How the RT-101 Works
The RT-101 gives users across your network access to the
vast resources available on the Internet. Once the RT-101 is
installed and configured, the Internet is just a click away.
The RT-101 is assigned a unique IP addresses that allows it
to communicate directly with the Internet. Activating your
browser and inputting a URL (Universal Resource Locator)
produces a Internet bound data package that is routed
through the RT-101 to Internet. Additionally, since dial up
line fees are dependent on line usage, the RT-101 supports
the following cost saving functions:
IP Spoofing
IP protocol tends to be quite talkative; that is, it is always
requesting and sending RIPs (routing information packets)
to detect any change in resource status-- servers, routers
and other peripheral devices. Spoofing is a means of
filtering the chatter (RIPs) so that when no important data
is present the line can be dropped as defined by the
Disconnect time-out setting. After the line is dropped,
the spoofing mechanism fools the local network into
thinking the line is still up and that the Internet
resources are still available. Without spoofing, the line
would remain up indefinitely and huge line fees would be
incurred.
Dial On Demand
Dial On Demand is an intelligent feature that monitors the

7
dropped communication link for transmission activity. If
activity is detected, a connection with the Internet will
automatically be re-established. To the user, it is as if the
line were never dropped.
