Dial-in
This Chapter explains how to use the RAS Dial-in facility available on the WBR-1100TX LevelOne Wireless Broadband Router.
Overview
To use the RAS Dial-in facility on the WBR-1100TX LevelOne Wireless Broadband
Router, an analog modem or ISDN TA must be connected to the Serial port.
- Each Dial-in user should have a separate log-in and password. Each person
requiring dial-in access is entered in the LevelOne Wireless Broadband Router 's
user database, using the Dial-in Users screen.
- The dial-in user can use their Dial-up Networking software, as used
for Internet access, to connect to the LevelOne Wireless Broadband Router.
- Once connected, the Dial-in user can access TCP/IP-based resources, such as
a Web Server, FTP Sever, E-mail Server, … (Microsoft networking services
are not available.)
- The Dial-in user can also access the Internet via the LevelOne Wireless
Broadband Router 's WAN port.

This chapter is applicable to the LevelOne WBR-1100TX only. |

- 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.

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:
- An Analog Modem or ISDN TA must be connected to the Serial Port on the
LevelOne Wireless Broadband Router.
- The LevelOne Wireless Broadband Router 's Dial-in screen must
be configured for Dial-in access, and Dial-in Users must be created. See
Chapter 7 - Dial-in for details.
- A suitable Dial-up connection must be created on your PC, as described
below.
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:
- Ensure your modem is installed and working.
- Select My Computer, then Dial-up Networking.
- Click Make new Connection, and step through the Wizard.
- Give this connection a suitable name.
- Enter the area code and telephone number to connect to the LevelOne Wireless
Broadband Router.
- Continue the Wizard until completed.
- 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:
- In the Dial-up Networking window, select the connection.
- Right-click, and select Properties to see a screen like the one
below.

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
- In the Dial-up Networking window, double-click the connection to
start the dial-in process.
- 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).
- 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.
- 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.
