AAL
ATM Adaptation Layer. Translates packets of data to
53-byte cells for transmission on the network. The
layers are defined to provide different classes of
service for ATM connections, and to provide a
method of mapping data from a particular class of
service into ATM cells in such a way that the data
can be remapped into its original format at the other
end of an ATM network.
