Rockwell Introduces Data/Fax/Voice/Business-Audio Modem

Rockwell International Corporation introduced the RCV144ACi-BA, a data/fax/
voice/business audio, 14.4 kbps modem device set designed to support
multimedia applications.  The chipset, which is the enabling silicon
technology for Rockwell's Integrated Communications System(tm) marketing
alliance, provides original equipment manufacturers (OEMs) with a
low-cost, high-performance solution for integrating communications and
audio into the desktop personal computer environment.

The RCV144ACi-BA is supported by the Rockwell High-Speed Interface (RHSI --
patent pending) Windows-compatible serial communications and Media Control
Interface (MCI) audio drivers.  These drivers overcome the limitations of
predefined UART speeds, allowing the modem device set to support data
throughput speeds of 200 Kbps and higher.

The integration of voice and audio has greatly expanded the capability and
functionality of what has become a commodity peripheral: the data/fax
modem. Users can now expect telephone functions within PC applications,
including a digital answering machine, voice mail, message retrieval and
message forwarding.

Rockwell's RCV144ACi-BA device set supports data and fax operation up to
14.4 Kbps; ADPCM 2-, 3- and 4-bit voice compression/decompression at 7200
hz and audio 8- and 16-bit record/playback at 11.025 Khz or 7200 hz.  The
microcontroller firmware performs extended AT commands providing V.42/MNP
2-4 error correction, V.42 bis/MNP5 data compression, MNP 10, EIA/TIA 578
Class 1 and Class 2 fax standards, Calling Number Delivery (Caller ID)
detect and voice and audio functions.

The RCV144ACi-BA modem device set consists of a single-package, 68-pin PLCC
data pump and a Rockwell 84-pin PLCC microcontroller with supporting
firmware.  Samples of the RCV144ACi-BA are available now and volume
production will begin January 1994.  Pricing for 10K quantities is $77.
