Providing dial-up access

7 Providing dial-up access
Your LANCOM Office supports dial-up connections to permit individual com-
puters full access to your network. This service is also known as RAS (Remote
Access Service).
The physical connection is realized via ISDN. An ISDN adapter or ISDN
modem is therefore the only hardware requirement for the PC. PPP is used as
the data transfer protocol. This ensures that all common devices and operat-
ing systems are supported.
A setup wizard handles the configuration of the dial-up connection in the
usual convenient manner.

from differing locations.
