2.24 — IOLINK-520 & IOLINK-PRO Installation & Applications Guide
2.2.3 - Basic Leased Line Configuration
The IOLINK-520 & IOLINK-PRO establishes PPP (Point to Point Protocol) WAN
connections to other PPP Leased Line IOLINK 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 IOLINK-520 & IOLINK-PRO 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”.

2.2.3.1 - 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 IOLINK router should be configured with a remote site profile entry for that
vendors router.
Before the IOLINK-520 & IOLINK-PRO can establish a link connection to another PPP
router, the link speed information must be defined. Refer to the following diagram that
shows two IOLINK routers and another vendors unit connected together with direct leased
line connections.
