Configuring Physical Ports 6-3
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 6-1 and 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.
