Features
This USB-equipped external modem makes connecting to
Asymmetric Digital Subscriber Line (ADSL) services over ordinary
existing phone lines easy—and fast. Supporting up to 8-Mbps
connections, the
External ADSL USB Modem
from Black Box offers
up 160 times faster connectivity than traditional access technologies.
It’s ideal for business or home users who require broadband for
demanding videoconferencing, MP3, and multimedia applications.
The benefits of ADSL enhance your overall Internet and remote access
experience and enable you to work more efficiently. Plus, an ADSL
connection is always on, so you don’t have to wait for a dialup
sequence, as one does with analog modems. And because ADSL
service is offered over an analog phone line (by placing the ADSL
signal above the frequency of the voice signal), you won’t need an
additional line to receive voice calls when you’re on-line. Asymmetric
operation of this sort is ideal for most home or small office setups,
where users are more likely to download files than to upload
information.
The modem operates in Discrete Multi-Tone (DMT Issue 2) based
mode of operation. DMT mode supports ITU G.992.1 (G.DMT) and
G.992.2 (G.lite) along with ANSI standard T1.413 issue 2 and gives
you data rates of up to 8 Mbps receiving and 1 Mbps sending.
OVERVIEW
You can use the
External ADSL USB Modem
with most industry-
standard Digital Subscriber Line Access Multiplexors (DSLAMs) that
operate in DMT mode.
By getting USB technology in an external modem that can handle
DMT communications, you’re given convenience in an easy-to-install
device. You don’t have to remove the lid on your machine, inspect
for IRQ conflicts and face CPU power drains, as you might with an
internal modem card.
And the modem’s splitterless, so you can install it yourself.
Connect the box to the ADSL line via standard RJ-11 connections and
to a PC via a standard USB interface. It comes with Windows
®
based
configuration software, including an installation wizard that guides
you through the configuration process. An easy-to-manage
diagnostics tool even lets you view ADSL connection statistics and
driver information, so you can troubleshoot ADSL link problems.
When the green indicator is on in the Link Status field of the onscreen
Control Panel, you know a modem connection has been made. A
blinking indicator tells you that a connection is being established. The
modem’s transmitting and receiving data activity are shown separately
by individual flashing yellow indicators on the Control Panel.
