Introduction
Features
The Conexant RH56D-PCI V.90/K56flex Host
Controlled Modem Device Family supports high speed
analog data up to 56 kbps, 14.4 kbps fax, voice/TAM, and
speakerphone (optional) operation. The modem operates
with PSTN telephone lines in the U.S. and world-wide.
The modem is available with or without speakerphone
support (see Table 1).
The modem is packaged in a single 144-pin thin quad flat
pack (TQFP) that combines PCI Bus Interface (BIF) and
Modem Data Pump (MDP) functions. This modem is pincompatible with the SoftK56-PCI modem, part number
R6793 (see SoftK56-PCI data sheet Order No. MD231).
Host modem software is also provided.
Operating with +3.3V power, this device set supports 32bit host applications in such designs as embedded
motherboards and PCI half cards. Downloadable
architecture allows updating of MDP executable code.
In ITU-T V.90/K56flex data mode, the modem can receive
data at speeds up to 56 kbps from a digitally connected
V.90 or K56flex-compatible central site modem. A
V.90/K56flex modem takes advantage of the PSTN which
is primarily digital except for the client modem to central
office local loop and is ideal for applications such as
remote access to an Internet Service Provider (ISP), online service, or corporate site. In this mode, the modem
can transmit data at speeds up to V.34 rates.
In V.34 data mode, the modem operates at line speeds up
to 33.6 kbps. When applicable, error correction
(V.42/MNP 2-4) and data compression (V.42 bis/MNP 5)
maximize data transfer integrity and boost average data
throughput. Non-error-correcting mode is also supported.
All models support remote audio recording and remote
audio playback over the telephone line interface using ALaw, µ-Law, or linear coding at 8000 or 7200 Hz sample
rate to support applications such as digital telephone
answering machine (TAM).
The SP model supports position independent, full-duplex
speakerphone (FDSP) operation.
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.

provided.
Description
General
The RH56D-PCI modem provides the processing core for
a complete system design featuring data/fax modem,
voice/TAM, and speakerphone support, depending on
specific model (Table 1).
Synchronous Access Mode (SAM) - Video
Conferencing
Note: The term, “RH56D-PCI Device Set”, refers to the
family of modem models listed in Table 1.
Modem operation, including dialing, call progress,
telephone line interface, telephone handset interface,
audio interface, and host interface functions are supported
and controlled through the command set.
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.
Voice/TAM Mode
The modem hardware connects to the host processor via
a PCI Bus interface. The OEM adds a crystal circuit,
EEPROM, telephone line interface, telephone handset
interface (optional), and audio interface (optional) to
complete the system.
Host Modem Software
Voice/TAM Mode features include 8-bit µ-Law, A-Law, 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.
The host modem software performs two distinct tasks:
Voice/TAM Mode is supported by three submodes:
1.
1.
Online Voice Command Mode supports connection to
the telephone line or, for the SP model, a handset.
2.
Voice Receive Mode supports recording voice or
audio data input at the RIN pin, typically from the
telephone line or, for the SP model, 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 the SP model, a
speaker/handset.
2.
General modem control which includes command
sets, fax Class 1, voice/TAM, speakerphone, error
correction, data compression, and operating system
interface functions.
Modem data pump control. Binary executable code
controlling MDP operation is downloaded as required
during operation.
Configurations of the modem software are provided to
support modem models listed in Table 1.
Binary executable modem software is provided for the
OEM.
Speakerphone Mode (SP Model)
Data/Fax Modes
As a V.90/K56flex data modem, the modem can receive
data from a digital source using a V.90- or K56flexcompatible central site modem over the digital telephone
network portion of the PSTN 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.
As a V.34 data modem, 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 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.
The SP model includes additional telephone handset,
external microphone, and external speaker 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.
In fax modem mode, the modem can operate in 2-wire,
half-duplex, synchronous modes and can support Group 3
facsimile send and receive speeds of 14400, 12000,
9600, 7200, 4800, or 2400 bps. Fax data transmission

Notes:
Operating voltage: VDD = +3.3V ± 0.3V.
Test conditions: VDD = +3.3 VDC for typical values; VDD = +3.6 VDC for maximum values.
For all modes, +3.3V is supplied to BIF and MDP.
Definitions:
PCI Bus Power
On: PCI Bus +5V and +3.3V on (modem normally powered by +3.3V from PCI Bus +3.3V
or regulated down from PCI Bus +5V); PCIRST# not asserted.
Off: PCI Bus +5V and +3.3V off (modem normally powered by +3.3V from Vaux or Vpci); PCIRST# asserted.
PCI Clock (PCICLK)
Running: PCI Bus signal PCICLK running;
Stopped: PCI Bus signal PCICLK stopped (off).
Line connection:
Yes: Off-hook, IA powered.
No: On-hook, IA powered down.
Device States:
D3: Low power state. Suspend state can change the system power state; the resulting power state depends
on the system architecture (OS, BIOS, hardware) and system configuration (i.e., other PCI installed cards).
D0: Full power state.
Device and Bus States: D0, B0:
Any PCI transaction, PCICLK running, VCC present.
D3, B1:
No PCI Bus transactions, PCICLK running, VCC present.
D3, B2, B3: No PCI transactions, PCICLK stopped, VCC may be present.
D3, B3:
No PCI transactions, PCICLK stopped, no VCC.
Refer to the PCI Bus Power Management Interface Specification for additional information.
