Abstract

The present invention provides a lock out subscriber at a switch suitable for processing a line lock out subscriber that allows the subscriber to return from the line lock out state to a normal state more quickly in order to supplement the processing method for the line lock out subscriber. In the related art, in the case of a conventionally placed telephone, even if the telephone receiver / receiver terminal is locked out, a telephone that is misplaced becomes unreceivable due to a common mistake that is excessive. In the present invention, when the incoming call request is made to the line lockout subscriber, the caller is not informed of the busy tone and the guide is not busy. Clearly show that the line is locked out At the same time, by connecting a Howler tone to a line lock out subscriber, the probability of recovering to a normal state than when provided every 30 minutes can be improved, thereby improving the above-described drawbacks.

Description

How to handle lockout subscribers in exchange

The present invention relates to a method for processing a lock out subscriber at an exchange, and more particularly, to allow a subscriber to return from a line lock out state to a normal state more quickly in order to supplement the processing method for a line lock out subscriber. The present invention relates to a lockout subscriber processing method at an exchange.

After the lockout, a dialing tone of about 10 seconds is sent to the phone.

Next to the dialing tone, a short broadcast of about 40 seconds in English and Korean will be transmitted alternately. After the announcement, a loud hawler tone will be emitted for about 60 seconds.

After a loud howling tone, there is no sound signal.

However, one embodiment of the prior art is a telephone that is placed incorrectly even after the transmission and reception terminal of the telephone is locked out. Another problem is that telephone stations cannot send or receive various data.

The present invention has been made to solve the above-mentioned drawbacks of the prior art, and when a call is requested to a current line lock out subscriber, it is difficult for the calling subscriber to distinguish whether the subscriber is in a line lock out state or a busy state.

Therefore, an object of the present invention is to provide a method for processing a lockout subscriber at an exchange that distinguishes whether a corresponding subscriber is in a call or a line lockout state and helps the line lockout subscriber to recover more quickly.

In order to achieve the above object, the present invention provides a subscriber control unit for translating a call received from a subscriber and controlling connection / disconnection of the call with the translated information, an originating subscriber control unit for processing a call received within the subscriber control unit; A switching system comprising a called subscriber control unit for receiving and receiving a number of called subscribers in a call received from an outgoing subscriber controller in a subscriber control unit, comprising: causing the calling subscriber to hook off to find the called subscriber; When the called subscriber is determined to be in the line lock out state, the step of requesting an incoming call to the called subscriber control unit, determining whether the called subscriber is in the line lock out state by searching for the called subscriber and determining that the called subscriber is in the line lock out state, Accessing the announcement broadcast; Lock-out state of the called party for providing a lock-out processing method of the subscriber from the exchange, characterized in that it comprises the step of repeatedly transmitting the feedback tone.

120: called subscriber control unit

The above and other objects and various advantages of the present invention will become more apparent from the preferred embodiments of the invention described below with reference to the accompanying drawings.

The present invention provides a subscriber control unit 100 for translating a call received from a subscriber and controlling connection / disconnection of a call with the translated information, and an originating subscriber control unit for processing a call received in the subscriber control unit 100. 110 and the called subscriber control unit 120 for receiving and processing the incoming subscriber's number in the call received by the calling subscriber control unit 110 in the subscriber control unit 100.

Referring to Fig. 1, the schematic block diagram of a switch suitable for processing a lock-out subscriber at a switch will be described in detail. The subscriber controller 100 receives a call through a line in the case of a local call, and receives the caller. Transmit to the terminal 120 to process the incoming call, or, in the case of a foreign call, receive a relay line, translate the received call number, transmit the translated information to the corresponding subscriber line, and various signal hook flashes received from the subscriber. It recognizes the digit, hook-on, hook-off, etc. to control the subscriber by recognizing the connection / disconnection of the corresponding call of the subscriber.

The originating subscriber controller 110 transmits the call received from the subscriber controller 100 to the number translation block (not shown) and requests a number translation.

The called subscriber control unit 120 receives the number of the called subscriber from the signal received from the calling subscriber control unit 110 in the subscriber control unit 100 to find the line occupied by the called subscriber and process the incoming call.

Referring to Fig. 2, the flow chart at the switchboard which describes the steps of processing the lockout subscriber at the switchboard will be described in detail. Find a subscriber (step 202).

The originating subscriber controller 110 requests a call to the called subscriber controller 120 (step 204).

The called subscriber control unit 120 finds the called subscriber and determines whether the called subscriber is in the line lock out state (step 206).

If it is determined in step 206 that the called party is not in the line lock out state, the called party is connected or the busy tone is connected according to the conventional art to notify that the subscriber is busy (step 208).

If it is determined in step 206 that the called party is in the line lock out state, the calling party is connected to the announcement so that the calling party knows that the called party is in the line lockout state (step 210).

The called subscriber who is in the line lock out state repeatedly transmits a howling tone so that the called party hears the howling tone and knows that the telephone is in the wrong position (step 212).

The principles of the invention have been described above in connection with specific devices, which are described by way of example only, and are not limited to the spirit of the invention as described in the appended claims.

As described above, when the incoming call request is made to the line lockout subscriber, the present invention clearly shows that the caller is in the line lockout state, not the busy tone, by notifying the caller not the busy tone. By connecting the Howler Tone to lockout subscribers, it increases the probability of restoring to a normal state than if it had been provided every 30 minutes.

Claims (1)

A subscriber control unit 100 for translating the call received from the subscriber and controlling the connection / disconnection of the call with the translated information, an outgoing subscriber control unit 110 for processing a call received in the subscriber control unit 100, In the switch system including the receiving subscriber control unit 120 to receive and process the incoming subscriber's number in the call received by the originating subscriber control unit 110 in the subscriber control unit 100, Allowing the calling subscriber to hook off to find the called subscriber; Requesting a call to the called subscriber control unit 120; Determining a called subscriber and determining whether the called subscriber is in a line lock out state; Determining that the called subscriber is in the line lock out state by determining in the determining step, and accessing the announcement broadcast to the calling subscriber; And repeatedly transmitting a howling tone to the called subscriber in the line lock out state.
