Best Practice Detail

13-12-3223

Network Operators, Service Providers and Public Safety should implement dedicated and as diverse trunk groups as feasible and commercially reasonable as possible between the Mobile Switching Center (MSC) end office or similar source and the E9-1-1 Selective Router (SR) or Legacy network Gateway (for NG9-1-1), based on the geography served by the default Public Safety Answering Points (PSAPs).

Status: Rollover New

References/Comments: This should be done rather than aggregating traffic from centralized switching architectures serving wide spread geographic areas onto a single trunk group to the E9-1-1 Selective Router. This should be done in conjunction with the local PSAP jurisdictional authorities to ensure that correct choices are made.
