| Abstract: | To implement multiple E ls in module without using special chip, and to improve the portability of the design, the scheme of hardware and software of E1 relay unit is introduced, and the design issues of E1 interface, E1 reception and transmission and MCC reception and transmission are analyzed. The key technique is explained in detail. Through an analysis of the result of per- formance test,it can be concluded that the design has the advantages of low cost, low power and independence on special chip. |
