Configuring a Serial or Voice Port

Before configuring a physical port, make sure that the following have been properly configured:

●Node parameters. See Chapter 4. This is general configuration that must be done no matter which protocols will be run in the node.

●Protocol(s) that will be transmitted over the physical port and any logical ports on the physical port. See Chapter 5.

Once these necessary records have been configured, press [A] (Configuration), then [C] (Configure Ports), then [A] from the Main Menu. When prompted, enter a port number in the range 0–7(noting the port descriptions following Figure 6-1and Figure 6-2).

(Pressing [Enter] without entering a number will accept the default of 0).

Voice ports can also be configured in Voice Application Configuration

([A], [C], [D] from the Main Menu). Also, remember that Voice port 1 is con- figured in the database as port 4, and Voice port 2 is configured as port 5.

The display for an existing record will show the configured parameter values, while the display for a new record will show values stored in a default database record. The following figure is an example of a new record.
