Abstract

See full text

An off-site remote telephone service system is connected in series with subscribers to the system and the associated central telephone office for providing to each of the subscribers additional telephone services. The telephone service system is connected in series between the subscribers and the main frame distribution mechanism of the central telephone office. In addition to the wires connecting the telephone service system in the series connection, the system also has at least one independent telephone line for placement of calls, which telephone line extends to the central office. All of these telephone lines are connected to a control switching mechanism of the telephone service system. The control switching mechanism includes a bridging mechanism for coupling a subscriber telephone line either to a continuation of the subscriber telephone line or to one of the independent telephone lines of the system for placement and receipt of calls for enabling normal service by the subscriber. The telephone service system further includes a special service mechanism acting as an intercept between the subscriber telephone and the central office for providing special services to the subscriber. Exemplary of such special services are access to special long distance telephone lines, telephone answering services, electronic mail services, word processing services, computer services and conference call services along with many other advanced services currently available.
