This attribute specifies the types of the test frames to be transmitted
during the ATM connection test. It must contain at least one of the
following:
loading: A set of 'loading frames' is circulated over the link as
rapidly as possible. This frame type should be selected when the
test is intended to verify the operation of the connection under a
specified load. These frames are not checked for bit errors.
verification: A single 'verification frame' is transmitted over the
link; when the frame is returned, its contents are verified and the
next verification frame in the series is transmitted. This frame type
should be selected when the test is intended to verify that frames are
not being corrupted as they pass over the connection.
