It has to be reminded, that document page 5 (not equal to the PDF numbering) is missing for technical reason; as the XEROX electrostatic HT did fail at a critical moment. This is often being caused by poor maintenance.

Resume of Results

A number of practices are followed in the design, installation and maintenance of German communication cable plant which are different from American general practice. .....



Since the end of the European War a larger number of German cable routes have been discovered that was not shown on the internationally published list (Berne Lists) prior to the War.    The sheath milage at least 100 to 125 percent greater than had been published. While placed and maintained by the Reichspost, the cables were very likely used mostly for circuits provided to the Wehrmacht was stated by Reichhspost peolple. The cables are underground as are also the majority of new repeater stations and many of the large terminal offices at large cities

It is of course important in considering German cable systems and other communication systems to have in mind that great many things which were done were not dictated by service or economy considerations but by military and critical material situations as well as the exploiting of communications for propaganda.


Since the transformation ......


Spiral-four construction seems to have increased in usage since about 1935 .....

Styroflex Spiral-Four:    ... MEK 8 (AEG, AOB) carrierequipment was usually employed as it permits pairing the terminal equipment in such a manner that 6 to 60 kHz band can be transmitted on a pair in the other cable ...
