The first part of this paper reviewed the first one-third of the report including the Title of the Paper, the Background to its development, the Members of the Subcommittee that developed the report, Definitions, Table of Contents, Scope and Section 4. This second part of the paper will look at Section 5 (Susceptibility of Communications Receivers to Commercial EDP/OE Emanations) of the Report.

GR-1089-CORE has always required the Cross Voltage Test in its Section 4. This test simulates communication wires contacting power wires. Previously, the Cross Voltage Test has been conducted at 600V, but the new Issue 6 has decreased this voltage to 425V. The 425V test uses the same current levels as were required for the 600V test, so this is a decrease in the amount of power that is required to be produced by testers designed to perform the Issue 6 Cross Voltage Test. In this article, we will address the two new tables describing the tests, discuss changes and note the tests that have not changed, and offer some general guidelines for parties who would like to modify existing Cross Voltage Testers to perform the Issue 6 Test Suite at 425V.
