IOLINK-520 & IOLINK-PRO Installation & Applications Guide —
2.21
Configuration: The default configuration for IOLINK-520 & IOLINK-PRO shipped
outside North America is to have frame relay disabled. To run frame
relay on these routers, it must first be enabled. Selecting the Frame
Relay option will toggle the setting from disabled to enabled.

The router will request confirmation of the change, enter “yes”.
For an IOLINK-520 & IOLINK-PRO with a CSU-DSU interface, the default clock speed
that the IOLINK-520 & IOLINK-PRO will expect to receive from the DCE link is
64Kbps. If the DCE link is 56 Kbps, then the Link Speed value must be reset to 56 here.

2.2.2.1 - Auto Learning the Frame Relay Configuration
The IOLINK-520 & IOLINK-PRO are pre-configured to query the frame relay service
to auto-learn the LMI type and the PVC DLCI numbers. This auto-learn function allows
the IOLINK-520 & IOLINK-PRO to be plugged into the frame relay service and auto-
learn the PVC configuration to become operational without further manual
configuration. IOLINK router auto-learning conforms to RFC1490.
Manual configuration is also allowed by modifying the options within each Remote Site
Profile and the individual link configuration menus.
When the IOLINK-520 or IOLINK-PRO first starts up it will query the frame relay
service to try to determine the LMI type on each of the frame relay links. Once the LMI
type is determined, the PVC configurations will be known from the full status enquiry
messages. If the DLCI numbers of the PVC’s on your service are determined during this
