Abstract

PURPOSE:To realize the economical waiting type tandem system, by providing the mutual connection trunk usable commonly from the attendant board, in connecting the relay lines mutually in waiting time system. CONSTITUTION:When the oscillation connecting operation is made by the attendant board operator ATTA to the relay line T1, the one vacant trunk is selected from all the mutual connecting trunks CT located in the main channels NW, the terminal F of the trunk CT and the relay line T1 outgoing trunk OGT1 are connected, the terminal B and the terminal T of the OPTA are connected, and the attendant board ATTA operator and the relay line T1 operator can be communicated. When the operator releases the tandem connection, the terminal B of the mutual connection trunk connected with the operator trunk OPTA before and the outgoing trunk OGT2 for relay line T2 are connected, allowing to make mutual communication between the called parties on the relay lines T1 and T2.
