DI-206 ISDN Remote Router

Management
6. In the case where the Dial-In User does not need to supply a Username and
Password (Auth Type is set to None in the Interface Configuration submenu)
the remote computer must have its own IP address.
Remote Network Connections
Remote networks are defined as other networks (LANs) that have
WAN connections using a router, Internet server, network modem or
similar device (in this document however, we will assume the remote
device is a router). In almost all cases, a Remote Network Profile
needs to be set up for each network that will connect to the DI-206 via
the ISDN lines. The Remote Network Profiles are necessary for the
router to identify and tailor the connection to the remote network’s
router. Once this is done, a connection between the two routers can be
made and computers on each network can communicate with each
other.
Dial-In Network Connections
A dial-in network connection is very similar to a dial-in user connection.
When the remote router 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.
2. Checks the Username and Password against those defined in the Dial-In User
Profiles and Remote Network Profiles.
3. Assuming a matching Remote Network Profile is found, the router may configure the
IP address of the remote station (as defined in the Remote Network Profile).
4. Configures the specified ISDN Interface (a virtual circuit) using the configuration
parameters defined in the Interface Configuration menu and the Remote Network
Profile 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.
