Method for controlling data transmission of an integrated services digital network terminal having a multi-channel data transmission capability
First Claim
1. A method of controlling data transmission of a terminal connected to an integrated services digital network which transmits data to a receiving terminal using a plurality of data channels available in the network, said method comprising the steps of:
- transmitting a procedural message from a first terminal to the network so that the procedural message is sent from the network to a second terminal, said procedural message including user-user data in which a channel setup request item is set to a unique first value and a requested channel number item is set to a unique second value;
receiving a connection message at the first terminal from th second terminal via the network in response to the procedural message transmitted by the first terminal, said connection message including user-user data which indicates whether the second terminal accepts the channel setup request and requested channel number from the first terminal, the sending of this connection message from the second terminal to the first terminal establishing a first channel for transmuting information between the first and second terminals;
wherein said transmitting of the procedural message and said receiving of the connection message are repeated until all the data channels indicated by the requested channel number item of the user-user data are established; and
transmitting data from the first terminal to the second terminal through the network by simultaneously using the thus determined number of the data channels.

Abstract
A method of controlling a data transmission from a sending terminal to a receiving terminal through a plurality of data channels in an integrated services digital network. The method includes steps of sending a procedural message from the first terminal to the second terminal via the network, sending, in response to the procedural message, a connection message from the second terminal back to the first terminal via the network, the connection message including user-user data in which a request data is set to a second value, determining the number of the data channels used simultaneously for the data transmission in response to the connection message, received by the first terminal, in which the second value of the request data is equal to a predetermined value, and performing the data transmission from the first terminal to the second terminal by using the determined number of the data channels simultaneously.
