He Yun, Zhang Zhizhong, Wang Yongfu, et al. Design and implementation of STM-1 IMA date acquisition card for 3G network testers[J]. 2011,(4):62-65. DOI: 10.13756/j.gtxyj.2011.04.018.
Iub interface is one of the most important network interfaces in 3G radio access networks.In view of the transmission of the Iub interface and the insufficiency of the existing Iub interface data acquisition card
this paper designs a modular channelized data acquisition card
and presents a multiplexin/demultiplexing method for STM-1/E1’ on the basis of space/time division switching and a scanning unit/index-based automatic IMA-acquisition group binding algorithm.Tests and application results show that this card has higher flexibility and compatibility.
