Chapter 12 Interfaces The following table describes the labels in this screen. Table 71 Configuration > Network > Interface > Cellular > Add LABEL Show Advance Settings / Hide Advance Settings General Settings Enable Interface Interface Properties Interface Name Zone Extension Slot Connected Device Description Connectivity Nailed-Up Idle timeout ISP Settings Profile Selection DESCRIPTION Click this button to display a greater or lesser number of configuration fields. Select this option to turn on this interface. Select a name for the interface. Select the zone to which you want the cellular interface to belong. The zone determines the security settings the ISG50 uses for the interface. This is the USB slot that you are configuring for use with a 3G card. This displays the manufacturer and model name of your 3G card if you inserted one in the ISG50. Otherwise, it displays none. Enter a description of this interface. It is not used elsewhere. You can use alphanumeric and characters, and it can be up to 60 characters long. Select this if the connection should always be up. Clear this to have the ISG50 to establish the connection only when there is traffic. You might not nail up the connection if there is little traffic through the interface or if it costs money to keep the connection available. This value specifies the time in seconds (0~360) that elapses before the ISG50 automatically disconnects from the ISP's server. Zero disables the idle timeout. Select Device to use one of the 3G device's profiles of device settings. Then select the profile (use Profile 1 unless your ISP instructed you to do otherwise). APN Select Custom to configure your device settings yourself. This field is read-only if you selected Device in the profile selection. Select Custom in the profile selection to be able to manually input the APN (Access Point Name) provided by your service provider. This field applies with a GSM or HSDPA 3G card. Enter the APN from your service provider. Connections with different APNs may provide different services (such as Internet access or MMS (Multi-Media Messaging Service)) and charge method. Dial String You can enter up to 63 ASCII printable characters. Spaces are allowed. Enter the dial string if your ISP provides a string, which would include the APN, to initialize the 3G card. You can enter up to 63 ASCII printable characters. Spaces are allowed. Authentication Type This field is available only when you insert a GSM 3G card. The ISG50 supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is readily available on more platforms. Use the drop-down list box to select an authentication protocol for outgoing calls. Options are: None: No authentication for outgoing calls. CHAP - Your ISG50 accepts CHAP requests only. PAP - Your ISG50 accepts PAP requests only. ISG50 User's Guide 255
