Watchdog Timer
WT = 1 enables the watchdog timer (page 39).
WT= 0 disables the watchdog timer.
B1-channel processing
B1 = 1 enables the microprocessor to access B1-channel data
between IOM-2 and the U-interface.
B1 = 0 disables the function described above.
B2-channel processing
B2 = 1 enables the microprocessor to access B2-channel data
between IOM-2 and the U-interface.
B2 = 0 disables the function described above.
D-channel processing
D = 1 enables the microprocessor to access D-channel data
between IOM-2 and U-interface.
D = 0 disables the function described above.
C/I-channel processing
CI = 1 enables the microprocessor to access C/I-commands and
indications between IOM-2 and U-interface.
CI = 0 disables the function described above.
Monitor-channel processing
MON = 1 enables the microprocessor to access Monitor-channel
messages at IOM-2 and at the U-interface.
MON = 0 disables the function described above.
