Abstract
A first terminal makes a call over an ISDN link to a second terminal. Both terminals support a plurality of possible protocols to be used on the ISDN B channel. The calling terminal builds the protocol stack for the desired protocol prior to requesting the call from the network. When it is notified of the B channel selected, it can then attach the already formed protocol stack to the relevant B channel. Similarly, the called terminal starts to build the desired protocol stack immediately on receipt of the call. When the protocol stack is complete, is then accepts the call from the network, and can attach the protocol stack immediately to the relevant B channel.
