The United States nation wide emergency communication network (911 system) is going through the biggest technical overhaul in its history, moving from the old analog phone network to Next Generation 911 (NG911), a broadband system built on a dedicated network called the ESInet. That shift is happening alongside rising cyberattacks, a worsening dispatcher shortage, chronic funding gaps, and real disparities in who gets fast, accurate help. Despite how much regulators and vendors write about 911, little academic work treats it as one system worth studying in its own right. This paper reviews the evolution, architecture, and technological transformation of the US 911 ecosystem and the resilience challenges it now faces, and proposes the Emergency Communications Resilience Framework (ECRF), with a maturity model for applying it, as a way to assess resilience across several dimensions at once. The method is a documentary and literature review of 52 sources from 1996 to 2026: peer-reviewed research, FCC and NHTSA records, CISA guidance, NENA and APCO standards, and case law. The main finding is that better technology alone cannot fix 911. Five resilience dimensions, infrastructure, cybersecurity, operations, workforce, and innovation, have to hold up together, and workforce and funding shortfalls are limiting what NG911 can actually deliver. For policymakers, PSAP administrators, and researchers, the ECRF offers a practical way to spot where a jurisdiction is falling short and where investment should go next. It is a conceptual tool, not yet a tested one, built around the US system, so empirical testing and international comparison are natural next steps.
Emergency communication is one of the most important, and least studied, categories of public infrastructure in the country. Every year, the US 911 system handles roughly 240 million calls across 5,748 Public Safety Answering Points (PSAPs), acting as the front door for police, fire, and emergency medical response nationwide (National 911 Program, 2022). The number itself dates to 1968, when AT&T designated 9-1-1 as the national emergency number following a 1967 recommendation from the President’s Commission on Law Enforcement and Administration of Justice (AT&T, 1968; President’s Commission on Law Enforcement and Administration of Justice, 1967). Since then the system has gone through roughly four eras: basic analog 911, Enhanced 911 (E911), wireless E911, and the Next Generation 911 architecture now being built out. Each shift happened because the phones people were actually using had outrun the network built to receive emergency calls from them.
