Abstract

PURPOSE:To automatically replace junctors and reduce the amount of work required for additionally installing network. CONSTITUTION:With TT type network containing a junctor switch, the number of junctor highways from one T switch can be reduced to a minimum number of one by time sharing the connection between junctor highway JHWa and JHWb by the junctor switch JSW, thus enabling to reduce the number of cable and facilitate work for additional installation. In case where M is 4, a perfect link system can be made by always arranging the connection fron junctor switch JSW1 to JSW4 as shown by the solid line, that is, for JSW1, slip is O between the in-terminal and out- terminal, for JSW2, slip is 1, for JSW3, slip is 2 and for JSW4, slip is 3 so that the junctor from one primary T switch to one secondary T switch can be uniformly installed as much as the thickness of one JHWa or JHWb.
