Upon receipt of a BIST Message, with a BIST Carrier Mode BIST Data Object,
the UUT Shall send out a continuous string of BMC encoded alternating "1"s
and “0”s. The UUT Shall exit the Continuous BIST Mode within
tBISTContMode of this Continuous BIST Mode being enabled(see
Section 6.6.7.2).

6.4.3.2 BIST Test Data
Upon receipt of a BIST Message, with a BIST Test Data BIST Data Object,
the UUT Shall return a GoodCRC Message and Shall enter a test mode in which
it sends no further Messages except for GoodCRC Messages in response to
received Messages. See Section 5.9.2 for the definition of the Test Data
