WAN Type:
From the
WAN Type
list, choose the type of Internet connection that is required by
your ISP. After you choose the type, additional fields appear, as required for the
connection. Enter the information for the selected WAN type, as described below.
DHCP:
Dynamic Host Control Protocol, the default option, is often used with cable
modems. Select this option if your ISP did not assign a static IP address to your
account and instead uses DHCP to assign an IP address dynamically. No other
information is required for this selection.
Optionally, you can enter a
Domain Name
, if provided by your ISP.
NOTE
One disadvantage of using a dynamic IP address is that if your IP address changes,
your Unified Communications System and all connected devices will reboot.
Telephone service will be interrupted.
Static IP
Select this option if your ISP provides you with a static IP address. Enter your
static
IP Address
, the
Subnet Mask
, the IP address of the
Default Gateway
, and
the IP address for the
Primary DNS
server.
Optionally, you can enter the IP address for a
Secondary DNS
server and a
Domain Name
, if provided by your ISP.
PPPoE (DSL)
PPPoE is often used with DSL services. Select this option if your ISP uses PPPoE
and the router obtains an IP address by using PPP/IPCP address negotiation.
Enter the
Username
and
Password
for your Internet account. Enter the
Service
Name
if provided by your ISP. Also configure your connection with the
Keep Alive
or
Connect On Demand
option, as described below.
•
Keep Alive:
Choose this option to use Keep Alive messages to keep the
connection permanently open, regardless of the level of Internet activity by
your users.
•
Connect On Demand:
Choose this option to open a connection only when
a user attempts to connect to the Internet. In the
Max Idle Time
field, enter
the number of minutes of inactivity that will cause the connection to be
terminated. This option is recommended if your billing is based on the time
that you are connected.
