Optional Configuration Menu Items

In rare cases you may need to change some fields on the Common Configuration Page.
Select pulse dialing if your phone line is still set to the old pulse method of dialing.
Change the modem country code if you are using the router outside USA/Canada so
that modem can recognize the dial tone on the line. A list of country codes can be found
on the web at http://www.katpatuka.org/pub/doc/t.35.html. If your phone line is old
or noisy, it may take a little longer to connect to your ISP. In that case, increase the
Modem Connection Timeout to more than 60 seconds. If call waiting service is available
on your phone line you can set the router to either ignore call waiting during a data
connection (callers get a busy tone) or to drop the data connection and allow the
incoming call.
The page also provides the ability to set 2 additional modem

Optional: Dialin Mode (Disabled by Default)

The router also supports the ability to allow external modems to dial into the router
LAN over the phone line. This feature is useful in case the GAC router is at a remote
unattended site and a user would like to connect to PCs on the remote GAC router
LAN. To configure Dialin, enable Select Yes to enable dialin. The number of rings
before the GAC modem picks up the call can also be changed from the default of 3
rings. After clicking Save & Apply, the router needs to be powered off and then powered
on to enable dialin. Dialin to the GAC router can be performed by using the standards
Windows/Mac Dial up Internet Connection client with the username "root" and
password set to the password for root ("admin" by default). For greater security change

to the router (via WiFi or LAN) and you attempt to access the Internet, the router will
make the dial up connection. Enter the time after which the router should automatically
disconnect the connection in case of no activity (180 seconds is recommended). Setting
