The data is configured in units of the connection position NEN of the terminal device. The terminal device number DN as the extension number of the terminal device and the terminal device information as the terminal data are stored as a pair.

For example, in the area indexed by the connection position NEN2a in the terminal device information registration list, the terminal device number DN2a and the terminal device information are stored. still,
The terminal device information corresponds to, for example, data indicating whether or not a call rejection service is being registered.

FIG. 3 is a diagram showing the structure of a duplicate number registration list stored in the storage device 13.

In FIG. 3, the duplicate number registration list is
It is a list for managing the terminal device numbers DN of the terminal devices 2a simultaneously connected to one connection terminal, and the terminal device numbers DN of the terminal devices simultaneously connected to one connection terminal,
The connection position NEN is stored. For example, in the duplicate number registration list, the connection position NEN2a to which the terminal device number DN2a is connected and the terminal device number DN2b of the terminal device 2b connected simultaneously with the terminal device 2a having this terminal device number DN2a are stored as a pair. It is.

Next, a description will be given of a calling operation at the time of an incoming call to a terminal device. FIG. 4 and FIG. 5 are flowcharts showing a calling operation at the time of an incoming call to a terminal device.

In FIG. 4, for example, the terminal equipment number DN2a
Terminal device 2a picks up the receiver (step S1).
0), the central processing unit 12 detects the off-hook, and sends a dial tone to the terminal device 2a having the terminal device number DN2a.

When the terminal equipment 2a hears the dial tone (step S11), the terminal equipment 2a calls the terminal equipment number DN3a of the called terminal equipment 3a to call the extension of the other party.
Is dialed (step S12). Central processing unit 12
Receives the called terminal equipment number DN3a,
3 (step S13), and checks whether the received terminal device number DN3a is registered in the list (step S14). The search is performed sequentially from the top of the duplicate number registration list, and if they do not match, the search of all areas of the list is continued.

If there is no registration in the duplicate number registration list in step S14, the search is terminated, and the terminal device information registration list shown in FIG. 5A is searched for this called terminal device number DN3a (step S18). The terminal device number DN3a is checked in order from the top to see if it is registered in the list (step S19).

If there is no match in step S19, the search of all areas of the list is continued, and if there is no entry in the list, the central processing unit 12 receives the received terminal device number DN3a.
Terminal device 2a that determines that there is no extension
A regulation sound is transmitted to.

In step S19, the central processing unit 12
The terminal device number DN3a received in the terminal device information registration list
If there is, the terminal device connection position NEN3a is read based on the index information matched by the list search (step S20), and the line status such as vacancy / blocking of the terminal device 3a is checked based on the terminal device information (step S20). Step S2
1). If the terminal device 3a is in the closed state, the busy sound is transmitted to the terminal device 2a as the sender.

If it is determined in step S21 that the called terminal device 3a is in an idle state, the status of service registration such as rejection of incoming calls is further checked (step S22). If the service registration during the call rejection is being performed, the terminal device 2a that is the caller
A regulated sound is sent to

If a call can be received at step S22, the central processing unit 12 sends a ringing tone to the terminal equipment 2a as a caller and sends a calling signal to the terminal equipment 3a on the called side. Is sent to be in an incoming call state (step S2).
3).

A normal extension call is processed according to the flow described above. For example, if the called extension has set and registered a call rejection service for rejecting the reception of incoming calls, a missed service or a call forwarding service, In the process of step S21, it is determined that the terminal device is in the closed state, and the call cannot be received by the terminal device dialed by the caller. In this case, conventionally, it has not been possible to connect to the terminal device 3b which has been simultaneously connected to the terminal device 3a.

Therefore, the caller of the terminal device 2a dials the terminal device number DN3b of the terminal device 3b corresponding to the duplex number of the terminal device 3a. Central processing unit 12
Corresponds to the terminal device number registered in the duplicate number registration list in the check processing in step S14, and therefore, the terminal device connection position NEN managed by the duplicate number
3a is read (step S15), terminal device information of the terminal device information registration list is read at the terminal device connection position NEN3a, and based on the terminal device information, the line status such as vacancy / blocking in the terminal device 3b is determined. Check (step S16). If the line state of the terminal device 3b is blocked, a busy tone is transmitted to the terminal device 2a on the caller side.

If the line status of the terminal equipment 3b associated with the called terminal equipment connection position NEN3a is in an idle state, no service check such as rejection of call, absence, transfer of absence, etc. registered in the called party is performed. A ringing tone is sent to the terminal device 2a of the caller, and a calling signal is sent to the terminal device 3a on the called side (step S17), and the terminal device 3b enters an incoming state.

As described above, for example, when the terminal device 3a is a telephone and the terminal device 3b is a facsimile, if a telephone is not connected but a facsimile is to be sent, the terminal device number DN3a of the terminal device 3a as a telephone is dialed. not,
If the terminal device number DN3b of the terminal device 3b as a facsimile is dialed, that is, if the terminal device number of the duplex number is dialed, the facsimile can be called.
