LRDI

LRDI:

The LRDI bit controls the insertion of line remote defect indication (LRDI).

When LRDI is a logic one, the S/UNI-PLUS inserts line RDI into the transmit

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. The LRDI bit is logically ORed

with the external TLRDI input.

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. The

APS bytes may also be inserted using the TTOHEN and TTOH inputs. Values

inserted using the TTOHEN input take precedence over the source selected

by the APSREG bit.

Reserved:

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