NOTES: If you try to make a higher priority call than is assigned to you, the switching
facility will automatically reduce the priority to your assigned level.
Use of priority calling can break in on a conversation already in progress. If a priority
call is placed to a person making a ROUTINE or lower level priority call, the person
called will first hear a two-second, low pitched, dual tone. The other person will hear a
single, high-pitched tone. The old connection will be broken and the priority caller will
be connected to the desired person.
If a priority call is placed when all available trunk lines are busy, a lower priority trunk
line will be freed for the priority call. Both callers on that trunk line will hear a high
pitched tone before being disconnected.
