Modem

Modem
  • If using a permanent connection or leased line, select "Permanent Connection (leased line)".
  • If your modem or ISDN TA is in the drop-down list, just select it.
  • If your modem is not in the list, select the appropriate "Standard Modem" entry and test to see if this works.
  • If the "Standard Modem" selection does not work, select "User-defined", then click the Modem Properties button to configure the modem correctly.
Modem Properties Button
  • This button is only operational for the "User-defined" modem type.
  • Click this button to open the Modem Properties screen and allow changing of the modem's properties. See Modem Properties Screen later in this Chapter for details.
Serial Line Speed
Select the speed which is equal to or below the fastest SERIAL line speed (NOT phone line speed) of your modem. Available speeds range from 4.8K to 460.8K (bps).

Dial-in Settings

Enable Dial-in
  • If checked, the serial port is available for dial-in access. Otherwise, any attempt to dial-in will be blocked.
  • If Internet Access is also enabled, Dial-in users may find it difficult to connect because the telephone line is in use. Reducing the Disconnect after Idle Time-out setting for Internet Access to 1 minute may help.
  • Only authorized users can use the Dial-in connection.
  • See the Dial-in section of the User Manual for details on setting up the remote PC to use the Dial-in facility.
Disconnect after Idle Time
  • If checked, the Dial-in connection will be terminated after being idle for the time specified.
  • If not checked, the Dial-in connection will never be terminated.
Dial-in PPP
Link
Select the desired security option for log-in:
  • PAP has widespread support; almost all communications systems support it. This is the default setting, and compatible with the default settings for Dial-up Networking in Windows.
  • CHAP is more secure than PAP; the password is encrypted before transmission. If it is selected, the dial-in clients must also support CHAP in order to connect.
  • MS CHAP is the Microsoft version of CHAP, used on Windows platforms. If all dial-in clients are using Windows 95 or later, you can choose this option.
  • None means no checking is performed.

Warning!

  • you choose "None", no User Name/Password authentication is
  • on dial-in. Anyone can connect; this is a major security risk.

Buttons

Dial-in Users
Click this to open a sub-window which allows you to manage the users who can use the Dial-in feature.
  • By default, the "guest" user is defined, but does NOT have Dial-in permission.
  • If the PPP setting above is set to "None" (not recommended), then it is not necessary to create dial-in users.
  • While it is possible to all users to use the same Username/password for Dial-in, the recommended approach is to create a separate entry for each person who needs Dial-in access.
Connection
Status
Click this to open a sub-window which contains details of the current connection, if any, on the Serial Port. Refer to Connection Status - Serial Port in Chapter 5 for further details.

Client PCs - Using Dial-in

This section describes how to configure your PC to use the LevelOne Wireless Broadband Router 's RAS Dial-in feature.

To use the RAS Dial-in feature of the LevelOne Wireless Broadband Router:

Creating a Dial-in Connection in Windows

You can use the standard Windows Dial-up Networking software normally used for Internet access. The procedure is as follows:

  1. Ensure your modem is installed and working.
  2. Select My Computer, then Dial-up Networking.
  3. Click Make new Connection, and step through the Wizard.
  4. Give this connection a suitable name.
  5. Enter the area code and telephone number to connect to the LevelOne Wireless Broadband Router.
  6. Continue the Wizard until completed.
  7. The default values for this connection will work with the LevelOne Wireless Broadband Router 's default values. If necessary, you can adjust the Properties for the connection:

Figure 43: Dial-up Networking Properties

Dial-up Networking Properties

Log on to network
This setting refers to a logon to a Server on your LAN, not the login to the LevelOne Wireless Broadband Router.
This is checked by default, but is not required, and will cause a minor delay in establishing a connection.
Enable software compression
Normally, this should be checked, but the LevelOne Wireless Broadband Router will function with either Checked or Unchecked.
Required encrypted password
The Unchecked state corresponds to the "PAP" setting on the LevelOne Wireless Broadband Router 's Dial-in screen.
The Checked setting corresponds to the "MSCHAP" setting on the LevelOne Wireless Broadband Router 's Dial-in screen.
Require data encryption
This must NOT be checked.
Network Protocols
NetBEUI and IPX/SPX can be disabled.
TCP/IP Settings
The default settings should not be changed.

 

Using the Dial-in Connection

  1. In the Dial-up Networking window, double-click the connection to start the dial-in process.
  2. When prompted for a user name and password, enter the Name and Password assigned to you (this is done on the LevelOne Wireless Broadband Router 's User Details screen).
  3. If the LevelOne Wireless Broadband Router 's Callback feature is enabled, the connection will then be terminated, and your modem must wait for the incoming call from the LevelOne Wireless Broadband Router 's modem.
  4. Upon connection, the LevelOne Wireless Broadband Router will allocate an IP Address to your PC. To other LAN users and devices, you will appear to be a normal LAN user. However, Microsoft Networking features are not available.
