2.2.2.2.124 Fallback

The Fallback key instructs RRAS to communicate at the selected line type but to negotiate a lower quality line type if necessary. This negotiation depends on the condition of the ISDN line (for example, noise on the line affects negotiation). This key is optional. This key is ignored unless the DEVICE key is set to "Isdn". If the key is present, it SHOULD take one of the values given in the following table.
