Remreed Switching Networks for No. 1 and No. 1A ESS: Physical Design of Remreed Switching Networks

Abstract

Five new switching frames have been designed for use in No. 1 and No. 1A ess central offices. These new frames utilize the recently developed remreed sealed contact and are equipped with electronic network controllers. The new remreed switching frames occupy approximately one‐quarter the floor space required for the ferreed switching frames that they replace. Other design features include improved maintainability, reduced installation interval, and reduced cost. This paper describes some of the more significant physical design features incorporated in these five new frame designs.

“…The system message nomenclature is in this sense not compatible with the remreed physical design. 6 The office craftsperson needs to make a mental translation of frame into circuits and bay into mounting plate.…”
