Configuration: The default configuration for P1705 & P1730 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 P1705 & P1730 with a CSU-DSU interface, the default clock speed that the P1705 &
P1730 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.

Auto Learning the Frame Relay Configuration
The P1705 & P1730 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 P1705 &
P1730 to be plugged into the frame relay service and auto-learn the PVC configuration to
become operational without further manual configuration. 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 P1730 or P1705 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 learning
process, the router will automatically create a remote site profile for each PVC. The
automatically created remote site profiles will be named “LinkxDLCIyyy” where x is the
physical link number the PVC is on and yyy is the DLCI of the PVC.
