22 August 2006. Thanks to A for pointing.

Entering this in Google Search will list about 250 AT&T government-contract-related files:

site:www.att.com "www.att.com/gov/docs/"

Even though they are available through links on the AT&T site, most of the documents are covered by this notice:

RESTRICTION ON DISCLOSURE AND USE OF DATA This proposal includes data that shall not be disclosed outside the Government and shall not be duplicated, used, or disclosed — in whole or in part — for any purpose other than to evaluate this proposal. If, however, a contract is awarded to this offeror as a result of — or in connection with — the submission of this data, the Government shall have the right to duplicate, use, or disclose the data to the extent provided in the resulting contract. This restriction does not limit the Government’s right to use information contained in this data if it is obtained from another source without restriction. The data subject to this restriction are contained in all sheets that carry the legend: Use or disclosure of data contained on this sheet is subject to the restriction on the title page of this proposal.

This document contains confidential, trade secret; commercial or financial information owned by an AT&T Company and is submitted for evaluation purposes only. It is exempt from disclosure under the Freedom of Information Act (5 U.S.C. 552) under Exemption (b) (4), and its disclosure is prohibited under the Trade Secrets Act (18 U.S.C. 1905).

Several draft documents show material redacted in final copies. Compare, for example:

http://www.att.com/gov/docs/vol_2sec2d.pdf (redacted)

http://www.att.com/gov/docs/redacted2sec2e.doc (unredacted)

To find more of these look for similar file names in PDF or DOC (the names may differ slightly, as above).

Little of significance seems to have been redacted but competitors might find it useful.

Contracts can be located with this search term:

Among these a sub-directory of "legacysbccontracts" is notable for older contracts by SBC.

Nothing there appears to be related to the assistance allegedly being given to NSA, but perhaps sharp eyes can spot tie-ins.

Cryptome has archived the documents in case AT&T elects to hide them.

Related, and probably known to most telco researchers, a highly useful site is The Telecommunication Database:
