This type of coinbox was introduced in 1958 at the same time as Subscriber Trunk Dialling and tariffs based on timed units/distance. It worked in conjunction with a coin and fee check relay set in the exchange. Money was inserted when the called customer answered the telephone or the credited time ran out.
