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.32terbo
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
The full list of features that will be added to the Courier line
includes:
Data Rate Enhancements:
