5. Select ISDN Internet (PPP over ISDN) and ISDN RAS (PPP over ISDN) and 
identify identical dial-up numbers for your ISP using the button Phone 
numbers....
.
6. Close the window by clicking OK.
To establish a multi-link PPP connection in Windows 2000, proceed as follows:
1. Create a new connection to your Internet Service Provider (ISP) in Dial-Up 
Networking or select an already existing connection to your ISP.
2. Select the telephone book entry created in Dial-Up Networking and click the 
Properties button. 
3. From the Basic page, enter ISDN Internet (PPP over ISDN) Modem and the 
virtual modem ISDN RAS (PPP over ISDN) under Dial using.
4. Above the button All devices call the same numbers..., define the same dial-in 
node for the ISP for both virtual modems.
5. Close the window by clicking OK.
Now the system automatically will attempt to connect to the destination ISDN 
number using both ISDN B channels whenever this dial-up connection is 
activated. Which kind of connection actually has been established (PPP or multi-
link PPP) is displayed in the Dial-up icon. Activate the Dial-up icon in the 
Windows NT task bar. Then click the Details button. If the entry PPP multi-link 
is displayed under Frames on the Network Registry page, you are connected to 
the Internet at the maximum transfer rate of 2*64kBit.
Using the Summary page in Dial-up networking, you connect and disconnect the 
second B channel manually as required. This technique allows you to increase the 
transmission capacity to download large files from the Internet and to reduce it 
again afterwards to avoid excessive charges (
Windows NT).
Users of Windows 2000 find these entries on the Details page instead.
Clearing internet connections automatically
Some Internet browsers offer you the option of clearing a connection 
automatically when the connection is idle for a certain amount of time.
To activate this option in the MS Internet Explorer 4.x/5.x, click on Start -> 
Settings -> Control Panel -> Internet -> Connections -> Select modem... -> 
Settings... -> Advanced... -> Disconnect if idle for ... minutes
Faxing with MS Money 98/99 and MS Exchange/Outlook and 
other Fax Group 3 applications (e.g. WinFax PRO 8.x/9.x)
With the virtual modem ISDN FAX (G3) the fax function of MS 
Exchange/Outlook and other Fax Group 3 applications can be used. Fax polling is 
not supported.
