Does the Telephone
Company Need to Be
Involved?
You must rely on the local telephone company to provide one or more
loop-start lines and the telephone number or numbers. If a fax machine
will not connect directly to the NBX system through an Analog Terminal
Adapter, reserve at least one telephone line for the fax machine.
CAUTION:
To avoid damage to any 3Com telephone, do not connect it
directly to a standard telephone line. Although the RJ-11 connector for a
traditional telephone fits into the 3Com telephone’s RJ-45 jack, the
electrical interfaces are not compatible and the telephone will not work.
Can Existing Office
Telephone Wires Be
Reused?
You may be able to reuse the wires if they comply with10BASE-T or
100BASE-T cabling specifications, but you will probably need to replace
the connectors. An Ethernet 10BASE-T or 100BASE-T device requires
eight wires (four pairs) connected to specific pins on RJ-45 connectors, a
task best left to a qualified technician using the proper tools.
If you already have a 10BASE-T or 100BASE-T LAN connecting the
desktops, you can ignore existing telephone wires and connect the 3Com
telephones to the LAN. Each 3Com telephone functions as an Ethernet
hub (1102) or switch (2101 and 2102), allowing you to connect the
computer’s network interface card directly to the phone.
Is Any Additional
Equipment Required?
You may need some of the following components:
■
To configure the NBX system, you need a computer equipped with a
browser, such as Microsoft Internet Explorer Release 5.5 or higher, a
network interface card, and a CD-ROM drive. You also need to
provide IP configuration parameters for the system.
■
Computers that use Computer Telephony Integration (CTI)
applications need an operating system that supports the Microsoft
TAPI 2.X standard, such as Windows 98, Windows XP, Windows 2000,
or Windows NT, and a browser to download the TAPI-related NBX
support software through the NBX NetSet utility.
■
If you choose to install the NBX system in an equipment rack, you
need a standard 486 mm (19 in.) rack.
■
You may need 10BASE-T or 100BASE-T Ethernet cable and connectors
to connect the telephones to the hub. Each telephone includes a
10-foot cable.
■
3Com strongly recommends that you use of surge suppression devices
on all local telephone lines.
