TW-H6W1IR ISDN Remote Router
Configuration and Management 49
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.
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 TW-
H6W1IR 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 TW-H6W1IR, the call comes
into the D-channel and after answering the phone, the TW-H6W1IR:
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.
