Abstract
An arrangement for enhancing the capabilities of emergency service provisions for telephone stations served by a cable system. In accordance with the prior art, telephone stations served by cable systems are frequently provided with access to an emergency telephone line for making emergency calls when the cable system lacks power, or is otherwise inoperative. In accordance with this invention, the emergency service line is used for making incoming calls directed to all telephones connected to the emergency line, using a different telephone number for the emergency call. Outgoing service is also provided to the telephones connected to the emergency line. Advantageously, the value of the emergency line service is substantially enhanced.
