Sample Network Topology

Sample Network Topology

Introduction	Figure 1-2shows a sample network topology for the Vanguard 650 Series. This
	example, depicting a State Lottery network, shows the connection for the DMS-100
	ISDN switch. The example assumes that the Lottery Terminal has a 202T four-wire
	interface communicating at 1800 or 2400 bps. If the interface required is V.24, then
	you would configure Port 3 and set the soft switch parameter in the Node Record to a
	value of NONE.
		Note
		Note that the remote 650D does not initiate calls in this example.
