《电子技术》从本期起开辟了“1240技术”专栏,这既是对上海贝尔的大力支持,也是为我国程控电话通信事业发展作出新贡献。对此表示衷心感谢和祝贺。希望这个专栏成为广大用户和工技人员交流经验、切磋技术、提高维护管理水平的一个重要园地,预祝这块新生园地不久将开出灿烂之花。上海贝尔电话设备制造公司生产的1240(也称S12)程控电话交换系统是国际电话电报公司(ITT)于80年代初开发的,其成果由阿尔卡特集团(ALCATEL N.V.)继续开发、发展并完善,成为国际上最新一代的大容量全数字程控电话交换系统,适
“Electronic Technology” has opened the “1240 Technology” column from this issue. This not only gives strong support to Shanghai Bell, but also makes new contributions to the development of China’s programmed telephone communications. My heartfelt thanks and congratulation! We hope this column will become an important field for the exchange of experience among the users and engineers and technicians and for the improvement of the management level. I wish this new campus will soon open a splendid flower. The 1240 (also known as S12) program-controlled telephone switching system, produced by Shanghai Bell Telephone Equipment Manufacturing Co., was developed by ITT in the early 1980s and its work continued to be developed, developed and refined by ALCATEL NV, Become the latest generation of high capacity all-digital program-controlled telephone exchange system, suitable
