HCFL/56
V.90/K56flex
PC Card Device Sets
for Host-Controlled, Low Power Applications
Conexant HCFL/56 PC Card Device Sets support high-speed
analog data up to 56 kbps, 14.4 kbps fax, voice/TAM, analog
cellular direct connect, and speakerphone (optional) operation
(Table 1). The modem supports ITU-T V.90/K56flex, V.34 and
V.32bis data modulations and is designed to operate with dial-up
telephone lines in the U.S. and worldwide. Low profile, small
PQFP/TQFP packages and low voltage operation with low power
consumption make this device set ideal for laptop, notebook, and
palmtop applications.
The device set consists of a PCMCIA bus interface device (L550211 PCMCIA BIF) in a 128-pin TQFP and a modem data pump
(MDP) in a 144-pin TQFP or 100-pin PQFP. Host modem software
is provided and the downloadable architecture allows updating of
MDP executable code.
The L5502-11 PCMCIA bus interface device supports two
peripheral channels, one channel for the modem and a second
channel for an optional user-defined function (Function 2).
In V.90/K56flex mode, the modem can receive data at speeds up
to 56 kbps from a digitally connected V.90- or K56flex-compatible
central site modem. Taking advantage of the PSTN, which is
primarily digital except for the client modem to central office local
loop, V.90/K56flex modems are ideal for applications such as
remote access to an Internet Service Provider (ISP), on-line
service, or corporate site. The modem can send data at speeds up
to V.34 rates.
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.42bis/MNP 5) maximize data transfer integrity and boost
average data throughput. Non-error-correcting mode is also
supported.
In V.32bis mode, the modem operates at line speeds up to 14.4
kbps.
In voice/TAM mode, enhanced 2-bit or 4-bit per sample ADPCM
coding and decoding at 7200 Hz sample rate allows efficient digital
storage of voice/audio. This mode supports applications such as
digital telephone answering machine (TAM), voice annotation, and
recording from and playback to the telephone line.

Description
General
The modem device set, consisting of separate
PCMCIA Bus Interface (L5502-11) and modem data
pump (MDP) devices, provides the processing core
for a complete modem design. The OEM adds BIF
crystal, discrete components, and a telephone
line/telephone/voice/-TAM/analog cellular interface
circuit to complete the modem system. Table 1
shows the supported functions by product family.
Dialing, call progress, V.80, telephone line interface,
voice/TAM, speakerphone, and analog cellular
phone interface functions are supported and
controlled through the AT command set. Connection
to the host/DTE is supported by the PC Card
interface (Figure 1).
For U.S. operation, the modem can operate with a 1relay data/fax/TAM DAA interface (Figure 2) or a 2relay data/fax/TAM/V.61/Speakerphone DAA
interface
(Figure 3).
Host Modem Software
The host modem software performs two distinct
tasks:
1. General modem control which includes
command sets, fax Class 1, voice/TAM,
speakerphone, error correction, data
compression, cell phone drivers, and operating
system interface functions.
2. Modem data pump control. Binary executable
code controlling MDP operation is downloaded
as required during operation. Signal processing,
including data and fax modulation and
demodulation, as well as voice sampling, is
performed in the hardware DSP.
Configurations of the modem software are provided
to support the modem models listed in Table 1.

Operating Modes
Data/Fax Modes
In V.90/K56flex data modem mode, the modem can
receive data from a digital source using a V.90- or
K56flex-compatible central site modem at line
speeds up to 56 kbps. Asymmetrical data
transmission supports sending data at speeds up to
V.34 rates. This mode can fallback to full-duplex
V.34 mode, and to lower rates as dictated by the line
conditions.
In V.34 data modem mode, the modem can operate
in 2-wire, full-duplex, asynchronous modes at line
rates up to 33.6 kbps. 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 33.6 kbps to 300 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 fax modem mode, the modem can operate in 2wire, 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.31 Fax Class 1.0, or Fax
Class 2 command interface. Full HDLC formatting,
zero insertion/deletion, and CRC
generation/checking are provided.
Synchronous Access Mode (SAM) – Video
Conferencing
V.80 synchronous access mode between the
modem and the host/DTE is provided for host-based
communication protocols, e.g., H.324 video
conferencing applications. Voice-call-first (VCF)
before switching to a videophone call is also
supported.
World Class Operation
W-class functions support modem operation in
multiple countries. Additional modem functions are
provided in areas such as dialing, carrier transmit
level, calling tone, call progress tone detection,
answer tone detection, blacklisting, and relay control.
Country dependent programmable parameters are
included in the .INF file for customization by the
OEM.
Voice/TAM Mode
Voice/TAM Mode features include 8-bit µ-Law, ALaw, and linear coding at 8000 Hz and 7200 Hz
sample rates. Tone detection/generation, call
discrimination, and concurrent DTMF detection are
also supported. ADPCM (4-bit IMA) coding is also
supported to meet Microsoft WHQL logo
requirements.
Voice/TAM Mode is supported by three submodes:
1. Online Voice Command Mode supports
connection to the telephone line or, for S models,
a handset.
2. Voice Receive Mode supports recording voice or
audio data input at the RIN pin, typically from the
telephone line or, for S models, a
microphone/handset.
3. Voice Transmit Mode supports playback of voice
or audio data to the TXA1/TXA2 output, typically
to the telephone line or, for S models, a
speaker/handset.
Speakerphone Mode (S Models)
The S models include additional telephone handset,
external microphone, and external speakerphone
interfaces which support voice and full-duplex
speakerphone (FDSP) operation.
Hands-free, full-duplex telephone operation is
supported in Speakerphone Mode under host
control. Speakerphone Mode features an advanced
proprietary speakerphone algorithm which supports
full-duplex voice conversation with acoustic, line, and
handset echo cancellation. Parameters are
constantly adjusted to maintain stability with
automatic fallback from full-duplex to pseudo-duplex
operation. The speakerphone algorithm allows
position independent placement of microphone and
speaker. The host can separately control volume,
muting, and AGC in microphone and speaker
channels.
Sleep Mode
Sleep Mode is supported in the modem device set.
