§ 3.6.1 Commands and responses
The following commands and responses are used by either the user or the network data link
layer entities and are represented in Q.921/table 5. Each data link connection shall support
the full set of commands and responses for each application implemented. The frame types
associated with each of the two applications are identified in Q.921/table 5.
Frame types associated with an application not implemented shall be discarded and no action
shall be taken as a result of that frame.
For purposes of the LAPD procedures in each application, those frame types not identified in
