Introduction
The Rockwell RS56L-PCI (SoftK56) Host-Processed
V.90/K56flex™ Modem Device supports high speed
analog data up to 56 kbps, 14.4 kbps fax, voice/TAM,
cellular phone, and speakerphone (optional) operation.
The modem operates with PSTN telephone lines as well
as analog and digital cellular phones in the U.S. and
world-wide depending upon model and installed software
drivers. The modem models are listed in Table 1.
The modem is packaged in a single 144-pin thin quad flat
pack (TQFP) that combines the PCI Bus Interface (BIF)
and Line/Voice Codec (LVC) functions. Figure 1 identifies
the major hardware signal interfaces supported by each
model.
Host modem and cellular phone driver software is
provided.
Operating with +3.3V power, this device set supports 32-
bit host applications in such cellular-based mobile designs
as laptop, notebook, and palmtop computers. The device
is easily integrated into PCI Bus-based embedded
motherboards, system boards, or plug-in cards.
Modem data pump and controller functions, traditionally
enabled using dedicated hardware, are processed in a
Pentium MMX-compatible CPU using host-signal
processing modem software.
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), on-
line 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 A-
Law, µ-Law, or linear coding at 8000 or 7200 Hz sample
rate to support applications such as digital telephone
answering machine (TAM) and voice annotation.
The SP model also 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.
Cellular phone operation is supported by a generic
hardware interface meeting multiple standards and host
software specific to a particular cell phone type.
Reference designs are available to minimize application
design time and costs.
