Figure 1: Simplified Un-Shielded Circuit
If the shield is passed through from one cable to another between ABMA3-1 terminations and is not
terminated at the R-Line then this is electrically noisier than having no shield at all. The coupling between
shield and the V and S cores has the effect of giving alternative PSA signal paths that can cause the PSA
Controller and ABMA3s to receive false confirmations on tail end units.
