                response to a requested loopback state that the
                interface does not support.  The values mean:

                sonetNoLoop
                     Not in the loopback state.  A device  that
                     is not capable of performing a loopback on
                     the interface shall always return this  as
                     it's value.

                sonetPayloadLoop
                     The received signal at this  interface  is
                     looped  through  the device. Typically the
                     received signal is  looped  back  for  re-
                     transmission  after  it has passed through
                     the device's framing function.

                sonetLineLoop
                     The received signal at this interface does
                     not  go  through the device (minimum pene-
                     tration) but is looped back out.
