Proprietary Information
Data/Fax Modes
In V.90/K56flex data modem mode, the modem can
receive data from a digitally connected central site
modem (CSM) at line speeds up to 56 kbps.
Asymmetrical data transmission supports sending
data up to V.34 rates; this mode can fallback to full-
duplex V.34 mode, and to lower rates as dictated by
line conditions.
In V.34 data mode, the modem operates at line
speeds up to 33.6 kbps. Error correction (V.42/MNP
2-4) and data compression (V.42 bis/MNP 5)
maximize data transfer integrity and boost average
data throughput up to 230.4 kbps. Non-error-
correcting mode is also supported.
Data modem modes perform complete handshake
and data rate negotiations. Using V.34 modulation to
optimize modem configuration for line conditions, the
modem can connect at the highest data rate that the
channel can support from 33600 bps down to 2400
bps with automatic fallback. Automode operation in
V.34 is provided in accordance with PN3320 and in
V.32 bis in accordance with PN2330. All tone and
pattern detection functions required by the applicable
ITU or Bell standard are supported.
In V.32 bis mode, the modem operates at line
speeds up to 14.4 kbps.
In V.22 bis fast connect mode, the modem can
connect at 2400 bps with a very short training time,
which is very efficient for small data transfers.
In fax modem mode, the modem can operate in 2-
wire, half-duplex, synchronous mode and can
support Group 3 facsimile send and receive speeds
of 14400, 12000, 9600, 7200, 4800, and 2400 bps.
Fax data transmission and reception performed by
the modem are controlled and monitored through the
EIA/TIA-578 Fax Class 1, T.30 Fax Class 1.0, or Fax
Class 2 command interface. Full HDLC formatting,
zero insertion/deletion, and CRC
generation/checking are provided. Both transmit and
receive fax data are buffered within the modem. Data
transfer to and from DTE is flow controlled by
XON/XOFF and RTS/CTS.
Synchronous Access Mode (SAM) - Video
Conferencing
V.80 Synchronous Access Mode between the
modem and the host/DTE is provided for host-
controlled communication protocols, e.g., H.324
video conferencing applications.
Voice-call-first (VCF) before switching to a
videophone call is also supported.
Worldwide Operation
The modem operates in US/Japan/Canada/TBR21
and other countries. Country dependent parameters
for functions such as dialing, carrier transmit level,
calling tone, call progress tone detection, answer
tone detection, blacklisting, and relay control are
programmable by ConfigurACE II for Windows.
SmartDAA technology allows a single PCB design
and single BOM to be homologated worldwide.
Advanced features such as digital PBX protection
are also supported.
TAM Mode
TAM Mode features include 8-bit
μ
-Law, A-Law, and
linear coding at 8 kHz sample rate. Full-duplex voice
supports concurrent voice receive and transmit.
Tone detection and generation, call discrimination,
and concurrent DTMF detection are also supported.
ADPCM (4-bit IMA) coding is supported to meet
Microsoft WHQL logo requirements.
TAM Mode is supported by three submodes:
1. Online Voice Command Mode supports
connection to the telephone line or, for the S
model, a handset.
2. Voice Receive Mode supports recording voice or
audio data input from the telephone line or, for
the S model, a microphone/handset.
3. Voice Transmit Mode supports playback of voice
or audio data to the telephone line or, for the S
model, a speaker/handset.
