								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
