    摘要： A cable connection structure is provided, which has circuit boards of an electronic apparatus connected to each other by a shielded cable for transmission of signals, which is capable of effectively suppressing radiated electromagnetic waves due to resonance from the shielded cable and the circuit boards in an inexpensive and simple manner. At least two connectors are provided on at least two circuit boards, respectively, and a shielded cable connects the circuit boards to each other via the connectors. The shielded cable has a shielding conductor as a covering. The shielding conductor is conductively connected to the metal casing at a position spaced from a position where the shielding conductor and one of the connectors are connected to each other by a distance which is less than a value obtained by multiplying ½ of a wavelength at an upper limit frequency of relevant radiated electromagnetic waves emitted from the shielded cable or ½ of a wavelength at a regulated upper limit frequency of radiated electromagnetic waves by a wavelength reduction ratio at the shielding conductor.

    摘要： A time division exchange provided with a plurality of compression circuits for carrying out signal compression in accordance with a plurality of compression laws and a plurality of expansion circuits for carrying out signal expansion in accordance with a plurality of expansion laws is operated in the following manner. In a case where the exchange is used as an originating exchange, a compression circuit provided in the originating exchange for carrying out signal compression according to a desired compression law is selectively used at each time slot, and information on the desired compression law is sent out from the originating exchange. Further, in a case where the exchange is used as a destination exchange, an expansion law to be used on the receiving side is selected on the basis of the above information, and an expansion circuit provided in the destination exchange for carrying out signal expansion according to the selected expansion law is selectively used at each time slot.
