Abstract

PURPOSE:To decide an answering or no-answering state with no charging by transmitting the different call signals in accordance with the degrees of importance of an ISDN digital telephone system terminal set at the outgoing side. CONSTITUTION:The outgoing numbers are registered into an outgoing number registering table. Then an incoming prescribing class is decided to the outgoing side based on a fact whether or not the coincidence is secured between the call setting outgoing numbers and an incoming subaddresses sent from a network via an ISDN digital telephone system terminal 31 set at the outgoing side and the outgoing numbers registered in the outgoing number register tables of the ISDN digital telephone system terminals TE1-TE8 and a subaddress of the incoming side recorded previously. Thus a call signal is transmitted in response to the decided incoming prescribing class. Then it is possible to avoid such a case where the charging is applied regardless of the propriety of calling.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to an ISDN digital telephone terminal, and in particular to an ISDN terminal having a function of assigning an incoming call regulation class to a calling party.
Regarding DN digital telephone terminals.

1 is the calling side, and 31a is the called side. ) has a button Kn (n = 1 to 9 are numbers, n = 10 is *, n = 11 is O, n = 12 is #) as shown in Figure 5, and is made of liquid crystal etc. The calling number is displayed on the display 32.

Note that when the ISDN digital telephone terminals 31 (31a) are bus-wired to the network termination device DSU0, eight ISDN digital telephone terminals 31 are connected to one subscriber line.
(31a) can be connected. An ISDN address consists of a 12-digit ISDN country code (up to 15 digits ISDN international code) consisting of a 1- to 3-digit country code, area code (local and long-distance), and subscriber number, and a subaddress of up to 40 octets. , the calling number is notified to the ISDN digital telephone terminal 31a on the called side in a format guaranteed by the basic layer 3 functions within the network.

When the area code, local code, and subscriber number are sent by operating the button Kn on the ISDN digital telephone terminal 31 having the above configuration, 1 is sent to the ISDN digital telephone terminal 3 on the receiving side.
1a is selected.

There are multiple ISDN digital telephone terminals 31a on the receiving side,
When connected to the network terminating device DSU0, the connected network terminating device DSU calls a plurality of ISDN digital telephone terminals 31a, and the l5 that responded first.
I) Only the N digital telephone terminal 31a is the receiving party.

Note that a subaddress can be assigned to each ISDN digital telephone terminal.

The ISDN digital telephone terminal 31a on the receiving side is equipped with a calling number registration table. When a call is received, when a "Setup message" for call setup is sent from the network to the ISDN digital telephone terminal 31a on the called side, the calling number registered in the calling number registration table is sent to the "Call setup message". Calling Party N
If the caller number does not match the calling number in the information element, "ReleaseComplete" for call release is sent.
Message' back to the network and release the call.

In addition, in the case of a normal analog line, the receiving phone automatically answers after receiving two or three ringing signals, and only when the predetermined PB dial digits are sent and received between the phones, mutual communication is possible. [Problem to be solved by the invention] ISDN digital telephone terminal 31a on the receiving side with the above configuration.
. . . has the disadvantage that if the calling number in the call setting message for call setting does not match the calling number registered in the calling number registration table, the call is released unconditionally.

In addition, in the case of an analog line, the PB dial digits are sent and received after an automatic response, so there is a drawback that charges are incurred regardless of whether the call is successful or not.

[Object of the Invention] The present invention has been made in view of the above-mentioned difficulties, and includes a calling number registration table for registering calling numbers, and a call setting table for setting calls sent from the network via the ISDN digital telephone terminal on the calling side. The calling number and called subaddress are the ISDN of the called party.
By determining the incoming call regulation class for the calling party based on whether or not it matches the calling party number registered in the calling number registration table of the digital telephone terminal and the pre-recorded sub-address of the called party, calls corresponding to the incoming call regulation class can be made. The purpose of the present invention is to provide an ISDN digital telephone terminal capable of calling signals.

[Means for Solving the Problems] The ISDN digital telephone terminal according to the present invention provides a system for receiving a calling party number and a called subaddress for call setup, which are transmitted via a network from an ISDN digital telephone terminal on a calling party. The calling number registration table provided on the ISDN digital telephone terminal, the calling number and called sub-address sent from the ISDN digital telephone terminal on the calling side, and the called sub-address of the ISDN digital telephone terminal on the called side or the calling number registration. Incoming call regulation class determining means that determines the incoming call regulation class for the calling party by comparing the calling number registered in a table; and paging by incoming call regulation class that sends a different paging signal according to the judgment of the incoming call regulation class determination means. This configuration includes a sound sending means.
