An integrated services digital network terminal device, comprising:

• key input means connected with an ISDN through a basic rate user interface BRI including two B channels, and provided with a plurality of keys for inputting either of called party addresses and called party addresses and corresponding called party subaddresses;
• communication control means for controlling connection of the two B channels with a called communication terminal device;
• key input control means for directing said communication control means to connect each of said B channels with said called communication terminal device at either of the called party addresses and the called party addresses and the corresponding called party subaddresses which is a key input series input from said key input means;
• and
• means for making communication with the called terminal device simultaneously using the two B channels connected thereto,
• wherein said key input means includes a pausing key for inputting a pause between the called party numbers, and
• further wherein when any input of said pausing key is included in the key input series input from the said key input means, said key input control means directs said communication control means to connect the first B channel with the called communication terminal at either of a first called party address and a first called party address and a corresponding first called party subaddress which is the key input series input before said pausing key is input, and directs said communication control means to connect the second B channel with the called communication terminal at either of a second called party address and a second called party address and a corresponding second called party subaddress which is either of the first called party address and the first called party address and corresponding first called party subaddress, respectively, modified on the basis of the key input series inputted after said pausing key is input, and
• wherein even further, when no input of said pausing key is included in the key input series input from said key input means, said key input control means directs said communication control means to connect the first and second B channels with the called communication terminal at either of the called party address and the called party address and corresponding called party subaddress which is the key input series input.
