2. ASAE will process high-grade systems on1y to the extent 

necessary to isolate such systems from the total traffic receipts in 

order to exploit low, medium-grade, and und:i.agnosed traffic. Undiagnosed traffic is defined as any trafflc not bearing the characteristics 

of designated systems.

l~. ASAE ma.y conduct cryptanalytic processing jointly wi l;h NSA on 

undiac;nosed traffic. When o. determination is subsequently mude by NSA 

that any portion of such traffic is high-grade, ASAE will. immediately 

cease vrork. on those portions so detemined. 

5. ASAE wil.l. keep NSA informed of aJ.]_ cha.naes in encipherment in 

the systems for which ASAE has operational. responsibility. Notification 

of routine encipherment changes for which solution has been effected 

at ASAE will be accompanied by a nm"lll number of representative messages. 

When o. change in enciphermcnt occurs in a system for which ASAE has 

responsibility but for which a solution co.nuot be effected 'fl.thin twentyfour hours, ASAE 1rill forward all U.S. inl.ercept in that system to NSA 

by electrical means until a solution is effected or until a major change 

has been diagnosed. J\.Sl\E ma.y continue to perform analysis on such 

systems involved unless i"t; is determined by NSA that the systems are 

high-grade. 

6~ responsible for determining the appropriate grade level 

of all L___J systems. 

~ NSA i.····s solely responsible for all cryptanalytic effort on those 

L___Jsystems diagnosed as high-grade. 

8. NSA is responsible for periodic re-diae;noses of' systems 

desie;nated as high-grad.e in order to validate the grade level or those 

systems .on a current basis. Should any low or medium-grade system be 

isol~t~.Q. __ trt?Jll_t~~~~?:.~ ~~giJ)aJ.ly designatQd_h!Bh-grade, NSA will. delegate z:.espons:i.bility for that system to ASAE. 

9. NSA will perf'orm such cryptanalytic processing ot low and 

medium-grade systems as is necessary for purposes of technica.1 control 

and technical support, forwarding results of such processing to ASAE on 

a timely·. basis •

of high intelligence value will be forwarded by electrical means. Those

it is essential that discrimination be used in the selection of material 

for forwarding by electrical means or by bag. While it is imperative

Format: 

Each TA.SUM will consist of' two sections: 

SECTION I - GENERAL CCMmN'lB 

Information contained in this section sbou1d include remarks and/or 

questions of' a general. nature including unit identification, location,

keys, address groups, procedures references, unique external indicators, 

possible reorge.nization, etc. 

Callsigns: When callsigns change, the new callsigns and 

frequencies shall be reported in following TAStMS with any continuities
