ISDN Low Layer Compatibility structure
typedef struct isdnLLC
void *dummy; /* ## Q.931 */
The isdnLLC structure for Low Layer Compatibility
provides a means for compatibility checking by an addressed
entity; for example, a remote user, an interworking unit, or a
high-layer function network node addressed by the calling user.
LLC information is transferred transparently by
ISDN between the call originating entity (that is, the
calling user) and the addressed entity. If LLC
negotiation is allowed by the network, the isdnLLC
structure is also passed transparently from the addressed entity
to the originating unit. The isdnLLC structure is
coded according to Q.931.
