The GX6188 has an eight-signal global bus that can be used to interconnect multiple cards which adds more switching points and/or resources for a test system. 5 shows a switching system with N GX6188s, which yields N times 104 by eight by N times 8 switching configuration. For example, connecting three GX6188 boards will create a switching system with a 312x8x24 configuration.
