 								2. Open and close a bulk pipe on default setting 0

 								3. Select alternate interface setting 1 and establish a pipe then close it

 								4. If alternate interface selection fails, establish that the pipe previously 

 								   opened in step 2 can be opened again.

 	@SYMTestExpectedResults 	Pipes can be established in either interface setting
