APS Software Overwrite Value.
This nibble is pro-
grammed to utilize APS bits in the Z7/K4 byte. This nibble
will be transmitted in bits 1:4 of the Z7/K4 byte.

Enhanced RDI-V Software Overwrite Values.
If
VT_ERDI_EN[1

28] (
Table 198
) is a logic one, these bits
are written into the ERDI-V locations of the Z7 byte.
RDI-V Software Overwrite Values.
If VT_RDI_EN[1

28]
(
Table 198
) is a logic one, this value will be written into the
RDI-V location of the V5 byte.
RFI-V Software Overwrite Values.
If VT_RFI_EN[1
—
28]
(
Table 198
) is a logic one, this value will be written into the
RFI-V location of the V5 byte.

This byte is programmed to utilize
the overhead bits in asynchronous VT/TU mappings.
VT_OBIT_INS[7:4] will be transmitted in the byte follow-
ing J2 and VT_OBIT_INS[3:0] will be transmitted in the
byte following Z6/N2.
Z6 Software Overwrite Values.
This byte is pro-
grammed into the outgoing Z6/N2 location when
