MOUNTAIN VIEW, Calif.-- February 6, 1989 -- Recognizing the market's
need for a high-speed modem that is compatible with today's universe of
dial-up modems, Telebit Corporation today introduced the industry's
first modem to provide full compatibility with CCITT V.32 and low-speed
modems as well as multicarrier PEP modems.
"High-speed connectivity has become critical for the long-term success
of businesses and institutions of all sizes," said Lewis F. Ellmore,
Telebit president and chief executive officer.  "For this reason,
organizations worldwide are seeking dial-up communication solutions that
allow them to transfer data at speeds greater than 9600 bps while
maintaining compatibility with V.32 modems and the installed base of
low-speed modems.  Telebit's T2500 PEP modem offers these organizations
the ultimate solution:  speed, connectivity and universal compatibility
in one cost-effective package."
The T2500 operates in both synchronous and asynchronous environments
and supports all major modem-industry standards.  It communicates with
other T2500 modems and the installed base of Telebit and other
multicarrier PEP modems at speeds up to 18,000 bps without data
compression and up to 19,200 bps with data compression.  When
communicating with V.32 modems, the T2500 supports error-free
transmission speeds up to 9600 bps with Trellis-Coded Modulation (TCM).
For organizations with low-speed connectivity needs, the T2500 offers
downward compatibility with CCITT V.22 bis, V.22, V.23, V.21 and Bell
212A and 103J modems, at speeds from 300 to 2400 bps. 
V.42 compatible, the T2500 supports error correction and data
compression through MNP Class 5 for speeds of 9600 bps and below.  At
higher speeds, the Telebit modem ensures data integrity with PEP 16-bit
CRC error-detection and control protocols and delivers data compression
using a Lempel-Ziv algorithm.
In addition to providing universal compatibility, the T2500 offers users
the connectivity benefits of Telebit's patented multicarrier PEP
technology.  Because Telebit's PEP (Packetized Ensemble Protocol)
technology enables the modem to take advantage of the entire bandwidth
of the telephone line rather than just one or two frequencies, the T2500
maintains connections on telephone lines that modems using conventional
technologies are not able to sustain.  The T2500--like all other PEP
modems--adjusts its transmission speed in 100 bps decrements when faced
with deteriorating lines, rather than halving its transmission speed as
do non-PEP modems.  As a result, the T2500 delivers throughputs over
ordinary telephone lines up to six times faster than possible with other
dial-up modems.
In asynchronous PEP mode, performance is maximized by providing
integrated support for UNIX UUCP, Kermit, Xmodem, Ymodem, and SNA/SDLC
file-transfer protocols.
With the T2500, users do not need to invest in new data communications
programs or modify their existing software.  The factory default
Conventional Command Mode allows the T2500 to be configured
automatically using any software that supports the Hayes V-series
command set, while Telebit's Enhanced Command Mode allows users to take
full advantage of the T2500's advanced features, such as remote
configuration management.
"The T2500 provides organizations a means to realize the benefits of
today's technology without putting their communications investment at
risk," said Ellmore.  "Telebit's software-defined architecture allows
future standards to be incorporated readily.
"Most important, Telebit's multicarrier technology continues to evolve
-- users can expect to see further significant performance increases.
In contrast, conventional, single-carrier technology has reached its
ceiling for speed."
The T2500 is available as a standalone unit or as a rackmount system
card, which can be installed in a Telebit T9000 rackmount system
chassis.  Each chassis holds up to 12 modem cards and mounts into a
standard 19-inch EIA rack for easy integration with other data
communications equipment.  An intelligent controller card permits local
or remote configuration, monitoring, control and testing of up to four
racks (48 modem cards) for system administration at a central site.
List price for both units is $1695.  Availability for the standalone
model is April 1989 for asynchronous functions and second quarter 1989
for synchronous functions.  Rackmount cards are available third quarter
Upgrades are available for the standalone and rackmount versions of
Telebit's TrailBlazer Plus, a 19,200 bps asynchronous modem.  Also
available are upgrades for the standalone and rackmount versions of the
T2000, a high-speed SDLC modem.
TrailBlazer Plus and T2000 standalone and rackmount card modems
purchased before January 1, 1989, can be upgraded for $795.  Upgrades
for TrailBlazer Plus and T2000 products purchased after January 1, 1989
will be available from Telebit for $395.  Upgrades must be pre-paid and
will require return to the factory.

			  SCO's Case Against IBM

November 12, 2003 - Jed Boal from Eyewitness News KSL 5 TV provides an
overview on SCO's case against IBM. Darl McBride, SCO's president and CEO,
talks about the lawsuit's impact and attacks. Jason Holt, student and 
Linux user, talks about the benefits of code availability and the merits 
of the SCO vs IBM lawsuit. See SCO vs IBM.
