Chapter 2 - Quickstart Configuration
7
PPP Configuration
This section covers the settings required for PPP (point-to-point) protocol operation of the DS3 
WAN interface. 
Internal DS3 CSU/DSU Link Configuration
Required for Dedicated Line Operation
This is the only mode of operation supported via the built-in DS3 CSU/DSU.
Set Dedicated connection
Set PPP connection
CV:  Use the Link Configuration: WAN Dialog Box.
TB:  Use configure and then set the Mode and ConnectMode keywords in the Link Config 
WAN 0
 section.
Suggested for Dedicated Line Operation
Dedicated line operation generally does not require additional parameters for operation.
IP Protocol
Required for IP
WAN interfaces which are set for PPP operation do not generally use an IP address.  They are 
set to act as an “unnumbered interface.”  In this mode of operation, there are no required 
settings.
Suggested for IP
These parameters help supply information about the segment that the interface is connected to.  
With this information, routing can take place.  
Set IP RIP 1, IP RIP 2, OSPF (Open Shortest Path First) or BGP (Border Gateway 
Protocol)
Set IP static routes
CV:  Use the TCP/IP Routing: WAN Dialog Box to set RIP, and the IP Static Routing Dialog 
Box (under Global/IP Static Routes) to set static routes.  OSPF and BGP can only be config-
ured using text-based configuration.
TB:  Use configure and set either the RIPVersion keyword or the OSPFEnabled keyword in 
the IP WAN 0 section.  Add static routes and a default router in the IP Static section.
Note: Due to the complexity of BGP, configuration parameters for BGP are not given in this 
Quickstart. For help with BGP configuration parameters, and other configuration questions, 
refer to the Tech Support pages on the Compatible Systems Web site at: 
http://www.compatible.com/.
IPX Protocol
Required for IPX
WAN interfaces which are set for PPP operation do not generally use an IPX address.  They are 
set to act as an “unnumbered interface.”  In this mode of operation, there are no required 
settings.
AppleTalk Protocol
Required for AppleTalk
WAN interfaces which are set for PPP operation do not generally use an AppleTalk address.  
They are set to act as an “unnumbered interface.”  In this mode of operation, there are no 
required settings.
