118 CHAPTER 10: CONFIGURING WAN INTERFACE
■ Set the asynchronous serial interface to work in dialup or dedicated line mode
■ Set link layer protocol
■ Set baud rate
■ Set link establishment mode
■ Set the check mode in flow mode
■ Set stop bit in flow mode
■ Set data bit in flow mode
■ Set flow control mode
■ Enable or disable level detection
■ Enable or disable internal loopback and external loopback
■ Set MTU
■ Setting the coding format of Modem
The asynchronous serial interface may also need to be configured with SLIP
parameter, PPP parameter, BDR parameter, IP address, firewall and standby center
parameter as required.
1 Set the synchronous/asynchronous serial interface to work in asynchronous mode
If the physical interface to be configured is synchronous/asynchronous serial
interface, it must be set to work in asynchronous mode by executing the following
commands.
Please use the following command in the view of synchronous / asynchronous
serial interface
Table 94 Set the synchronous/asynchronous serial interface to work in asynchronous
mode
The synchronous/asynchronous serial interface works in synchronous mode by
default.
2 Enter the view of specified asynchronous serial interface
Please use the following commands to enter the view of the specified serial
interface in all views.
Table 95 Enter view of specified asynchronous interface
3 Set the asynchronous serial interface to work in dialup or dedicated line mode.
For special asynchronous serial interface or the asynchronous serial interface set
from synchronous/asynchronous serial interface, it is possible to dialup with
modem
command. Please see Operation Manual - Dial-up for other settings and detailed
Operation Command
