This revision is intended to support every reasonable effort by current ECC Managers to proactively manage public and responder expectations at the local level; support a positive working relationship with the wireless service providers founded on a fundamental understanding of the operational parameters of all wireless E9-1-1 service; along with influencing public policy, including regulatory and legislative action. The ECC Manager should also define, develop, and promulgate performance focused ECC training, maintain active quality assurance efforts, and understand the relationship between these actions and field responder efficiency and safety.
