This paper addresses the Alliance for Telecommunications Industry Solutions’ (ATIS) Network Reliability Steering Committee’s (NRSC’s) review of Centralized Automatic Message Accounting (CAMA) trunks used in some 9-1-1 configurations. As part of this review, incidents of high call volume and the current 9-1-1 architecture were reviewed. This report provides the industry with recommendations to assist in mitigating these types of incidents in the future; as well as, to maximize 9-1-1 call throughput to PSAPs during high call volume conditions.
