TMR扩展接口是一种基于锁步配置的TMR架构的容错设计。图1以简化的方式显示了TMR Expander的基本结构接口。

该模块有三个主要的故障遏制区域(FCR A, B和C)。每个主要的FCR包含扩展总线和模块间总线(IMB)的接口，IMB是到扩展总线的主/备用接口其他TMR扩展器接口在机箱、控制逻辑、通信收发器和电源供应。

TMR extension interface is a fault-tolerant design of TMR architecture based on lock-step configuration. Figure 1 shows the basic structural interface of the TMR Expander in a simplified manner.

The module has three main fault containment areas (FCR A, B and C). Each major FCR contains an expansion bus and Intermodule bus (IMB) interface, the IMB is the primary/standby interface to the expansion bus and other TMR expander interfaces in the chassis, control logic, communication transceiver and power supply.
