ABSTRACT:
Call coverage problems are solved in a telephone communication system by arranging the system on a station orientation basis so that any call directed to a station on any line appearance at that station will be covered by a single button on any one of a number of other coverage station sets. Any other station may also have its calls directed to that same coverage station set and, if desired, to the same call coverage button on the covering set. By separating ringing signals and flashing signals and by handling each on a station basis, it is possible to allow both ringing and visual signals of the call if covered by one station, whereas if call coverage is handled by another station it can be arranged so that only visual signals will be provided.
