Ericsson Dialog

Made in Sweden by L. M. Ericsson (no connection with British Ericsson at this time), the desk and wall version of this phone had only a vague resemblance to the GPO Telephone No. 706 (UK).  In Britain it was used with a number of PAX systems installed by Centrum Communications (owned by Swedish Ericsson).  Examples have been seen with letters as well as numbers around the dial; these were made for use in North America.

Colours:
Pale grey is the most commonly seen colour, with a rather strident crimson anodised aluminium dial centre.

Users: 
PAX systems, in particular on crossbar PAXs installed in UK branches of Boots The Chemist.

The Ericsson Dialog is a Swedish telephone model released 1964. Millions of the model were sold and it retained its place in homes well into the 1990s.

In the early 1960's Ericsson hired the Swedish architecture and design company Ahlgren, Olsson & Silow (AOS) to develop Dialog, a new standard telephone that was to apply high end technology and reach international markets. Dialog attained great popularity and maintained its place within homes into the 1990s. This design classic has become an object of desire amongst collectors and telephone enthusiasts. New technology and the increased liberties in form resulted in the end of the era of dial telephones. The 1972 version of the phone, equipped with buttons in place of the rotary dial, never became as popular as its predecessor.

The Norwegian telephone 11AB22 introduced by Elektrisk Bureau in 1967 used the same shell as Dialog, but had different electronics. The 11AB22 was the world's first transistorized telephone, and unlike the Ericsson Dialog used an electronic ringer instead of bells, and was equipped with a dynamic microphone.

Due to the massive amount of telephones intended to be produced, uncommonly heavy emphasis was put on design. The exemplars for the future basic telephone of every home were Ericsson's own models from the 1930s. But the Dialog was to be modern, yet follow Ericsson's design tradition.

The handle was fitted in size according to the dimensions of an average face, which had been taken as the starting point of the design process. In the completed product, the distance between the transmitter (mouth piece) and the receiver (ear phone) was noticeably shorter than earlier models. The handle was made as light as possible to minimize the stress inflicted upon the wrist and blood veins of the speaker during long calls. The weight of the base unit was also minimized especially for shipping reasons. The dial finger wheel and face plate consisted of several parts and was designed so that it could be replaced with a set of buttons in a later version of the phone.

The depth and thoroughness of the design is perhaps best depicted by the fact that even the inner lighting of the phone was taken into account: the inside was not left completely dark, to avoid insects inhabiting the product.
