MTRK:
The MTRK bit forces trunk conditioning (i.e., idle code substitution and
signaling substitution) when MTRK is a logic 1. This has the same effect as
setting data substitution to IDLE code on time slots 1-15 and 17-31 (setting
bits SUBS and DS[0] to binary 10 in time slots 1-15 and 17-31) and sourcing
the signaling data from the TPCSC stream, if SIGEN is logic 1. When SIGEN
is logic 0, TS16 will be treated the same as time slots 1-15 and 17-31 and will
contain data sourced from TIDL. TS0 data is determined by the control bits
associated with it and is independent of the value of MTRK.
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.
SPATINV:
The SPATINV bit is a diagnostic control bit. When set to logic 1, SPATINV
forces the signaling multiframe alignment signal written into bits 1-4 of TS16
