The Advanced Functions menu contains most of the more complex configuration
settings and is shown below:
Remote Access Configuration
The Remote Access Configuration menu is used to set up the router for dial-in and
dial-out connections over the ISDN line. An ISDN line has a D channel for
establishing connections and two B (Bearer) channels, which transmit and receive
the actual signals, whether voice or data. The two B channels can support two
independent remote connections or be banded together using Multi-link PPP to
implement Bandwidth on Demand (configured separately in the Multi-Link PPP
Configuration menu, the last item in the Advanced Functions window).
The B-Channels can also carry voice and fax calls, which are routed to the telephone
jacks located on the rear of the router. Please note, however, that the DI-206 can
maintain only two connections at a time via the two B channels, whether the
connections are voice, data, dial-in users, remote networks or a combination thereof.
Remote Operation Overview
The DI-206 is very flexible and can be configured for a variety of remote
connections. Since configuring the router can be quite complex - depending on the
number and type of remote connection(s) you wish to implement – we have
described some of the basic functions and procedures below.
Dial-In User Connections
Dial-in users are defined as a single user on a computer, such as a person working at
home, who dials into the office to use network resources. In almost all cases, a Dial-
In User Profile needs to be set up for each user who will dial in to the router so the
router can tailor the connection for each user. Once this is done, the remote user will
