The PSAX 4500 As a
TCP Client/Server for
the Connection
Gateway API
If you are using the Connection Gateway API with your PSAX system, you
need to configure the system as either a TCP client device or a TCP server
device. If you set up the PSAX system as a TCP client device, you can connect
multiple PSAX systems as TCP client devices to a call controller, which is set
up as a TCP server device (see Figure 3-3).
You can also set up the PSAX system as a TCP server device with the call con-
troller set up as the client device. As an option, you can connect two call con-
trollers, set up as primary and backup client devices, to the PSAX system
(server device) (see Figure 3-4).
