LAN/Soft V.92 Data/Fax Modem Combo with Integrated Physical Layer Device Set Product Summary
101884B
Conexant
3
Overview (Continued)
In V.34 data mode, the modem operates at line speeds up to
33.6 kbps.
Data compression (V.44/V.42 bis/MNP 5) and error
correction (V.42/MNP 2-4) modes are supported to
maximize data throughput and data transfer integrity. V.44 is
a more efficient data compression than V.42 bis that
significantly increases downstream throughput thus reducing
the download time for the types of files associated with
Internet use, such as Web pages and uncompressed data
such as in graphics, image, audio, and document files. V.44
data compression can achieve compression rates of more
than 25% over V.42bis. Typical compression ratio for V.44
on Web type data is approximately 6-1 resulting in overall
effective data throughput rate up to 300 kbps for a 56-kbps
connection. Non-error-correcting mode is also supported.
Conexant's SmartDAA 3 technology also offers the following
advantages over discrete and other silicon DAAs:
Incorporating Conexant’s proprietary DIB design (patent
pending) and other innovative DAA features, the
SmartDAA 3 architecture simplifies application design,
minimizes layout area, and reduces component cost for
worldwide support.
The SmartDAA 3 architecture eliminates the need for a
costly line transformer, relays, and opto-isolators
typically used in discrete DAA (Data Access
Arrangement) implementations. Product
implementation is also simplified by eliminating the
need for country-specific board configurations enabling
worldwide homologation of a single modem board
design.
The SmartDAA 3 system-side-powered DAA operates
reliably without drawing power from the line and
operates on long loops and poor line conditions.
The SmartDAA 3 uses a fully differential digital interface
which provides robust performance in the presence of
common mode noise.
Many SmartDAA 3 functions are software configurable
providing a flexible solution to often changing
worldwide regulations.
Enhanced features, such as monitoring of local
extension status without going off-hook, are also
supported.
For over a decade, Conexant has assisted customers
with DAA technology and homologation. This expertise
and system level approach has been leveraged in this
product.
Remote audio recording and remote audio playback
over the telephone line interface is supported using A-
Law,
μ
-Law, or linear coding at 8000 Hz sample rate to
support applications such as digital telephone
answering machine (TAM) and voice annotation.
Fax Group 3 send and receive rates are supported up to
14.4 kbps with T.30 protocol.
V.80 synchronous access mode supports host-
controlled communication protocols, e. g., H.324 video
conferencing.
Mini-PCI and PCI reference design kits are available to
minimize application design time and costs.
