Configuring PPP Interfaces
When powered on, the ATU-R130 initiates a connection through your DSL line to your ISP.
The point-to-point (PPP) protocol is commonly used between ISPs and their customers to identify
and control various communication properties, including:
? Identifying the type of service the ISP provides to a given customer
? Identifying the customer to the ISP through a username and password login
? Enabling the ISP to assign Internet information to the customer' s computers
Your ISP may or may not use the PPP protocol. Contact your ISP to determine if you will need to
change the default settings in order to connect to their server.
Viewing Your Current PPP Configuration
To view your current PPP setup, log into Configuration Manager, click the WAN tab, and then click
PPP
in the task bar. The PPP Configuration page displays, as shown in Figure 37.
Figure 36. PPP Configuration Page{ XE "PPP Configuration page" }{ XE "Pages:PPP Configuration" }
PPP is configured as a group of software settings associated with the ADSL port. Although the
device has only one physical ADSL port, the ATU-R130 can be defined with more than one group
of PPP settings. Each group of settings is called a PPP interface and is given a name, such as
ppp-0, ppp-1, etc.
You can configure the following settings on the PPP Configuration page:
? Inactivity TimeOut (mins): The time in minutes that must elapse before a PPP
connection times-out due to inactivity.
? Ignore WAN to LAN traffic: When enabled, data traffic traveling in the incoming
direction— from the WAN port to the LAN port— will not count as activity on the WAN port;
i.e., it will not prevent the connection from being terminated if inactive for the specified
time.
