In most applications of synchronous data trans- type of information. Two examples of this type of missions, the user is not given the status of signaling decode are as follows: when termination of decoding is requested. Most devices have a simple on/off switch and the user The receiver can simply give information to the simply interrupts the power to the receiver. In some display to tell the user the receiver's status and if the applications it is useful to know the status of the user wishes to continue with the shutdown procedure. decoding receiver before the decision is made to Examples of typical messages are given in Figure 1. remove power. There can be various versions of this Simple Status Update Before Acting UNlTM3TSYNCHFiONOUS RECEIVER OFF Status Acknowledged FIGURE 1 0 MotOlOla. 1°C. 1991 143 0 M MOTOROLA INC. Technical Developments Volume 12 April 1991 The second example is a bit more sophisticated than the first. This method relies on the receiver to send information to some back end process which will selectively shut down the receiver when it is no longer receiving data and is not synchronous. Examples of this can be seen in Figure 2.
