Abstract

PURPOSE:To enable the charging of a two-party-line call, by making a reverting call trunk detect the answer of a called party line in distinction from the abandonment of a calling party line. CONSTITUTION:When reverting call trunk RVT is actuated, a call signal is transmitted to calling subscriber A and called subscriber B. Relay A operates again as the result of the answer of either subscriber A or B, and for the purpose of the discrimination between the answer of the called subscriber and the abandonment of the calling subscriber, tone receiver TONEREC is grounded to operate answering relay E when the sound frequency during a lead-in call arrives at TONEREC for a certain time by the make contact of relay A and the break contact of relay RT via the call line of RVT. Then, the charging of the calling subscriber is done through the operation of relay E.
