摘　　要：语音压缩技术的进展减少了话音传输需要的带宽,使用传统的64k通道实现传输与交换需要进行码速率的转换。文章提出了一种能够实现子通道交换的数字交换矩阵,配合子通道的传输与交换。文中给出了总体设计方案和关键设计技术,并使用VHDL语言编程实现,利用大规模可编程集成电路芯片FPGA进行了验证。The progress of voice data compress technology reduces the need of transmission bandwidth, so the traditional 64k channel was used to transmit and switch voice data, which needs the code rate conversion. A sub-channel digital switch was put forward, which can realize the sub-channel transmission and switching. The overall design scheme and the key design technology were introduced, and realized by using the VHDL language programming. The large-scale programmable integrated circuit chip FPGA was used to verify it.
