Best Practice Detail

13-12-3224

Network Operators, Service Providers and Public Safety should use dedicated and diverse Signaling System 7 (SS7) or Multi-Frequency (MF) controlled trunk groups as feasible and commercially reasonable as possible for the normal routing of 9-1-1 calls from originating switching entities to 9-1-1 Selective Routers (SRs) or Legacy network Gateway (for NG9-1-1) rather than using shared Public Switched Telephone Network (PSTN) trunk arrangements and where appropriate and necessary supported by service level agreements. Network Operators, Service Providers, and NG9-1-1 PSAPs should use dedicated, geo-diverse and redundant IP connection points when feasible & commercially available.
