Installation Questions 83 After the initial installation, the local administrator should be able to install additional telephones and manage the system. 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. A fax machine can connect to the NBX system through an Analog Terminal Adapter. 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. 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 and a network interface card. You also need to provide IP configuration parameters for the system. ■ 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. ■ 3Com strongly recommends that you use surge suppression devices on all local telephone lines. ■ 3Com telephones and attendant consoles that support Power over Ethernet (PoE) do not come with AC power adapters. You can power these devices with any IEEE 802.3af-compliant power source or with optional AC power adapters. The packing sheet that ships with each device shows the device power options. What External Devices Can Connect to an NBX System? The following devices can be connected to an NBX system: ■ Music-on-hold device, such as a radio, tape player, disk player, or computer sound card, equipped with a line out (600 ohm) connection can be connected directly into the NCP to provide audio for callers waiting on hold. ■ Third-party 10BASE-T or 100BASE-T Ethernet hubs and switches. ■ An ISDN (Integrated Services Digital Network) router, Frame Relay Access Device (FRAD) router, or Voice Over IP gateway. ■ A WAN. You can access NBX systems located at branch offices through a wide area network (WAN). Before you use the NBX system

Installation Questions
83
After the initial installation, the local administrator should be able to
install additional telephones and manage the system.
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. A fax machine
can connect to the NBX system through an Analog Terminal Adapter.
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.
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 and a network interface card. You also need to provide IP
configuration parameters for the system.
■
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.
■
3Com strongly recommends that you use surge suppression devices
on all local telephone lines.
■
3Com telephones and attendant consoles that support Power over
Ethernet (PoE) do not come with AC power adapters. You can power
these devices with any IEEE 802.3af-compliant power source or with
optional AC power adapters. The packing sheet that ships with each
device shows the device power options.
What External
Devices Can Connect
to an NBX System?
The following devices can be connected to an NBX system:
■
Music-on-hold device, such as a radio, tape player, disk player, or
computer sound card, equipped with a line out (600 ohm) connection
can be connected directly into the NCP to provide audio for callers
waiting on hold.
■
Third-party 10BASE-T or 100BASE-T Ethernet hubs and switches.
■
An ISDN (Integrated Services Digital Network) router, Frame Relay
Access Device (FRAD) router, or Voice Over IP gateway.
