Stopping an SSCP-LU Session and an SSCP-PU Session
The SSCP-LU session ends when the host sends the Deactivate Logical Unit (DACTLU) command to the SLU. When the last SSCP-LU session for Personal Communications ends, the SSCP can end the SSCP-PU session by sending a Deactivate Physical Unit (DACTPU) command.
