Link configuration defines the type of line service that your PPP
connection profile uses to establish a connection.
The types of line service depend on the connection type that
you specify.
Single line
Select this line service to define a PPP line that is associated
with an analog modem. This option is also used for leased lines where a modem
is not required. The PPP connection profile always uses the same iSeries™ server
communications port resource.
Line pool
Select this line service to set the PPP connection to use a line
from a line pool. When the PPP connection starts, the iSeries™ server selects an unused line
from the line pool. For dial on-demand profiles, the server does not select
the line until it detects TCP/IP traffic for the remote system.
Multiple-connection profile support
Point-to-point connection profiles that support multiple connections allow you to have one connection profile that handles many digital, analog, or L2TP calls.
