Provides network operators with the information necessary to ensure that Frame Relay data traffic can be routed effectively and efficiently across the International Public Data Network. Also provides guidelines and general principles for the planning of Public Frame Relay Data networks and the routing of International Frame Relay Traffic; guidance on the incorporation of service requirements into the network routing process; and principles for routing in the case of Frame Relay/ATM interworking.
