The number of incoming enhanced 9-1-1 trunk lines to each public safety answering
point and private safety answering point shall be based upon a grade of service of
P.O1. A P.O1 grade of service means that not more than one 9-1-1 call in 100 will

the call volumes experienced by the public or private safety answering point shall
determine actual trunking levels.
