Introduction : Dial-in and Callback Access to the OnBoard Appliance

Dial-in and Callback Access to the OnBoard Appliance
The OnBoard appliance administrator can configure dial-in or callback access to the OnBoard appliance using PPP through either an external modem connected to the modem port or to a PC modem, GSM or CDMA card. PC modem and phone cards can also be accessed for logins without PPP from a terminal emulation program.
The following table lists the modem and phone card configuration tasks, with links to where they are documented.
Tasks for Configuring Dial-ins and Installing Modems 
NOTE: Administrators can also configure modems through the cycli utility. See Configuring Dial-ins Using cycli for examples.
Table 4.16 shows the configuration options that apply whether a modem or phone card is being configured through the Web Manager or the cycli utility.
Autodetection means that either type of access (PPP or Login) may be automatically detected. When autodetect is selected in the Web Manager, all the fields for configuring PPP and Login appear on the same screen and must be filled out. When autoppp is set using cycli as the modem access type, then the PPP options should be configured.
OTP/otplogin supports OTP authentication for only login access only to modem or GSM or CDMA PCMCIA cards
