摘　　要：为简化常用的E1接入SDH系统,提出并验证了一种基于FPGA技术来实现E1业务直接接入SDH体制的设计方法,其核心是利用FPGA实现TUPP、E1映射及复用等功能。由于主要功能都在FPGA内部实现,且模块可重构,因此该设计硬件架构简单、集成度高,只需要少量电路就可以实现不同E1接口数量到SDH的接入。A method to simplify the E1 interface to SDH system using the ordinary way has been given and verified, which is based on FPGA technology. The difference is that this method uses FPGA to implement TUPP, E1 mapper, multiplexer and other functions. Because most functions are implemented inside FPGA, the hardware system is simple and highly integrated. So that just needs few necessary circuits, the method can satisfy different requirements of E1 interface amount because of reusable design conception.
