Mode selections

The mode selections for a Point-to-Point Protocol (PPP) connection profile include selections for the connection type and the operating mode. Your mode selections specify how your system uses the new PPP connection.

Follow these steps to specify your mode selections:

1. Select one of the following connection types:

   • Switched line

   • Leased line

   • Layer Two Tunneling Protocol (L2TP) (virtual line)

   • Point-to-Point Protocol over Ethernet (PPPoE) line

2. Select the operating mode that is appropriate for the new PPP connection.

3. Record the connection type and operating mode that you selected. You need this information when you start to configure your PPP connections.

• Switched line
  When you use a modem (internal or external) or an external Integrated Services Digital Network (ISDN) terminal adapter to connect over a telephone line, select the switched line connection.

• Leased line
  If you have a dedicated line between the local system and the remote system, select the leased line connection. If you have a leased line, you do not need a modem or an Integrated Services Digital Network (ISDN) terminal adapter to connect the two systems.

• L2TP (virtual line)
  If you want to provide a connection between systems that use Layer Two Tunneling Protocol (L2TP), select the L2TP connection.

• PPPoE line
  Point-to-Point Protocol over Ethernet (PPPoE) connections use a virtual line to send PPP data (through an Ethernet adapter) to a Digital Subscriber Line (DSL) modem that is provided by your Internet service provider (ISP). The modem is also connected to the Ethernet-based LAN.
