2.2 Description of Hardware
The main functions of the Gateway can be divided into
three categories:
1.Connects to the Internet or to a remote site by using its
RJ-45 WAN port or RS232 serial port.
2.Directly connects to your PC or to a local area network
by using any of the three Fast Ethernet LAN ports or
through the IEEE802.11b wireless interface.
3.Functions as a print server as well.
Access speed to the Internet depends on your service type.
Full-rate ADSL can provide up to 8 Mbps downstream and
640 Kbps upstream. G.lite (or splitterless) ADSL provides
up to 1.5 Mbps downstream and 512 Kbps upstream. Cable
modems can provide up to 36 Mbps downstream and 2
Mbps upstream. ISDN can provide up to 128 Kbps when
using two bearer channels. And PSTN analog connections
can now run up to 56 Kbps. However, you should note that
the actual rate provided by specific service providers may
vary dramatically from those above-mentioned limits.
Although access speed to the Internet is determined by the
modem type connected to your Gateway, data passing
between devices connected to your local area network can
run up to 100 Mbps over the Fast Ethernet ports.
The Gateway includes an LED display on the front panel
for system power and port indications that simplifies instal-
lation and network troubleshooting. It also provides three
RJ-45 LAN ports, one RJ-45 WAN port, one RS232 serial
