ABSTRACT:
A data communications system consists of a number of interconnected nodes forming a frame relay network. A user accesses the network by dialing in via a dial access server (DAS). The DAS-to-frame relay interface supports CCITT Recommundation Q.931 protocols for call control. A data link connection identifier (DLCI) for use in the DAS-to-frame relay network interface is provided in a Q.931 call establishment message.
