ITT Telephone Instrument
Maintenance Manual

Courtesy of Robert A. Friedmar

Much of the information contained in this manual parallels similar equipment information for Western Electric, Stromberg Carlson, etc. since Western Electric licensed much of their technology and product specifications to companies like ITT who provided equipment to the "Independent" telephone companies.  Currently, only chapters 1 and 2 have been scanned and about half of chapter 3.  Chapter 3 consumes one-half of the total pages in this manual and will take some time to scan/crop/clean the images - more time than I have spare time to do right now but hopefully in a few months I will have completed this manual.  All files linked from the Table of Contents below are in PDF format.  If you do not have the Adobe Acrobat Reader for opening and printing this type of file, you can download the latest version from the Internet.
