Reserved:
The reserved bit must be programmed to logic 0 for correct operation.
FPATINV:
The FPATINV bit is a diagnostic control bit. When set to logic 1, FPATINV
forces the frame alignment signal (FAS) written into TS0 to be inverted (i.e.,
the correct FAS, 0011011, is substituted with 1100100). When set to logic 0,
the FAS is unchanged.
SPLRINV:
The SPLRINV bit is a diagnostic control bit. When set to logic 1, SPLRINV
forces the "spoiler bit" written into bit 2 of TS0 of NFAS frames to be inverted
(i.e., the spoiler bit is forced to 0); when set to logic 0, the spoiler bit is
unchanged.
REMAIS:
The REMAIS bit controls the transmission of the remote alarm indication
signal. A logic 1 in the REMAIS bit position causes bit 3 of NFAS frames to
be forced to logic 1; otherwise, bit 3 of NFAS frames is determined by the
settings in the Transmit Configuration Register.
AIS:
The AIS bit enables the TRAN to generate an unframed all-ones AIS alarm.
When AIS is set to logic 1, the TDP/TDN[x] outputs are forced to pulse
