WAN
The parameters are described below:
♦
Description – This is a user-defined, 32-character identifier used to name the WAN.
♦
Modem Init String – This parameter is valid only for asynchronous connections. It is a user input AT
command string to initialize a modem or ISDN TA attached to the WAN interface. Please refer to your WAN
device’s handbook for more information about using initialization command strings.
The default setting is for Hayes-compatible asynchronous modems and is AT&FS0=1X1 , where:
AT– The mandatory first two characters of an AT command string.
&F– Initializes the modem to its default settings.
S0=1– Sets the modem to auto-answer.
X1 – Displays the established connection speed to the dial-in user (e.g. Connection established at 56.6
kps).
♦
Protocol – This is a protocol used to encapsulate IP messages over synchronous and asynchronous serial links.
The device being connected to must be using the same protocol for a connection to succeed. The five protocols
are described:
1. CISCO_HDLC – This is a serial line encapsulation method for transmitting datagrams over synchronous
serial point-to-point links.
2. SLIP – Serial Line Internet Protocol. A serial line encapsulation method for transmitting datagrams over
asynchronous serial point-to-point links. If linking the router to a computer, each end must know the other’s
IP address.
3. PPP_SYN – This serial line encapsulation provides a method for transmitting datagrams over synchronous
serial point-to-point links. Unlike the SLIP protocol, PPP can determine the IP address configuration
automatically.
