Cryptome would welcome a copy of this standard. Send to jya@pipeline.com or to John Young, 251 West 89th Street, New York, NY 10024.
The purpose of NIJ Standard 0227.00 is to establish functional, performance, interface, and documentation requirements for the digital intercept systems developed for use by law enforcement agencies for interception and evidence gathering on basic rate access ISDN lines.
The digital intercept system provides the capability to intercept any voice or digital data traffic between a subscriber and an associate and forward it to a central collector station for decoding and processing. The system is modular, consisting of one or more bridges (one for each subscriber line to be intercepted), and a central collector facility. The bridges intercept and forward all traffic from both directions on the subscriber's line to the central collector over leased forwarding facilities. At the central collector, a workstation for each monitored line provides an agent with control of the intercept process. Voice is made available for headphone monitoring and analog tape recording; minimization capability is provided to limit data retention to that with evidentiary content. Digital messages are stored on separate media for later retrieval and review. Facsimile messages are routed to a processor port for analysis by an external device.
The standard was developed under the sponsorship of the National Institute of Justice (NIJ). The project began when NIST/OLES entered into an interagency agreement with the Federal Bureau of Investigation to provide technical guidance for developing ISDN intercept methodologies. After the technology was successfully demonstrated the preparation of the performance standard was undertaken. The standard is now available on a CD-ROM. The CD has been recorded in Adobe Portable Document Format (PDF). Reader software for viewing PDF files is included on the CD for Windows 95/98/NT and Macintosh Systems.
The standard bears a FOR OFFICIAL USE ONLY classification, meaning it may be disclosed only to members of the law enforcement community and those in private industries supporting law enforcement activities. Please submit the request on your company letterhead. There is no charge for the standard, but only written requests can be honored. Send requests for this CD-ROM to A. George Lieberman, Ph.D., National Institute of Standards and Technology, 100 Bureau Drive, Stop 8102, Gaithersburg, MD 20899-8102.
