In ST-BUS Mode 1, echo canceller I/O channels are assigned to ST-BUS timeslot 0. Note that the user could configure PORT1 and
PORT2 into different ST-BUS modes.
In ST-BUS Mode 2, echo canceller I/O channels are assigned to ST-BUS timeslot 2. Note that the user could configure PORT1 and
PORT2 into different ST-BUS modes.
