Resilience
A plain old telephone service has high reliability and is unlikely to be affected by local power outages. More modern systems require battery back-up to guard against local power outages. The United Kingdom telephone regulator, Ofcom, has published a guidance note for telephone service providers: "Protecting access to emergency organisations when there is a power cut at the customer’s premises".[2]
