DSP Processing Modules for S1/X2 Interface
Besides the AZP-500/1400 platform, ANPro-800 is another powerful Compact-PCI based proprietary platform (Figure 1) prepared for XD and HD systems. It enables C-plane and U-plane traffic generation for the S1/X2 interface. These DSP processing modules are also the Artiza’s original state-of-the-art traffic engine (Figure 2), which can simulate comprehensive EPCs as S1 interface and eNBs located beside as X2 interface. One interface module with four GbE SFP ports can be coupled to multiple DSP modules through a cascaded backplane depending on different user requirements for the traffic level. This powerful architecture can simulate 8 nodes in LTE core network simultaneously with various protocols and tremendously high capacity of up to 840 UEs x 6 sectors per chassis, when used with the XD and HD models.
