Abstract
A concentration method and concentrator arrangement enable a plurality of synchronous or asynchronous data terminals to be served by a common B channel of an ISDN to which the data terminals are connected by a digital subscriber termination and terminal adapters for transmission in packet mode. The terminal adapters are connected to the digital subscriber termination at the S0 basic access level. In the event of a request for B channel communication between a first data terminal served by a first terminal adapter and a packet mode ISDN port to which a second data terminal already has access via a second terminal adapter and via a first B channel, a transit connection is established between the two terminal adapters via the digital subscriber termination using a second B channel. Data packets conveyed between the first data terminal and the ISDN port are conveyed via the terminal adapter of the second data terminal.
