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 be
able to use network resources as if he were connected locally. When
the user dials into the DI-206, the call comes into the D-channel and
after answering the phone, the DI-206:
1. Identifies the Username and Password using the authentication protocol defined in
the Interface Configuration, ISDN submenu. The dial-in user is not prompted
for this information, but must enter it into his dialing software before dialing.
2. Checks the Username and Password against those defined in the Dial-In User
Profiles and Remote Network Profiles.
3. Assuming a matching Dial-In User Profile is found, the router may configure the IP
address of the remote station (as defined in the Dial-In User Profile).
4. Configures a dial-in Interface (a virtual circuit) to handle the connection.
5. Establishes the connection on whichever B-channel (physical port) is open by
mapping the dial-in interface to that port.
