Abstract: A key telephone system with a re-dialing feature has a memory with two memory areas. One of the two memory areas is provided for an outside-line call, and the other is provided for an internal-line call to a particular extension. Each memory area memorizes a dialed number therein and replaces a number of the last intended call, previously present in the memory area, with the most recently dialed number. A re-dialing push-button automatically retrieves the number of a last intended outside-line call, memorized in the outside-line memory area, when actuated following a selection of an outside-line call, or the number of a last intended inside-line call to a particular extension, memorized in the extension memory area, when actuated following a selection of an internal-line call to a particular extension.

Abstract: Metal pipes containing optical fibers are connected to each other directly or indirectly by use of a sleeve. In case of using the sleeve, the sleeve is connected at one end to one of the metal pipes, after the optical fibers are connected. Then, the sleeve is elongated by a predetermined length, so that the sleeve is connected at the other end to the other metal pipe. Consequently, no tensile stress resides in the connected optical fibers in the connected structure. When the metal pipes are connected directly to each other, one or both of the metal pipes are elongated, after the optical fibers are connected. Then, the metal pipes are connected by use of the elongated portions. Consequently, the same result is obtained as using the sleeve.
