conveys a DLSDU from the DLS provider to the DLS user. The DLS provider guarantees to deliver each DLSDU to the local DLS user in the same order as received from the remote DLS user.

The message consists of one or more M_DATA blocks containing at least one byte of data.
The message is valid in state DL_DATAXFER.
The resulting state is unchanged.
