Industry's Broadest Portfolio of Modems
Enabling Integrated Communications for
Fax Machines and MFPs
Conexant leads the industry by offering the broadest family of fax
modem products available today. Offering high performance, fully
featured fax and MFP solutions, Conexant allows OEMs to design
products for the emerging integrated communications markets.
Fax machines are undergoing a transformation to an integrated
communication resource center -- combining fax with the telephony
features expected in consumer products. Conexant's fax modem
solutions enable manufacturers to address the growing market for
fax-ready devices, from high performance office products to low-cost
consumer applications.
Conexant continues to advance fax technology with the latest
levels of performance including integrated data modes now up to
33.6 Kbps and new features such as Automatic Speech Recognition.
These innovations are driving new products both for traditional fax
applications as well as completely new consumer functions such as
Internet fax and color fax.
Today the fax market is evolving into two different classes of
devices: PCconnected multifunction peripherals and telephony-
centric resources. For decades Conexant has played an integral
role in modern data communications, and the company's chipsets
are found in the majority of the world's fax machines. This
unmatched track record in fax innovation enables Conexant to lead
collaborative efforts with manufacturers in developing new products
for years to come.

Fax Modems
FM336 V.34 High Performance
Fax Modem
End users have come to expect higher performance,
particularly higher data rates, with each new genera-
tion of fax-ready products. Conexant's new FM336
V.34 high performance fax modem amplifies this
trend with transmit and receive times up to three and
a half times faster than a 9,600 bps (V.29) fax
machine.
The high performance of 33.6 Kbps has become the
standard for office automation. Led by Conexant's
design advances, the greater speed of V.34 is
migrating downward and penetrating the low-cost
fax-enabled machines that are ideal for small and
home office (SOHO) and consumer markets.
The FM336 fax modem is the first in a family of
high-speed devices that herald the next generation
of image transmission applications such as color fax
and Internet fax.
FM336 Distinguishing Features:
· Highly integrated, 100-pin TQFP single-chip solution
· V.34 half-duplex design specifically to provide
high data rates on all types of local loops
· Automatic Rate Adaptation and symbol rate
selection to optimize throughput speed
· PLL (Phased Lock Loop) technology uses a low
crystal frequency (28.224 MHz) reducing system
cost and EMI emissions
· Data mode support (V.34) for integrated
Internet connectivity
FM209 and FM214 MONOFAXTM Modem
Conexant's MONOFAX modem family offers
the greatest level of voice and speech features
integrated into a single fax modem device available
for OEMs today. This gives customers maximum
flexibility in product differentiation while utilizing
a single-platform design to reduce product
development time and system cost, and increase
manufacturing efficiency.
The single-package 128-pin TQFP, FM209 and
FM214 devices, which support fax transmission
and reception up to 14.4 Kbps, are pin-compatible
within the product family. This single-platform
design provides OEMs the flexibility to easily
incorporate additional features including full duplex
speakerphone and Digital Telephone Answering
Machine, conversation recording and message
playback capabilities during speakerphone
operations as well as Type I and Type II Caller ID.
This fax modem family offers software compatibility
across previous, popular generations of Conexant fax
modems including EFXL, DFXL and RFX series.
FM209/FM214 Distinguishing Features:
· Choice of speeds (9.6 Kbps and 14.4 Kbps)
along with voice and speech features
· First fax modem to offer Automatic Speech
Recognition technology
· Single motherboard design by combining
popular features of previous fax modems into
one pin-to-pin compatible package
p e r s o n a l i m a g i n g p r o d u c t s
· Full duplex speakerphone and V24 digital telephone answering
machine with 24 minutes voice recording capability
· Concurrent speakerphone and digital telephone answering
machine operation
Automatic Speech Recognition
Conexant is the first to offer Automatic Speech Recognition (ASR)
in the FM209/214 MONOFAX family for applications addressing a
range of markets -- from low-end stand-alone fax machines to
high-end products. Fax machines and multifunction peripherals
are integrating more features every year to add value for the end
user. But these new functions make the keypad interface more
complicated and difficult to use. For instance, the advent of
Internet faxing will lead to larger alphanumeric keyboards and
long URLs for Internet fax addresses. Automatic Speech
Recognition can help the user operate the machine without
the complicated keyboard functions, or even remotely from
a common phoneline.
Conexant's ASR technology demonstrates high speech
recognition accuracy, as well as a flexible vocabulary for menu
functions. Possible implementations of ASR technology for fax
and MFP devices include command and control of fax functions,
managing voice calls and phoning directories, managing and
reviewing voicemail. With its value-added potential, Automatic
Speech Recognition can be used as a key differentiator for
OEMs. Moreover, a simplified, intuitive interface increases
end user satisfaction.
What is a Fax Modem?
Fax technology is diverging into two separate classes
of devices: multifunction peripherals (MFPs) and
fax phones. MFPs are fax-enabled products that are
connected to a host PC, while fax phones are the
traditional standalone fax machines. As fax technology
improves, features and capabilities that were once
found only on high-end and mid-volume machines are
migrating downward. Multiple features including
speakerphone, answering machine, Caller ID, cordless
phones and Automatic Speech Recognition will become
a part of every standalone fax machine -- evolving into
the fax-ready integrated communication resource.
Despite all the various new document-messaging
methods -- email, Internet, intranets -- market research
confirms that the fax-enabled products remain the key
communications tool in Fortune 500 and mid-size
companies. The standalone fax machine continues to
be extremely popular because of reliability, familiarity
and ease of use, universal compatibility and speed in
delivering information and generating responses.
Within a standalone fax machine, Conexant offers a
complete system solution referred to as the FaxEngineTM
-- including a fax controller and a fax modem. The fax
controller acts as the "brain" managing and directing the
appropriate processing for fax, copy, print and scan
activities. Fax modems are similar to data modems
in structure, but implement different algorithms to
optimize performance, and are governed by different
ITU standards.
Conventional fax modems support ITU V.27ter,V.29 and
V.17, while higher performance fax modems support
V.34fax. In addition, fax modems support ITU standard
V.21 Ch2 for standard G3 fax handshaking (connections)
as well as the tone generation required to complete
the handshake.
