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
