Abstract
A method and at least one subscriber station utilizes a software package in combination with at least one terminal adapter which links ISDN circuit-switched channels, such as 'B', 'H0', 'H10', 'H11' and the like, into a single logical connection and synchronizes the linked channels in an ISDN system. The station allows a subscriber to dynamically select various bandwidths (i.e. different channels) for data transfer, such as text or graphics. The software package and, preferably, multiple terminal adapters, reside on a personal computer and also permits simultaneous messaging and voice functions between several such subscriber stations. Any number of logical channels can be managed. ISDN data is segmented based on the channel's respective data rates and thereafter simultaneously sent on the channels of the logical connection. ISDN data is consequently transferred at a rate greater than the rate available on any single ISDN channel.
