Excerpt from Index to the Bell Telephone Magazine, 1948, Vol. 27 In compiling traffic data, it is noted that many foreign telephone systems have various categories of calls, such as those with Avis d'appel or Pre avis (messenger calls), lightning calls, urgent calls, and fixed time calls, which are charged for at higher rates and have priority over ordinary messages. In times of peace, all calls in the United States are on a light ning or urgent basis, without priori ties, and are charged for at the nor mal or ordinary rate.
