The function of this terminal is to prevent "0" dialing
and "9" dialing under PABX system long distance
call control. When the first key input after reset is 0
or 9, all key inputs, including the 0 or 9 key, become
invalid and the chip generates no output. The
telephone is reinitialized by a reset.
