<p>Method and concentration arrangement which are intended to enable several data terminals, synchronous or asynchronous, (3 to 6) to be served by the same channel B of an ISDN network (2) to which these terminals are linked by a digital subscriber termination (1) and adaptors (7, 8) for packet mode transmissions, the adaptors being connected up to the digital subscriber termination at basic gateway S0 level. In the event of a request for communication via channel B between a first terminal served by a first adaptor and a packet type ISDN gateway (10 or 11), to which a second terminal already has access, via a second adaptor and by way of a first channel B, a link is set up for travel between the two adaptors by way of the digital subscriber terminal by means of a second channel B. The data packets transmitted between the first terminal and the relevant ISDN gateway travel via the adaptor of the second terminal. <IMAGE></p> |
