Subject: Revised New Courier Press Release
U.S. ROBOTICS ADDS SEVEN NEW PRODUCTS TO COURIER MODEM
LINE; PRODUCTS OFFER 10 NEW FEATURES INCLUDING 21.6 KBPS
CONNECT SPEED
New Courier Modems Offer Host of New Features Including V.32 terbo, HST
Cellular, V.17, Security; Products to Ship September 1, 1993
SKOKIE, Ill. -- August 23, 1993 -- U.S. Robotics, Inc. today announced a major
evolution to its Courier modem line; the company will ship new Courier models
beginning September 1 that include a battery of new features, most notably the
19.2 Kbps V.32 terbo protocol and U.S. Robotics' proprietary Adaptive Speed
Leveling (ASL[tm]) technology, which further boosts speed to 21.6 Kbps. The
new features fall into three broad categories: increased data rates, fax
enhancements and high-end features. The company is offering an upgrade
program for current Courier high-speed modem users, also beginning
September 1.
U.S. Robotics Among First To Ship V.32 terbo
Among the features included in the new modems is V.32 terbo, a new protocol
for 19.2 Kbps data transmission developed by AT&T; Courier modems will be
among the first shipping products to include V.32 terbo, which delivers a 33
percent increase in speed over the 14.4 Kbps V.32 bis standard. The move to
V.32 terbo is in keeping with U.S. Robotics' philosophy of developing modems
that support a variety of protocols and provide compatibility with a wide
range of modems from other vendors.
These products allow Courier customers to take advantage of increased data
rates, while still assuring them of a clear upgrade path to the forthcoming
V.fast standard. Additionally, the new modems provide Courier customers the
added benefit of proprietary technology that boosts connect speed to 21.6 Kbps.
Proprietary ASL Increases Speed to 21.6 Kbps; DTE Interface Rate Jumps to
115.2 Kbps
The Courier V.32 terbo modems include the company's proprietary Adaptive
Speed Leveling (ASL[tm]) protocol, boosting throughput to 21.6 Kbps, a 50
percent increase in speed over the current 14,400 bps V.32 bis standard. This
protocol allows users who are connecting two Courier modems to take
advantage of the 21.6 Kbps rate; V.42 bis data compression provides an
additional increase in throughput. An increased DCE to DTE (modem-to-
computer) interface rate of 115,200 bps and faster processors accommodate
these higher speeds.
Courier Modems Still Upgradable to V.fast (ITU-T V.34)
The new Courier modems, like the current Courier high-speed models, will be
field upgradable to the forthcoming V.fast standard, which will likely be named
V.34. Availability will depend on ITU-T progress in finalizing the standard;
however, study group approval of V.34 is expected in June, 1994. The standard
will provide data rates of up to 28,800 bps.
Dale Walsh, U.S. Robotics vice president, advanced development, and a
member of the ITU-T committee developing the V.34 standard, points out that
V.32 terbo should not be confused with the V.fast standard. "The V.32 terbo
protocol is really an extension of V.32 bis," said Walsh. "In fact, when you
compare the processing power necessary to run V.32 terbo and V.34, the
processors in V.32 terbo modems are more like the processors used for V.32 bis
-- they are certainly not capable of achieving the 28.8 Kbps throughput that
will be available with V.34."
U.S. Robotics' upgrade to V.34 is performed via a daughterboard swap, which
takes a typical user about five minutes. Because the pending V.34 standard
requires two to three times the processing power of V.32 bis, both the hardware
and software must be upgraded to provide enough power and ensure that there
are no hardware bottlenecks that might impede the speed of V.34.
Upgrades to New Product Available for Current Courier Users
Current Courier users may upgrade to the new models. Pricing will vary
depending on the modem model being upgraded. The upgrade program will
include both current-model Courier modems, which may be upgraded via a
daughterboard swap, as well as older-model Courier modems, which may be
exchanged for the new models. Courier 2400 bps modems are not included in
the upgrade program.
New Courier Enhancements: Fax, Data and High-End Features
