Code Coördinatie Bureau · 1945-1960
- this page is a stub
Code Coordination Bureau (Dutch: Code Coördinatie Bureau), abbreviated CCB,
was the first post-WWII cipher authority of the Netherlands, established on 7
March 1945 in London by the Dutch Government in exile,
at the initiative of Colonel J.A. Verkuyl.
It was tasked with the coordination of the cipher facilities
and key material of all departments of the Dutch Government and the Dutch
armed forces. CCB was succeeded in June/July 1960 by the newly established
Nationaal Bureau voor de Verbindingsbeveiliging (NBV) —
the National Communications Security Agency).

Statistical analysis machine

This photograph shows the statiscical analysis machine from the left.
It comprises a horizontal panel or desk with integrated switches at the centre
and a large patch panel at the right. In front of the operator is a circuit
diagram. To his left is a
Siemens T-send-77 double tape reader.
The patch panel is at the right of the operator.
Towards the rear of the desk is a sloped panel with 40 electromechanical
counters, in a 10 × 4 arrangement, and two additional counters at the far left.
The counters are similar to the ones used in the
Erolet.
On the wall behind and above the machine is a rack with spare patch cables.

This photograph was probably taken the same day, and shows the machine from
a right angle. The circuit diagram and the patch panel are more clearly visible
in this image. The switch panel in front of the operator appears to be divided
in two sections: (1) an unknown number of switches at the left and (2)
a set of 40 switches in a 8 × 5 arrangement at the right.
It is possible that the two sections are separated by a column of five
indicator lamps.
To the left of the operator, behind the
Siemens double tape reader,
is a mechanical calculator.
