Chapter 4 Configuring the Basic System
Configuring the System for Your Site
Configuring the TCP Client/Server for a Connection Gateway
If you are using the Connection Gateway API with your
PacketStar
AC 60
system, you need to configure the system as either a transmission control
protocol (TCP) client or as a TCP server. If you set up the connection
gateway (CG) device as a TCP server, you can connect multiple AC 60
systems as TCP clients (see Figure 4-10)
You can also set up the AC 60 system as a TCP server with the CG device as
the client. As an option, you can connect two CG devices (clients), set up as
primary and backup CG devices, to the AC 60 system (server) (see
Figure 4-11).
