N 1002 Type
This, the most modern and improved automatic table telephone is embodied in a moulded Bakelite case.
The design is distinctive and pleasing and incorporates a form of cradle or micro-telephone rest which is not readily damaged.
The interior apparatus including a magneto bell is mounted on a frame which can be removed as a unit, so that the sets are self-contained.
There is a sliding instruction tray with directory pad accommodation combined in the base plate. Pads are easily inserted and are included only when ordered.
The reception and transmission efficiencies of the Bakelite micro-telephone with inset transmitter and detachable receiver are vastly superior to the solid-back type, and the anti-side-tone induction coil in the circuit reduces the reproduction of extraneous noises and side-tone to a minimum. Terminal blocks have raised ribs to minimise surface leakage.
If required, a radio interference suppression unit can be supplied, for which provision for fitting exists in each set.
This telephone is normally produced in black, but if specially ordered it can be supplied in Chinese Red, Ivory or Jade Green.
N1002A27T was supplied in a Mottled Walnut finish.
Instruments can also be obtained without the sliding tray fitment.

How to convert a N1002H54T to work in the UK (Diagram N56352)
This conversion requires a UK Telephone Line Cord, a 3.3K Resistor and a Rectifier Element.
Ericsson made the N1002 in many variants. The basic telephone was the same but there were minor modifications made to suit different customers.
An unusual model is the N1002K25 shown here which was supplied to the
Australian Post Office as their 332AT
. Note the carrying handle.
