Abstract

A system for regional and local supervision and monitoring of elevator equipment, that includes a modular system containing a service center set of equipment and an on-site set of equipment connected to at least one building. Communication between these sets of equipment is implemented using a remote communication link. A connection from an elevator car to a service center and from a service center to an elevator car is provided through the on-site equipment. A connection between an elevator car and a preselected service point can be established by the on-site equipment.
