When the exchange detects an incoming call from the dial-in type analog line, the exchange refers to the memory for a destination corresponding to the received dial-in number, and the fixed destination is defined to the destination ISDN terminal in the dial-in line. Notify the incoming call, including the type of terminal that was set. That is, in the conventional analog line control method of the dial-in system, the type of the calling terminal notified to the destination ISDN terminal is the one fixedly defined for the incoming dial-in line regardless of the dial-in number. Is done.

[0006]

In recent years, with the spread of ISDN, the number of cases where various ISDN terminals are accommodated in PBX extensions has increased. However, except for users who newly introduce lines, PBXs, terminals, etc. For users who want to expand existing equipment, leave the existing analog line on top
In many cases, N lines and ISDN terminals are added and introduced. However, in the conventional dial-in line control method, when an incoming call is received from an analog line, the ISDN
There is a problem that the terminal cannot be operated efficiently. For example, even when the incoming ISDN terminal is a G4 facsimile, ringing occurs due to the ringing tone. If the type of the terminal of the incoming call is a telephone, the ringing tone sounds to prompt a response by the handset, and if the terminal is a facsimile, it does not ring. However, there has been a problem that efficient operation cannot be performed.

The present invention solves the above-mentioned conventional problem. Even if an incoming call is received from an analog line, the ISD
An object of the present invention is to provide an excellent dial-in line control method capable of operating N terminals efficiently.

According to a first aspect of the present invention, a reference dial-in number set in advance and a destination extension corresponding to the reference dial-in number on a one-to-one basis. A memory for storing the number and the terminal type of the calling side is provided. When a received dial-in number is detected from an analog line, a reference dial-in number that matches the received dial-in number is searched from the memory, and the searched reference dial-in number is The corresponding destination extension and calling terminal type are extracted, and the ISDN indicated by the extracted destination extension is extracted.
The terminal is notified of incoming information including the information indicated by the extracted calling terminal type.

The second invention is characterized in that a reference dial-in number consisting of a preset start number and a final number, a destination extension number and a calling terminal corresponding to the reference dial-in number on a one-to-one basis. A memory for storing the type,
When the incoming dial-in number is detected from the analog line,
A reference dial-in number including the received dial-in number within the range of the first number or the last number is searched from the memory, and the difference between the first number of the searched reference dial-in number and the received dial-in number is referred to. The addition extension number is generated by adding the destination extension number corresponding to the dial-in number, and the information indicated by the calling terminal type corresponding to the reference dial-in number searched for to the ISDN terminal indicated by the addition extension number. Notify the incoming information including.

[0010]

Therefore, according to the first aspect of the present invention, the reference dial-in number that matches the received dial-in number is searched, and the ISDN terminal of the destination extension corresponding to the reference dial-in number is sent to the calling side. Since the incoming call information including the terminal type is notified, the ISDN terminal can be operated efficiently when there is a dial-in incoming call from an analog line.

[0011] According to the second invention, a reference dial-in number including the received dial-in number within the range from the first number to the last number is searched, and the call should be received from the reference dial-in number and the first number. The extension number is calculated and generated, and the ISDN terminal of the generated extension number is notified of incoming information including the type of the calling terminal.
The DN terminal can operate efficiently.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The first and second embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a system configuration diagram of an embodiment for realizing the dial-in line control method according to the first invention. In FIG. 1, reference numeral 1 denotes a public network (hereinafter simply referred to as "network"), reference numeral 2 denotes an ISDN line connected to the network 1, and reference numeral 3 denotes a dial-in analog line connected to the network 1. 4 is a PBX and 5 is an IS connected to the PBX 4
A DN terminal line 6 is a G4 facsimile with a receiver as an ISDN terminal.

FIG. 2 is a table of a memory (not shown) in the PBX 4. In this table, a dial-in number to be received (hereinafter referred to as a reference dial-in number) is defined in advance. , A destination extension number and a calling terminal type are defined.

Next, the operation of the configuration shown in FIGS. 1 and 2 will be described with reference to an operation flowchart executed by a CPU (not shown) in the PBX 4 shown in FIG.

First, when an incoming call is detected from the network 1 via the analog line 3 (step S1), preparations are made to receive the subsequently transmitted dial-in number, and when the preparation is completed, the primary response signal is sent to the network. 1 (step S
2). Thereafter, from the network 1, for example, the dial-in number “10”
When "00" is detected (step S3), an item number corresponding to the received dial-in number and the defined reference dial-in number is searched with reference to the table of the memory shown in FIG. 2 (step S4). The ISDN terminal having the destination extension "300" defined in the item number obtained by the search is notified of the incoming call by adding information indicated by the originating terminal type defined in the item number (step S5). ). The information to be added includes “telephone”, which is the calling terminal type,
It edits the call setup message including the transmission capability information element and the higher layer compatibility information element, and notifies the ISDN terminal 6 of the incoming call. In this case, the destination is a G4 facsimile that can be used by telephone, but this reception is a ringing of the handset and does not result in a facsimile response.

The dial-in number from the network 1 is "100
If "1", the IS of extension number "300"
The incoming call is notified to the DN terminal 6. In this case, "G3 facsimile", which is the calling terminal type, is included in the call setting message and notified. The destination is a G4 facsimile that can be used by telephone, but this call is a facsimile automatic response in the G3 mode and does not ring the handset.

When a response from the destination is detected (step S6), a secondary response is sent to the network 1 (step S6).
7). Thereafter, a communication path is formed between the network 1 and the ISDN terminal 6, and the phase shifts to a communication or communication phase (step S8).

Therefore, the incoming call from the dial-in type analog line 3 to the ISDN terminal 6 connected to the extension of the PBX 4 can be efficiently controlled.
