Regulations of Connecticut State Agencies
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 receive a busy signal during the average busiest hour. The service population and the call volumes experienced by the public or private safety answering point shall determine actual trunking levels.
