This parameter indicates the type of test to perform. It
has no effect until frxStartTest is set to start the test.
1=Set up a loopback and run a PN-2047 Bit Error Rate Test.
2=Run a (straightaway) PN-2047 Bit Error Rate Test. This
test assumes a loopback has been manually set up somewhere
downstream or another test set running PN-2047 BERT is
connected downstream.
3=Send corrupted CRC on the DSL. This has no effect on the
frame relay CRC, only the out-of-band DSL CRC (used for
performance monitoring) is corrupted.
4=Set up a loopback at the specified location to loop the
frame relay or PPP data in both directions.
5=Setup a local loopback on all 4 ports. frxTestPort and
frxLoopLoc are ignored for this test.
