Unused: The protocol mapping entry is not used.
Single: For a single entry, the packet is sent to the associated radio address if the protocol address
matches the first address. The last address is ignored. This is a “one-to-one” mapping.
Mapped: For a mapped entry, the mapping is applied if the protocol address is within the range
specified by the first and last addresses. To determine the radio address, the offset from the first
address is added to the associated radio address entry. This is a series of “one-to-one” mappings.
Grouped: For a grouped entry, the packet is sent to the associated radio address if the protocol
address is within the range of the first and last address. This is a “many-to-one” mapping.
An example protocol mapping table is shown in Figure 12.
