ABSTRACT:
A telecommunication method and equipment in a network in which at least two exchange units are connected between an originating data terminal and a terminating data terminal. A transfer rate selection unit is provided in each exchange unit, for selecting one rate arbitrarily from a plurality of transfer rates. An originating call is accessed by including a plurality of accessible transfer rates in a call setup message from the originating data terminal, and each transfer rate is determined in the transfer rate selection units in the exchange units in view of a free channel in a trunk line, from received transfer rate information. The call setup information is transferred to the terminating data terminal, and is modified, based on the transfer rate data included in the call connect message from the terminating data terminal in response to the call setup message by the transfer rate selection unit in each exchange unit. The originating data terminal is informed of the data, and communication therewith is ultimately established by using the efficient transfer rate.
