LRDI:

The LRDI bit controls the insertion of line far end receive failure (LRDI). When LRDI is set to logic one, the TLOP inserts line RDI into the transmit SONET/SDH stream. Line RDI is inserted by transmitting the code 110 in bit positions 6, 7 and 8 of the K2 byte of the transmit stream.

APSREG:

The APSREG bit selects the source for the transmit APS channel. When APSREG is a logic zero, 0x0000 hexadecimal is inserted in the transmit APS channel. When APSREG is a logic one, the transmit APS channel is inserted from the TLOP Transmit K1 Register and the TLOP Transmit K2 Register.

Reserved:

The reserved bits must be programmed to logic zero for proper operation.
