The invention relates to automatic switching and can be used to build nodes for automatic switching of quasi-electronic automatic telephone exchanges of small and medium capacity. The effect is to reduce the number of locks for regular subscribers and provide low-blocking communication with additional services for privileged subscribers. The effect is achieved by introducing additional switching units and information storage and output units and connecting them to the switching units of the first link 1 ₁ - 1 _n and the second link 2 ₁ - 2 to the nodes of the incoming communication S ₁ - S _m and the nodes of the outgoing communication 6 ₁ - 6 _{m n}
