PURPOSE:To secure extremely easy performance for the wiring design, the continous line design plus manufacture and inspection, by distributing the magnetic holding type relays and the call monitoring relays in vertical division and with every trunk circuit. CONSTITUTION:Magnetic holding type relay S and T plus call monitoring relay A, E and L are packed in vertical division to the trunk package for each trunk circuit. As a result, the package is possible with every circuit, and the performance can be facilitated greatly for the wiring design, the continuous line design plus the manufacture and inspection since both the wiring form and the continuous line state feature an identical repetition. |
