摘　　要：提出了可交换数字电路倍增的概念,并提出了在电路交换网上实现可交换数字电路倍增(ED CM)的技术。克服了传统数字电路倍增设备只能点对(多)点传输的局限,可方便的组成EDCM网。The concept of exchangeable digital circuit multiplication (EDCM) is proposed.The implementation technique of EDCM is put forward. The limitation of traditional DCME (only point to (multi-)point transmission) is overcome by the new one. EDCM network can be easily formed.
