This is an Expanded test mask of the prtGenTestMask object.
The prtGenTestMask object reached its maximum, being an Integer with 31 bits.
This object indicates which tests from the  'prtGenTestCmdXP' list are 
allowed for the selected port.
If a specific test is allowed, its respective bit will be SET 
in the mask :

 e.g : If the return value is  00000003 hex  ->
       Bits 1 & 2 are set -> the allowed tests are :
                                    local-loop
                                    remote-loop
