NAME AND DESCRIPTION
Transmit Japanese CRC6 Enable.
0 = use ANSI/AT&T/ITU CRC6 calculation (normal operation)
1 = use Japanese standard JT–G704 CRC6 calculation
Local Loopback.
0 = loopback disabled
1 = loopback enabled
Line Interface AIS Generation Enable.
0 = allow normal data from TPOSI/TNEGI to be transmitted at TTIP and TRING
1 = force unframed all ones to be transmitted at TTIP and TRING
