TR1034™ Fax Boards
Series Fax Cards – Security
Secure Network Fax Servers with the Brooktrout TR
Series of Intelligent Fax Boards
Brooktrout Technology is a leading supplier of intelligent fax boards and media
processing hardware that enables the development of LAN Fax applications. Brooktrout’s market leading TR series of intelligent fax boards, the
TruFax and TR1034 series, provides small, medium and enterprise customers with an
efficient, centralized communications server that enables the electronic
delivery and receipt of documents. This centralized communications server,
known as ‘Network Fax’, typically requires the fax boards to be installed in
a server that is on the network. Network Fax servers save a company time
and money in terms of reduced labor costs and improved productivity.
Just like any other product connecting into their network, IT Professionals
should inquire to the risk of someone breaking into the network through the fax
server. Fortunately for IT professionals installing an analog, BRI,
digital T1/E1 PRI or IP based Brooktrout TR series intelligent fax board,
security on the network fax server is not an area of concern. This is
because the TR series of intelligent fax boards from Brooktrout transmit
information only via the T.30 or T.38 fax communication protocols. T.30
and T.38 are both fax protocols that describe the overall procedure
for establishing and managing communication between two fax devices. T.30 is a
PSTN based protocol that covers 5 phases of a fax procedure, which are the
call set up, communication mode selection, message transmission, post message
procedure, which includes end-of-message and confirmation, and call release, or
disconnection. T.38 is an IP based protocol that closely inter-works with
T.30 to enable these same procedures over IP in real-time.
Neither T.30 or T.38 allow for the processing of data or the transmission of
data1. Both protocols only
allow for the transfer of T.4 and T.6 fax images. For example, if a
malicious packet was sent over IP to a Brooktrout TR1034 series intelligent fax
board, the on-board processing will immediately recognize the non-T.38 packet
and drop it. If it is not a valid T.30 or T.38 packet, there is no
communication path to the network.
Data modems, on the other hand, support both the V.90 and V.92 protocols, which
are 56 kbps data transfer standards and have data exchange capability. The
fact that a data modem allows the transfer of data, and not just fax images like
a Brooktrout intelligent fax board, makes a network very susceptible to security
breaches by would be hackers.
In addition to this, Brooktrout intelligent fax boards are also secure from
files being passed using Binary File Transfer, or BFT. Brooktrout’s TR
series boards permits the BFT protocol to be disabled within the application by
the administrator at the time of install. Consequently, having a TR series
board in a server that's on the network poses no threat whatsoever to your
The TruFax and TR1034 series of intelligent fax boards
from Brooktrout Technology provide safe, secure and reliable fax transmission
capability. Through the use of the T.30 and T.38 industry standards,
Brooktrout TR series fax boards transmit images in the same manner that two fax
machines would send an image to each other. This use of standards combined
with the ability to turn off Binary File Transfer, ensures that installing a
Brooktrout intelligent fax board on your network poses no greater security
threat than plugging a standalone fax machine into an analog telephone jack.
1 With the exception of
Binary File Transfer (BFT) mode. Brooktrout’s TR1034 fax over IP
solution does not support BFT. Other Brooktrout products that do
support BFT allow this feature to be disabled. With BFT disabled, only
fax protocol and compressed images will be allowed.
