Interface modules (line cards) Huawei depending on the type and functions are divided into the following types: Main Processing Unit (MPU) - Main Processor, Switch Fabric Unit (SFU) - Switching block, Centralized Monitoring Unit (CMU) - Centralized monitoring unit, Line Processing Unit (LPU, also called interface card or line card) - Linear Processor (LPU, also called interface card or line card, and others.
These modules add functionality to existing modular routers or switches. Each Huawei series or sub-series has its own interface modules, line cards, processor and network devices.
These modules can expand the functionality at high speeds, such as 100GE, or increase the performance of a router or switch. Huawei.
