BARTEC is an interesting company. It describes itself as being the
best choice for police "telephone surveillance equipment." BARTEC's
product line is extensive, featuring "the intelligent choice for all
your telephone surveillance investigations - pen register, audio
wiretap or PCS/cellular." (http://www.bartec.com/products.html)
BARTEC products include:
* DLP-14/400 WIRELESS INTELLIGENT TRANSMITTER, described as a
"PCS/cellular intercept device designed for use by both law
enforcement and wireless companies for telephone surveillance
investigations." (http://www.bartec.com/content/wit.html)
* D A R E / DIGITAL AUDIO RECORDING ENVIRONMENT, described as a tool
for "streamlining and simplifying wiretap operations. This is
accomplished by taking advantage of the latest in digital audio
recording technology which automatically places both voice and data
together on CD-ROM." (http://www.bartec.com/content/whatshotDARE.html)
* C O P S / CALEA OPERATIONS, the recommended way for BARTEC customers
to perform surveillance under the controversial Communications
Assistance for Law Enforcement Act (CALEA), aka Digital Telephony law.
To summarize: COPS essentially links the telephone company with
police. COPS includes a dedicated PC, an 8-port Cisco router / modem
pool, and a 100 base T Hub. The protocol used to share info is called
J-025. (http://www.bartec.com/content/whatshotCOPS.html)
J-025 is more properly called J-STD-025, and was jointly developed by
the Telecommunications Industry Association and the Alliance for
Telecommunications Industry Solutions. It came out in December 1997
and soon became the focus of litigation, with privacy groups and some
industry groups saying it went beyond what Congress intended. The DC
Circuit agreed in part
(http://www.epic.org/calea/dc_cir_decision.html).
For more background, consider a report by a Telecommunications
Industry Association working group dated May 2000 that arose after a
meeting at the Excalibur hotel in Las Vegas. The document is here:
http://www.tiaonline.org/standards/CALEA_JEM/CJEM503-105.pdf
What's interesting is that the report, authored by Mark A. Montz, a
product architect at Compaq, talks up the benefits of open source
softwware as a way to keep the Feds honest -- in much the same way
that some of us have recommended the release of Carnivore's source
code.
Excerpt:
>The connection point may also allow access to data packets not
>authorized for surveillance to be collected as well as the ones
>covered by a subpoena. Also, while the PC/hard disk system above
>substitutes for a tape recorder, there is nothing currently
>equivalent to a "pen trace device". Indeed, one of the major concerns
>with the industry suggestion of delivering all the information to law
>enforcement agencies was that the agencies could not be trusted to
>discard data they were not authorized to receive. A novel solution to
>this problem may be possible by the success of a new concept: Open
>Source... A neutral organization such as UL Labs or some other agency
>would be responsible for downloading the software into the computer,
>and the delivering it to the law enforcement agency...

BARTEC's simple, affordable, intelligent solution for CALEA
intercepts!

Click here for a diagram of a typical COPS configuration.
What Is COPS?
CALEA Operations (COPS) is BARTEC's solution for the Communications
Assistance for Law Enforcement Act (CALEA) which will begin
implementation on June 1, 2000. COPS serves as the primary
interface for delivery of J-025 standard messages from the
Telecommunications Service Provider (TSP) to the law enforcement
agency (LEA), as defined in CALEA legislation. A COPS workstation
consists of:
BARTEC COPS Software
PC (configured for COPS specs)
8 Port Cisco Router / Modem Pool
100 base T Hub
How Does COPS Work?
A COPS workstation supports three critical tasks in the CALEA pen
register intercept environment, as follows:
1. CALEA "D" and "E" Interface
CALEA legislation defines "D" and "E" interfaces for telephone
surveillance. The "D" interface is located in the TSP switch or
regional facility. The "E" interface is located at the LEA. The
"D" interface will require a TCP/IP wide area network (WAN) to
be established between the TSP and the LEA. The WAN may be on a
dial-up or dedicated private lease line (PVC) that is defined
by the TSP or LEA. To meet interface requirements, the COPS
workstation includes a Cisco router with eight modem ports.
Modem ports one to seven are dedicated for "E" interface - one
for each TSP. Modem port eight is reserved for communication
with existing BARTEC devices for analog pen register
intercepts. Remote command and control and automatic downloads
for BARTEC's Micro DNR, SSL-12 Smart Slave and DLP-14/400
Wireless Intelligent Transmitter will be accessible via port
eight. This feature is not available on any other CALEA
intercept system, and will prove important and useful as
telephone surveillance makes the transition from analog to
digital over the next several years.
2. Data Compilation
In a CALEA pen register intercept environment, TSPs will
deliver J-025 standard messages, as defined in the CALEA
legislation, over a call data channel (CDC). Each of the modem
ports on the Cisco router supports CDC delivery of data in a
number of formats. Analog data received on port will be in
ASCII format. COPS assembles and converts all data in all
formats for compatibility with many different analytical
software packages.
3. Creation of Files and Distribution of Collected Data
Once data is assembled and converted, it is compiled into
files. Once files are created at the COPS workstation, data can
be distributed for analysis or other CALEA functions.
Distribution can take place via the LEA network to a secure
server, on a daily or periodic basis. Data may be loaded
manually or on demand to the server by the LEA network
administrator. Analysis software typically resides on the
server.
In a CALEA wiretap intercept environment, COPS will test J-025
messages received from the TSP to determine if immediate
distribution is required. Messages are routed through the LEA
network to the appropriate BARTEC Digital Audio Recording
Environment (DARE) workstation. At the DARE workstation, analog
voice and data will be assembled by the COPS Micro DNR for real
time access by the DNR. Why Buy COPS?
COPS offers multiple CALEA intercept capability and supports both
pen register and wiretap configurations
COPS can interface with BARTEC analog pen registers/remote
devices
as telephone surveillance transitions to CALEA
COPS offers future expansion to accommodate additional CALEA
interfaces
COPS is affordably priced, allowing even small law enforcement
agencies to perform CALEA intercepts
