  1. The whole calling process of the system is just like that the calling party calls the called one through dialing, and then the called party picks up the telephone after hearing the ring

    該系統的呼叫過程是主叫用戶通過撥號呼叫被叫用戶，被叫用戶聽到振鈴聲後接聽電話。
  2. The dialing is slow and the system ca n ' t ensure the calling party fast and accurately put through the called one who is asked for receiving. 5. the bell ring is so low that the workers ca n ' t hear in the large - scaled working space with strong noise

    它存在的缺點有：工程布線麻煩、費用高；電話線路成本高且利用率低；系統可靠性差；呼叫速度慢，並且不能保證主叫用戶快速、準確地找到需要接聽的被叫用戶；振鈴聲難以保證在大范圍、強噪聲的生產場所下的工作人員接聽到。
