when test is stopped by this NMS station, agent sets atmfM4TestResult agent also sets atmfM4TestStatus = ’notInUse’

retrieve any additional test results, and atmfM4TestId if (atmfM4TestId == lock_value+1) results are valid

Once ownership is obtained, an NMS could initiate a test by setting atmfM4VcTestType to pdnATMfM4VcTestOAMLoopbackSegMultiCell to which a loopback location code that uniquely identifies an intermediate point responsible for looping back the cell is appended for ATM OAM F5 Segment loopback test, or pdnATMfM4VcTestOAMLoopbackE2EMultiCell for ATM OAM F5 End to End loopback test. If the loopback location code is absent from the pdnATMfM4VcTestOAMLoopbackSegMultiCell, the loopback is performed at the end of the segment or connection. The Ubiquity ATM unit supports next-hop segment ATM loopback, which means that the Ubiquity ATM unit ignores the loopback location code if the NMS application provides one.

Once a test is started, the SNMP agent will set the value of atmfM4VcTestCode to 1.3.6.1.4.1.1795.2.24.2.6.11.6.1.4 (pdnATMfM4VcLoopbackTestTable) indicating the test statistics are in pdnATMfM4VcLoopbackTestTable. The NMS can retrieve the test results by querying the objects in this table.

The NMS station, the owner of the ongoing OAM F5 loopback test, must explicitly stop this loopback test by setting atmfM4VcTestType to NoTest (0.0) when the NMS no longer needs this test The test result might be available depending upon whether there is enough room in the system.

At any time, an NMS station can set atmfM4VcTestType to “0.0” to abort the ongoing test owned by this NMS.
