LRDI:
The LRDI bit controls the insertion of line remote defect indication (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
STS-3c stream.
APSREG:
The APSREG bit selects the source for the transmit APS channel K1/K2 bytes. When
APSREG is a logic zero, 0x0000 is inserted in the transmit APS K1 and K2 bytes. 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.
