BRITISH ERICSSON (ETELCO)
PRODUCT NUMBERING
 


All British Ericsson products had a product code number and this is generally found on the bottom or rear of the item. 

The wiring diagram found inside all Ericsson products has a number, which may start with an N - this is the diagram number and NOT the product code.  Use the Ericsson telephone spreadsheet to cross reference the product code to the diagram number.

The early product codes were just numbers only. i.e. 340
The early 20th Century models had a letter or letters prefixing a number. i.e. CD2000
The N series products were introduced around the 1920's and this lasted until the 1970's.  i.e. N1003.

The N series normally had a suffix made up of letters and numbers.  i.e. N1440E1.
N1440 is the code/model number, E is the variation and 1 is a revision.
In this case the model N1440E1 is a N1440 telephone, variation E, in black, with a regulator, made for Lever Bros.

To find out specific variations, one has to refer to the Ericsson factory documentation.  Some models had around 100 variations - too many to list here.

Tropical versions of any N series model have a T at the end of the code number.

During the late 1970's the code numbers changed to all number codes separated by slashes. i.e. 617/1/02188.  This series was used by Plessey and GPT telephone systems as well.
