Rooms so that messages of a broken key are not overlooked, undertaking
"key" and "dud" analyses as explianed in German Traffic Analysis in
Sixta, see pp. 56 and 58, and providing general W/T.I. information
for cryptographers. These functions all depend upon T.A. knowledge
and are frequently accomplished by methods born of T.A.
One of the most strenuous obligations of the Fusion Room is
liaison with the Traffic Identification Section in Hut 6. Many times
each day discoveries are made or questions arise in both offices
which require direct consultation between them. Furthermore the
processes and purpose of both offices have so many points of similar-
ity that the division of labor is a hinderance rather than an aid.
For these reasons, it is submitted that the unification of
those offices whose function are preliminary and susequent to
cryptography is desirable. Either the Fusion Room should move into
T.I.S. or T.I.S. into the Fusion Room. Their separation is simply
the result of the way they came into being. Their continued sepera-
tion is contrary to the rational direction of the development of
T.A.-Cryptography-Intelligence towards operational unification.
These observations have a direct reference to the German problem
as it is undertaken at B.P., however, they may be understood in
reference to any similar T.A.-Cryptography-Intelligence problem,
either in war or peace.
