4.3.1.15 Menu option "Dial-in"
Dial-in can be performed either via the external or via the internal
modem. It is irrespective of the dial-out.). In other words: The modem
configured for dial-out can also additionally be configured here for dial-
in. It is also possible, however, that both modems wait for incoming
calls simultaneously.
The difference between dial-in and call-back is that in dial-in the dialling
computer establishes a direct telephone connection to the computer.
With call-back, the router recognises that it was dialled, hangs up
immediately and either calls back or calls the Internet provider,
depending on how it was configured in the dial-out (see Section
4.3.1.13).
With the external connection, it can be configured here that not a
modem, but a zero-modem cable has been connected so that a
connection is possible via zero-modem cable.
