60 Configuring and Managing the SmartServer
PPP Authentication
for Incoming Calls Select the PPP (Point-to-Point Protocol) authentication type to validate the
identity of a remote client. You have three choices:

None. No PPP authentication is used for incoming calls.

PAP (Point-to-Point Access Protocol). PAP uses unencrypted ASCII
encoding to transmit user names and passwords over the network.
Because PAP is considered insecure, only use it if CHAP is not
available, or if the user name and password that the user submitted to
PAP must be sent to another program without encryption. This is the
default.

CHAP (Challenge Handshake Authentication Protocol). CHAP uses
a three-way handshake to validate a remote client when the
connection is established and may validate it again anytime
afterwards. This is the recommended PAP authentication type.

Configuring Dial-out Connections
You can enable the SmartServer to connect to a TCP/IP network via a dial-out modem connection so
that it can connect to other host devices. To do this, specify the phone number or GPRS service to be
used by your SmartServer’s modem to dial out. To configure the dial-out connections, follow these
steps:
1. In the navigation pane directly under the Dial-in modem icon, click the Dial-Out modem icon.
The properties that you can set depend on whether the SmartServer is using its internal analog
modem or an external GSM modem.
2. If you are using an Internal Analog modem, set the following properties:
Dialing Type Select whether the SmartServer’s modem will dial using touch-tone or
pulse dialing. The default dialing type is Tone.
Dialing Prefix Enter a prefix (maximum 30 digits) if the SmartServer is connected to a
phone system that requires a code to be dialed to reach an outside line. By
default, this field is blank.
Delay After Prefix If you entered a dialing prefix, enter the delay (in seconds) between the
prefix and the phone number being dialed. The default delay is 0 seconds.
You must reboot the SmartServer for changes to this property to take
effect
Dial Tone Waiting Enables the modem to wait for a dial tone before dialing out.
