Dial-in Functionality
When you set up the LAN Modem for dial-in support, you can configure up to ten
designated
Dial-in Users
to dial in to the local LAN. In addition, you must
configure
Dial-in Global Parameters
which apply to all dial-in calls.
When you configure Dial-in Global Parameters, you choose whether to allow one
or both channels to be used for dial-in calls. In addition, you choose whether to
set up all dial-in connections as single channel calls or Multilink-
enabled calls, and you also set the number of rings before the LAN Modem
answers the incoming data call. Depending upon your choice, the following
typical calling scenarios become possible:
Simultaneous Dial-in
and Dial-out Calls
If you configure the LAN Modem to make only one channel available for dial-in
calls, you can have one dial-in and one dial out call occurring simultaneously, as
shown in Figure 11.
