Before You Install the
ISDN LAN Modem
To install, configure and use the ISDN LAN Modem successfully, you must have the
following:
■ Correct ISDN service installed at your location with an available ISDN RJ-11 or
RJ-45 outlet. If you have not yet ordered ISDN service, refer to Appendix E.
■ A JavaScript-enabled and frames-capable Web browser. A Web browser is
provided on the 3Com Companion Programs CD-ROM. (For more information
refer to Appendix B.) If you use a different Web browser, make sure that it
supports frames such as Netscape 2.1 and later and Internet Explorer 3.0 and
later.
If you already have a version of the Internet Explorer Web browser installed and
would like to install a later version, you should first uninstall the previous version. If
you are asked to replace the older files, it is recommended that you do so.
■ A personal computer with TCP/IP and Ethernet connectivity that meets UL
standards in the United States or is certified to CSA standards in Canada.
■
For a PC, a 386 or higher processor is recommended and a 10BASE-T
Ethernet card is required.
■
For an Apple Macintosh computer, system 7.6 or later operating system and
Open Transport (provided as part of system 7.5). Built-in Ethernet
connectivity is provided through an Apple Ethernet port in all Power
Macintosh computers.
■
TCP/IP is provided as part of the Windows 98, 95, NT and Macintosh System
7.6 and later operating systems. For Windows 3.11 users, TCP/IP software is
provided on the 3Com Companion Programs CD-ROM.
You do not have to have available storage space on your computer’s hard drive
because nothing is copied as part of the ISDN LAN Modem installation. If you want
to copy any programs or documents from the CD-ROMs, ensure that you have
available hard disk space.
