Changing Your
Password
To change the password you defined as part of the initial setup to restrict access to
the ISDN LAN Modem, do the following.
1
From the ISDN LAN Modem main page, click the
Password
button.
2
Enter your new password in the Password field.
3
Enter your new password in the Password (repeat) field to verify the new
password.
4
Click
Submit
.
Once a password is configured, an automatic protection feature is invoked if the
WebWizard configuration program is open and there is inactivity for at least five
minutes. After 5 minutes of inactivity, you are locked out of the Web Wizard
configuration program. The password must be entered to gain access.
If you forget your password, you can reset the ISDN LAN Modem to the factory
default which allows you to enter a new password. Note that when the ISDN LAN
Modem is restored to the factory default settings, you will lose your configuration
which includes all service provider profiles and ISDN parameters. For instructions,
refer to Chapter 9, “Resetting the ISDN LAN Modem.”
Setting Up Your ISDN
Line Manually
This section describes how to set up your ISDN line manually. During initial setup,
the SPID Wizard will already have configured these parameters for you unless you
aborted the SPID Wizard. If you aborted the SPID Wizard, or if you have to change
your ISDN parameter settings, do the following. Before you set up your ISDN line,
you will need the following information about your ISDN line from your telephone
company.
■
ISDN switch type
■
Telephone number(s) for your ISDN line
■
SPID for each telephone number
Indicate this information in the information sheet shown in Figure 50 for easy
reference.
