Hereinafter, an embodiment of the present invention for achieving the above object in detail.

1 is a block diagram illustrating an embodiment of an analog / digital subscriber voice mailbox matching device of a private exchange according to the present invention.

According to an embodiment of the analog subscriber voice mailbox matching device of the private exchange according to the present invention, the private exchange system 26 may include an incoming call processor 16 that processes an incoming call from another station or an extension of an extension private subscriber. ) And the call according to the analog subscriber from the incoming call processor 16 to the first subscriber line 20 set therein in the absence of the extension subscriber, and the second subscriber line 22 set therein when the message is confirmed. And an input / output unit 24 for inputting and outputting serial data by detecting a signal of the extension subscriber switching unit 18 and a voice mailbox system 36 connected thereto. And a first subscriber interface 28 for matching the first subscriber line 20 and the called party subscriber voice mailbox 32 set therein, and the second subscriber line 22 and the called party subscriber voice mailbox 32. The second subscriber interface 30 to be combined with the serial data interface for matching the input / output unit 24 and the voice mailbox system 36 so that the input / output unit 24 can input / output serial data with the voice mailbox system 36 ( 34).

The analog subscriber voice mailbox matching device of the private exchange made as described above will be described in detail as follows.

First, the incoming call processor 16 in the private exchange system 26 processes the origination of the incoming call or the extension private subscriber from another station, that is, the digital trunk 10 is the digital subscriber from the other station. The incoming call according to the analog trunk (analog trunk) 12 processes incoming calls according to analog subscribers from other stations, respectively, and the line interface 14 handles outgoing calls from internal private subscribers.

Next, the extension subscriber switching unit 18 connects the call according to the analog subscriber from the incoming call processor 16 to the first subscriber line 20 set therein in the absence of the extension subscriber and is set internally when the message is confirmed. The second subscriber line 22 is connected, and the input / output unit 24 detects the signal of the extension subscriber switching unit 18 and is connected to the serial data interface 34 and the RS232C cable, thereby through the voice mailbox system 36. Input and output serial data.

Subsequently, the first subscriber interface 28 in the voice mailbox system 36 matches the first subscriber line 20 and the called party subscriber voice mailbox 32 set therein, and the second subscriber interface 30 provides a second subscriber interface. Subscriber line 22 and destination subscriber voicemail 32 are matched.

At this time, the first subscriber line 20 and the first subscriber interface 28, the second subscriber line 22 and the second subscriber interface 30 are connected via analog lines, respectively.

According to an embodiment of the digital subscriber voice mailbox matching device of the private exchange according to the present invention, the private exchange system 26 may include an incoming call processor 16 that processes an incoming call from another station or an extension of an extension private subscriber. ) And the call according to the digital subscriber from the incoming call processor 16 are connected to the first subscriber line 20 set therein in the absence of the extension subscriber and the second subscriber line 22 set therein when the message is confirmed. And a subscriber station switching unit (18) connected to each other, and the voice mailbox system (36) includes a first subscriber interface (28) for matching a first subscriber line (20) with a called party subscriber voice mailbox (32) set therein. And a second subscriber interface 30 that matches the second subscriber line 22 and the called party voicemail 32.

At this time, the same reference numerals are used for the names of the same blocks used in the analog subscriber voice mailbox matching device of the private exchange and the digital subscriber voice mailbox matching device of the private exchange.

The digital subscriber voice mailbox matching device of the private exchange will be described in detail as follows.

First, the incoming call processor 16 in the private exchange system 26 processes the incoming call or the call of the extension private subscriber from another station, that is, the digital trunk 10 receives the incoming call according to the digital subscriber from the other station. The analog trunk 12 handles incoming calls according to analog subscribers from other stations, respectively, and the line interface 14 handles outgoing calls from internal private subscribers.

Next, the extension subscriber switching unit 18 connects the call according to the digital subscriber from the incoming call processing unit 16 to the first subscriber line 20 set therein in the absence of the extension subscriber and is set internally upon confirmation of the message. A second subscriber line 22 is connected.

Subsequently, the first subscriber interface 28 in the voice mailbox system 36 matches the first subscriber line 20 and the called party subscriber voice mailbox 32 set therein, and the second subscriber interface 30 provides a second subscriber interface. Subscriber line 22 and destination subscriber voicemail 32 are matched.

At this time, the first subscriber line 20 and the first subscriber interface 28, the second subscriber line 22 and the second subscriber interface 30 are connected via digital lines, respectively.

As described above, the present invention provides an analog / digital subscriber voice by matching the analog / digital subscriber and the voice mailbox so that the analog / digital subscriber of the private exchange can use the voice mailbox provided as an additional service of the private exchange. This makes it easier to use mailboxes.
