187   A traffic specification consists of the AAL type and separate
193   unsigned char aal;
196   AAL types are:
198   ATM_NO_AAL    AAL not specified
204   ATM_SAAL      signaling AAL
206   The Horizon has support for AAL frame types: 0, 3/4 and 5. However,
207   it does not implement AAL 3/4 SAR and it has a different notion of
