitting a signal while its own station information is added, storing the information transmitted from a sender station to a memory at an incoming station, extracting the stored information in the memory and transmitting it to a callback request due to absence of a talking destination. CONSTITUTION:When a subscriber NA1 of a station A makes a call to a subscriber NB11 of a station B, the station A adds the station number of the station A and extension number information of the NA1 to a signal and transmits it to the station B via a sender information transmitter SND2. An incoming information receiver REG17 of the station B receives the information transmitted from the SND2 of the station A, rewrites it on number information of the NB1 and stores the sender station information in a memory corresponding to the said line. If a called party to the subscriber of the NA1 is absent and when a callback is requested to the subscriber of the NB11, the operator of the NB11 applies a special operation and the sender station information stored in the memory is transferred to the storage section corresponding to the subscriber.

Description

[Detailed description of the invention] (Technical field) The present invention relates to an interoffice callback request transmission system.

(Prior art) Conventionally, exchange stations mutually call and call back and send out the information of the corresponding subscriber, and the receiving station uses the information as follows: If there are 9 vacant subscribers, it calls that subscriber and receives the call from the calling station along with the subscriber's response. The call will be between stations. At this time, if the person the calling station subscriber wants to call is absent, etc., he orally requests the calling station subscriber to call back, and the subscriber who receives the request records it in a memo etc. When the line between the stations is restored and the absent person returns, the memo records the receiving station to the originating station, and the number recorded in the memo or the person .

The call was made by dialing a number from memory.

This call-back method has the drawbacks of erroneous connections due to errors in recorded memos or erroneous memories of the person, and time spent searching for telephone directories and the like due to forgetfulness.

(Object of the invention) The object of the present invention is that when a transmitting station sends a call to another station,
The calling station information is automatically added and sent, and the receiving station memorizes the sent calling station information, and when calling back, retrieves the stored information and sends it out. Particularly, it is an object of the present invention to eliminate the above-mentioned drawbacks and to provide an automated and simplified inter-office callback request transmission system.

On the transmitting station side of the system, own station information is added and sent.
At the receiving station 11, the information sent from the originating station is stored in the memory IC, and at the receiving station, the callback information in response to a callback request when the other party is absent, etc. is stored in the memory IC. An inter-office callback request transmission system is obtained that is characterized by extracting and transmitting information.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows a diagram of a relay system between stations in an embodiment of the present invention. A description will be given assuming that station A is the originating station and station B is the terminating station.

In the figure, 1 and 11 are subscribers, 2 and 12 are outgoing information transmitting devices (8ND), and 7 and 17 are incoming information receiving devices (EG).
), 3 and 13 are trunks (TRK), 4.14 are communication path switches (SW), 5.15 are central control units (CC), 6
, 16 is a memory (MM). The transmitting station (A station) and the terminating station (B station) each have a central control unit (CC) 5,15 and a memory (MM) 6.16t, and a transmitting information transmitting device (8ND).
) 2° 12 and an incoming call information receiving device (几EG) 7.17 are provided.

FIG. 2 shows inter-station mutual calling in one embodiment of the present invention.
3 and 4 are processing diagrams at the originating station and the terminating station, in which subscriber (NA) 1 of station A calls subscriber (NB) IIK of station B.

At this time, the transmission information from station A is the normal information (SDM) plus the originating station information (OGM), as shown in Figure 3.
That is, the station number of station A and the extension number information of 8 people 1 are added and sent to 8ND2 as new sending information (8DM'). 8ND2 sends the information to the t-B station.

As shown in FIG. 4, station B receives the information t'' REG17 sent from station A's 8ND2, and stores the received content as received information (BGM').This information is stored in the normal Replace it with the reception information (RGM), that is, the NBII number information, and store the 00M information in the memory (TMA) corresponding to the corresponding line (Figure 2 (a)).
.

At station B, R and GMK perform internal processing in a well-known manner to call NB11, and in response to NB11's response, 5NA1 and NBII become in a communication state (Fig. 2 (off) 0) At this stage, the subscriber of NA1 If the person you want to call is absent, etc., you usually ask the NB11 subscriber to call you back.At this time, the NB11 operator performs special operations (cutting, dialing a special number, etc.).At station B, , the 00M information accumulated in the TMA is transferred to a storage unit (TMB) Ic corresponding to the subscriber.

Once the line has been restored (Fig. 2 (C)), and the person making the request returns, the special operation (seven rings) as shown in Fig. , special number dial, etc.) K2, OG where TMBK is accumulated
M information information 8ND12 is sent to ND12, and the NAI subscriber of station A is called back with the same level of processing as so-called speed dialing.0 The present invention is based on a system with a high signal speed, such as the common line signaling system or the MP signaling system. (Effects of the Invention) As explained above, the present invention has the effect of simplifying, accelerating, and speeding up the call-back operation. There is.

Claims (1)

[Claims] In an exchange system using a storage program control method, the transmitting station adds own station information and sends the information, and the receiving station stores the information sent from the transmitting station in its memory.
An inter-office call-back request transmission method characterized in that the receiving station retrieves and sends information stored in the memory in response to a call-back request when the other party is absent.
