1997年6月上旬，响水县供电局机关的外线电话全部换成内部磁卡电话。拨打电话需使用随机配发的内部磁卡。这是该局增收节支的又一举措。该局继对所辖八座变电站的外线电话实行费用包干使用后，发现局机关的外线电话费用仍不易控制，于是便推出外线电话磁卡化，按工作需要配发磁 In early June 1997, the external telephones of the Xiangshui County Power Supply Bureau were all replaced by internal magnetic card telephones. Dialing a phone requires the use of a randomly distributed internal magnetic card. This is another measure for the increase in revenue and savings of the Bureau. After the bureau’s subsidy of the external calls of the eight substations under its jurisdiction, it was found that the external telephone charges of the bureau were still difficult to control, so the external telephone was carded and the magnetic was allocated according to the needs of the work.
