Import and Export (Strategic Commodities) Regulations

[1988 Ed.

[Subsidiary]

(a) Error detection or correction algorithms in "main storage"; (b) The interconnection of two "digital computers" so that, if the active central processing unit fails, an idling but mirroring central processing unit can continue the system's functioning; (c) The interconnection of two central processing units by data channels or by use of shared storage to permit one central processing unit to perform other work until the second central processing unit fails, at which time the first central processing unit takes over in order to continue the system's functioning, or (d) The synchronization of two central processing units by "software" so that one central processing unit recognizes when the other central processing unit fails and recovers tasks from the failing unit.

(i) Not used.

(j) "User-accessible microprogrammability":

Note:

For the purpose of this sub-item, "digital computers" and "related equipment" are not considered to be designed or modified for "user-accessible microprogrammability" if this facility is limited to: (a) Loading, reloading or inserting of "microprogrammes", provided by the supplier; or (b) Simple loading of "microprogrammes", which may or may not be provided by the supplier, but which are neither designed to be accessible to the user nor accompanied by training or "Software" for user accessibility.

(k) "Data (message) switching"; (l) "Stored programme controlled circuit switching"; or (m) "Wide area networks";

(i) Having the following characteristics:

(a) Size, weight, power consumption and reliability or other characteristics (e.g. bubble memory), which allow easy application in mobile tactical military systems; and (b) Ruggedized above the level required for a normal commercial/office environment, but not necessarily up to levels specified in sub-item (l);

(2) Except

(i) "Digital computers" or "related equipment" therefor, provided:

(4) They are "embedded" in other equipment or systems;

Note:

This does not preclude input/output control unit-disk drive combinations having all the following characteristics: (1) A "total transfer rate" not exceeding 5.5 million bit per second; (2) Total connected "net capacity" not exceeding 200 million bit; (3) No more than one independent drive; and (4) A "total access rate" not exceeding 40 accesses per second;

(b) They are not the "principal element" of the other equipment or systems in which they are "embedded"; (c) The other equipment or systems are not described by other Items in these Lists; (d) They have been designed and used for non-strategic applications; (e) They are, by nature of design or performance, restricted to the particular application for which they have been designed; (f) The "total processing data rate" of any one "embedded" "digital computer" does not exceed 43 million bit per second;
