DDSINV:
This bit is valid in T1 DM format when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
A transition from ‘0’ to ‘1’ on this bit wil invert one 6-bit DDS pattern.
This bit is cleared when the inversion is completed.
CRCINV:
This bit is valid in ESF format when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
A transition from ‘0’ to ‘1’ on this bit will invert one 6-bit CRC pattern.
This bit is cleared when the invertion is completed.
FsINV:
In SF, T1 DM formats, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
A transition from ‘0’ to ‘1’ on this bit will invert one Fs bit (the F-bit in even frame).
In ESF format, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
A transition from ‘0’ to ‘1’ on this bit will invert one Frame Alignment bit.
In SLC-96 format, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
A transition from ‘0’ to ‘1’ on this bit will invert one Synchronization Fs bit.
This bit is cleared when the inversion is completed.
FtINV:
In SF, T1 DM, SLC-96 formats, this bit is valid when the FDIS bit (b0, T1/J1-062H,...) is ‘0’.
A transition from ‘0’ to ‘1’ on this bit will invert one Ft bit (the F-bit in odd frame).
This bit is cleared when the inversion is completed.
