Basic Leased Line Configuration
The router establishes PPP (Point to Point Protocol) WAN connections to other PPP
Leased Line routers or to other vendors PPP leased line routers via direct leased line
connections. Either 1 or 2 links may be used to connect to other PPP routers.
Configuration: The default configuration for routers shipped within North American with at
least one non-ISDN interface module, is to have frame relay enabled on that
interface. To run PPP leased line, frame relay must be disabled. Selecting the
Frame Relay option will toggle the setting from enabled to disabled.

The router will request confirmation of the change, enter “yes”.
Quick Start PPP Leased Line Connections
A Quick Start minimal configuration may be used to initially establish a connection to
another vendors PPP router. Once the connection is established and is working properly,
the router should be configured with a remote site profile entry for that vendors router.
Before the router can establish a link connection to another PPP router, the link speed
information must be defined. Refer to the following diagram that shows two routers and
another vendors unit connected together with direct leased line connections.
