摘要
无线线路由话音通信在应急通信中广泛应用,但是,由于无线通信频段各异、体制差异大,普遍存在无线通信系统之间通联问题。采用语音卡板件,基于状态迁移编程实现的自动电话转接装置,提供各无线通信系统话音层次的自动转接途径,实现应急条件下系统间通信功能,可以显著提高应急条件下的无线通信系统整体通信能力。实际使用表明,该装置具备自动、手动转接功能,可以实现内线之间、外线之间、内外线之间的相互转接,满足设计要求。
Wireless few routes voice communication systems are used in urgent communication area widely. But there are many problems of communication because of the different frequency and system. The telephone auto switch device programmed on status shift with sound card can offer the route for voice communication inter-system. It can increase the integrated wireless communication capability on the urgent communication condition. Actual use show that the device has automatic, manual switching function, it can switch the telephone between the inner, between the outside, between inside and outside. It meets the design requirements.
