To answer a precedence call:
If your telephone is idle and you receive a call with a precedence level higher than routine, you will hear the MLPP precedence ring. If your telephone has a display, it will indicate the precedence level of the incoming call.
1.When you hear the MLPP precedence ring (short ring, very short pause, short ring, long pause), answer the telephone. As you talk, the display indicates the precedence level of the call as well as the duration of the call.
2.When you have finished the call, hang up.
To respond to preemption:
zIf you are engaged in a call and hear a continuous preemption warning tone, a call of higher precedence is attempting preemption. Hang up immediately, wait for an MLPP ring, and then answer the telephone. As you talk, the display indicates the priority of the call as well as the duration of the call.
zIf you are engaged in a call and hear three seconds of preemption tone, it means that the person you were talking to has been preempted. You should hang up. You may place another call if required.
