Duplicate optical fibers connect between a base station controller and a radio base station for each route. The duplicate optical fiber is connected to each of the radio base stations for each route through a star coupler. The radio base stations are arranged in each of areas so that the radio base stations for different routes are arranged adjacent to each other.

Portable telephone system

A facsimile system with the body thereof usable as a subunit of a cordless telephone is disclosed. A parent unit is connected to the telephone line. A facsimile subunit is connected by radio to the parent unit. A telephone subunit is also connected by radio to the parent unit. A circuit included in the parent unit detects a signal indicating that the other party is in facsimile transmission mode. When a call signal is detected from the telephone line, the parent unit connects the line. When a CNG signal is detected, on the other hand, the parent unit connects the facsimile subunit by radio. In the case where a CNG signal is not detected, the parent unit starts the ring-up tone on the telephone subunit. An AGC circuit and a voice mute circuit are included in the parent unit.

Cordless subunit facsimile system

A facsimile apparatus which utilizes a dialing signal of a tone signal and can be used as a called-side communication apparatus to print desired character string information through a simple operation of a calling-side telephone set, and also a facsimile communication method in the facsimile apparatus. In the called-side facsimile apparatus, a character string information memory stores therein a plurality of character string information and unique numbers associated therewith; whereas a character information memory stores therein image information corresponding to the respective character string information. When a user of the calling-side communication apparatus enters a number corresponding to desired character string information, this causes a dialing signal indicative of the number to be transmitted to the facsimile apparatus. In the facsimile apparatus, a control unit converts to image information the character string information corresponding to the number indicated by the dialing signal detected by a dialing signal detector, and the converted image information is printed by a printer.
