The AE-50 phone was often called a coffin or jukebox phone due to its unique shape. Much like "ribbon cable," its signature shape has earned names like "flat cable" and "multi-planar cable." The purpose of this arrangement is to maximize the potential number of wires while minimizing the footprint, which allows for many wires to fit in tight spaces. I currently have a number of examples of these telephones, and as I get the time, I will be posting photos of AE phones in my collection. Hmmmm, it doesn't look like any other phone they might have seen. One notable difference between these and their WE/NE counterparts, is that the switchhooks on AE models were designed in a such a way that it was virtually impossible to hang them up improperly, leaving the phone line open. This is the way I remember the plant in the "Good Olde Days". This plant closed down in 1983 and sold to NovaTel. GTE Automatic Electric/Microtel and Phillips were two of the major employers in Brockville - both major employers until they shut down some 50 years later. Brockville was a telephone town - the home of Phillips Electrical Works, and later the home of GTE Automatic Electric.

While there are plenty of DIY tasks that you can sharpen your handy skills on, home electric repair isn’t one of them. There are two variations of GB/T plugs: one for AC charging and one for DC fast charging. Some charging stations come with cables attached (these are called tethered charging stations) and others require you to bring your own. The unshielded twisted pair (UTP) cable includes two wires that are twisted as one, so this cable is used for the transmission of signal & video applications, telephones, data networks & security cameras. These cables are very popular due to moisture, changes from high tolerance to temperature & other ecological factors for transmission or communication requirements. The cross-section of conductors must be selected according to the expected load, voltage drop, ambient temperature and installation. The most commonly used conductors are copper and aluminum. These cables are available in small size but we can extend by using some adapters based on the requirement. A bit extra will be needed at either end, and it is also worth having a small allowance because twisting the wires together will result in a small reduction on the cable length when compared to the original wire lengths.

Ensure there is sufficient twist in the cable to keep the wires closely twisted together and prevents them from falling apart. The first solution to these problems is to keep cable lengths in buildings short since pick up and transmission are essentially proportional to the length of the cable. When I left home, this collection went by the wayside until years later I got back into collecting phones, first concentrating on Western and Northern Electric phones, then most recently Phillips/Automatic Electric. 22, 1954. The telephone manufacturing operations were then transferred to the new plant from the old Phillips plant. On August 30, 1999, the plant was sold to Sanmina SCI Systems, Inc. which operated it as a circuit board manufacturing plant for two years until it shut its doors finally in November 2002 putting 850 people out of work. Some, such as the AE 40's and 50's were manufactured by both plants, manufacturing operations moving "up the hill" with the opening of the new factory. Some, such as the AE payphone shown below, were manufactured at Automatic Electric facilities in the U.S. The Brockville plant became known as GTE Automatic Electric. Two years later, the new Brockville plant served as the model for the huge plant built in Northlake, Illinois by the parent company.

A third plant was located in Richmond, BC., according to a GTE Automatic Electric booklet commemorating 25 years in Brockville. This was a desk phone manufactured first by Phillips Electrical Works, then after 1954, by the Automatic Electric plant in Brockville. This AE-50 wall phone also was first manufactured by Phillips Electrical Works, then after 1954 by the Automatic Electric plant in Brockville. When Microtel wound up operations, the Brockville plant then was sold on January 24, 1990 to Nortel then becoming known as Brock Telecom. Brock Telecom took over support for the GTD-5 digital switches in Canada. In February, 1979, the British Columbia Telephone Company (BC Tel) announced its plan to purchase AE's holdings, along with GTE Lenkurt Electric (Canada) Ltd. The majority of early Canadian AE's were manufactured in Brockville. Most of the telephones shown on this page are manufactured by the two Brockville factories. Thanks to Terry Biddlecombe, Mike Magnus, Bruce Denny, and Roger Conklin for helping me fill in the changes of ownership and dates thereof in the years following my leaving Brockville. It was manufactured for 4 years from 1934 to 1938. AE 34s had a single hook switch button, mounted halfway between the handset support ears, and only a single cord entry/exit point halfway across the back as compared to the late AE40 which had a button on each ear, and two cord holes, one in each back corner.
