The switch to a unit call system is the subject of much public discussion, and becomes the main news item on the day the change is made. The switch is prompted by the need to eliminate inequities in the flat fee subscription system, and to obtain financing for extension of lines. Another consideration is reducing busy signals due to unnecessary calling, in some cases involving complaints about phones that remain connected all day. In addition to a basic fee of 40 yen, a standard charge of 2 sen per call is adopted.
