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.
