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.”
Configuring ISDN Line
Parameters
During initial set up, you had the opportunity to enter up to two telephone
numbers for your ISDN line. You can make changes to these telephone numbers
or add a third telephone number for your ISDN line. You may want to add a third
telephone number if you are using Multiple Subscriber Numbering (MSN).
In addition, you can configure Terminal Endpoint Identifiers (TEI) if your telephone
company requires this. By default, TEI is set to automatic meaning your telephone
company automatically assigns a TEI to your ISDN line.
What is MSN?
MSN is a supplementary feature offered by some telephone companies which
provides additional telephone numbers for your ISDN line. With these additional
telephone numbers, you can dedicate a telephone number to each device
attached to the ISDN LAN modem. In the ISDN parameters window, enter the
telephone numbers assigned to your ISDN line. To specify how to route calls using
these telephone numbers, refer to “Changing Call Routing”.
Your ISDN line must support MSN to allow multiple telephone numbers for a
single ISDN line. Check with your telephone company.
What is subaddressing?
Subaddressing is another means of assigning specific numbers to devices attached
to the ISDN LAN modem. You can arbitrarily assign extensions to the ISDN
telephone number to route calls to different devices. Note that the telephone
number and subaddress extension that you configure in the ISDN LAN modem
must precisely match the dial string of the incoming call in order for the call to be
routed properly. For example, if you enter 020 555 1212 in the Telephone number
1 field and then enter *2 in the subaddress field, incoming calls must include all of
these digits (020 555 1212 *2). Otherwise, the call is ignored.
If you are using MSN, you will have a different telephone number in each
telephone number field. If you are using subaddressing, enter the same telephone
number in each telephone number field. The unique number in the subaddress
field is used to route the call to the correct device.
