The SPECTRA-155 Auto Trace Message Mode 1/2 Control register along with
individual alarm enable registers listed in the bit descriptions allow auto assertion
of consequential actions based on mode 1 and mode 2 section trace message
(J0 byte) and path trace message (J1 byte) unstable states.
AUTOSTIU2:
The auto section trace identifier unstable mode 2 bit controls auto assertion
of a consequential action (receive Path AIS and/or Line RDI) due to the
detection of a section mode 2 trace identifier unstable (TIU) state. When
AUTOSTIU2 is set high, mode 2 TIU can automatically assert receive Line
AIS as controlled by the RTIUINS bit in the SPECTRA-155 Receive Line AIS
Control register or Line RDI as controlled using the RTIUINS bit in the
SPECTRA-155 Receive Line RDI Control register. When AUTOSTIU2 is set
low, mode 2 TIU does not affect consequential actions.
AUTOPTIU2#1, AUTOPTIU2#2, AUTOPTIU2#3:
The auto path trace identifier unstable mode 2 bit controls auto assertion of a
consequential action (receive Path AIS, Path RDI, Enhanced Path RDI,
and/or DS3 AIS) due to the detection of a path mode 2 trace identifier
unstable (TIU) state.
When AUTOPTIU2 is set high, mode 2 TIU can automatically assert receive
Path AIS as controlled by the corresponding TIUPAIS bit in the
SPECTRA-155 Receive Path AIS Control (#1, #2, #3) registers or Path RDI
as controlled using the corresponding TIUPRDI bit in the SPECTRA-155 Path
REI/RDI Control (#1, #2, #3) registers or Enhanced Path RDI as controlled
using the corresponding TIUEPRDI bit in the SPECTRA-155 Enhanced Path
RDI Control (#1, #2, #3) registers or DS3 AIS as controlled using the
