Configure serial interfaces
Digi TransPort User Guide 278
Protocol Bindings parameters
Digi routers are soft configurable to allow different protocols to be used on different interfaces.
The process of selecting which protocol will be used on a particular interface is referred to as
binding. So, for example Serial (ASY) port 0 may be used for an ISDN B channel X.25 connection in
which case PAD 0 would be bound to Serial 0 (assuming that PAD 0 is the required PAD). (To
complete this example, it would also be necessary to associate the PAD with a LAPB instance
using the appropriate page). Protocols are bound to serial interfaces using a table with a drop-
down list box for selecting the protocol and a drop-down list for selecting the serial port.
By default, if no specific protocol has been bound to a serial interface, a PPP instance will
automatically be associated with that port. This means that PPP is treated as the default protocol
associated with the serial ports.
Protocol
Select the desired protocol from this drop-down list.
Bound to
Select the desired serial port from this drop-down list.
Add
Click this button to add the binding.
Delete
When a binding has been added, it appears in the table and a Delete button is enabled in the
right-hand column. Click this button to remove the binding. Note that the binding does not
come into force until the Apply button at the bottom of the page has been clicked.
