Abstract
A 911 emergency response system that includes a location identification module, preferably in solid state circuit form, associated with each residence or each extension of a PBX is disclosed. Preferably, the location identification modules are powered by telephone line voltage. A location identification module is enabled when its associated telephone goes off-hook and an emergency code, e.g., 911 is dialed. Thereafter, in response to an inquiry from the emergency response center that receives the emergency call, the location identification module sends the location of the associated telephone to the emergency response center operator where the location is displayed on a dispatcher'"'"'s console.
