Abstract

PURPOSE:To attain the effective operation of an ISDN line in a common application state of a switchboard to various services that use the number of a subscriber of the incoming side by using a function which informs the opposite party of the number of the subscriber in accordance with the opposite party. CONSTITUTION:An extension terminal control part 6 receives a tenant number and a calling number from an extension terminal 1. A set data retrieving part 7 receives a request from the part 6 to retrieve the set data. An ISDN trunk line control part 8 receives the number of call subscriber based on the retrieving result of the part 7. Thus the number of the opposite party of communication is set to the number of the subscriber so that the number of the subscriber is reported in accordance with the opposite party of communication.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a switching system, and more particularly to a switching system having a function of notifying a calling party number according to a calling party by associating a calling party number with a calling party number.

[0002]

2. Description of the Related Art Conventional ISDN (Integrated Services)
Degital Network) In an exchange that connects to a public network, it is possible to specify the sender number by selecting "Do not notify caller ID" or "Notify contract number (including dial-in number)" depending on the settings of the switch. However, the caller number was uniquely determined by the ISDN station line used for making a call or the extension used for making a call.

The conventional selection of the sender number will be described below. Table 1 below shows a setting example relating to selection of a caller number and a caller subaddress when making an INS (Information Network System) trunk call. (1) If the caller ID cannot be notified

[0004]

[Table 1]

The item of INS calling number shows the setting of the calling number. When "none" is set as in the example shown in Table 1, INS via this trunk group
In trunk transmission, the caller ID notification is designated as not possible, and the caller ID is not notified to the partner terminal.

(2) In the case of notifying the calling party number without a subaddress

[0007]

[Table 2]

As in the example shown in Table 2, INS calling
When the INS number is set in the number item, the set number is basically notified to the other terminal as the caller number. It is checked whether the caller number notified to the partner terminal is a number (including dial-in number) contracted by the caller in the INS net, and if it is not the correct number, it is converted into a contract number. Therefore, even if the number of another line or the like is set in this setting, that number is not displayed on the partner terminal.

Also, as an exceptional case, when the outgoing extension is set as a DIL destination in the same D channel (INS number table) (in the example, in the case of 2110, 2120, 2130, etc.), each extension number The corresponding INS number is notified as the caller number. For example, when making a call from the extension "2110", "066542002" is notified as the caller number. However, since the check of the correspondence between the extension number and the INS number is performed by distinguishing the daytime / nighttime mode, for example, "2120" is not a DIL destination in nighttime mode and "066542000" set in the trunk group is notified. To be done. Thus, the partner terminal can directly connect to the extension of the former caller by calling the notified number.

[0010]

As described above, in the conventional method of selecting the calling party number of the exchange, the calling party number is uniquely determined by the ISDN line used for the outgoing call or the extension used for the outgoing call. It was impossible to choose freely by. Recently, there have been many examples of services such as "displaying the name of the caller" and "corresponding to the caller" on the called side based on the caller number. For this reason, when sharing one switch with tenants and sharing the call with a common party in each tenant, the IS used in each tenant is used to separate the caller numbers.
Since it was necessary to separate the DN lines, it was not possible to use the lines efficiently. Also, a method of changing the caller ID for each terminal to make a call by making a dial contract has been considered, but in this case, there is a problem that a telephone set that can be used for calling is specified for each person making a call.

The present invention has been made in view of the above circumstances, and has a function of notifying a calling party of a caller number corresponding to the calling party. It is an object of the present invention to provide an exchange that supports various services using the caller ID of the receiving side and enables efficient operation of the ISDN line when the exchange is shared.

[0012]

In order to achieve the above object, the present invention provides (1) an extension terminal control unit notified of a call from an extension terminal and a search for setting data from the extension terminal control unit. A reliable setting data search unit and an ISDN station line control unit that notifies the result of the search by the setting data search unit are provided, and by associating the calling party number and the calling party number (2) The setting data search unit notifies the tenant number in the tenant number table and the extension terminal control unit of the tenant number / calling number originating from the extension terminal. And a comparison means for comparing the calling number in the calling number table with the calling number notified by the extension terminal control unit. A.

[0013]

[Operation] The setting data search unit requested to search for setting data by the extension terminal control unit notified of the call from the extension,
Read the tenant number table and compare the tenant number in the tenant number table with the tenant number notified by the extension terminal control unit. If the tenant numbers match,
The pointer in that record reads the calling number table pointed to. Next, the calling number in the calling number table is compared with the calling number notified by the extension terminal control unit.
If the calling numbers match, the calling number table pointed to by the pointer in the record is read and the calling number is notified to the ISDN central line control unit. In this way, by associating the calling party number with the calling party number, the calling party number according to the calling party is notified, and ISDN during shared use
Achieve efficient line operation.
