Abstract

A subscriber receives substantially uninterrupted telecommunications service at a station set (12) by virtue of a connection between the set and a telephone facility (20) via a preferred communications channel (14) and an alternate communications channel (16). First and second intelligent switching means (44, 46) are associated with the subscriber station set and with the telecommunications facility (20), respectively. The first and second intelligent switching means route calls from the station set and the telephone facility to the telephone facility and station set, respectively, based on the availability of the first and second communications channels and on the characteristics of the call.
