U.S. Robotics Introduces Symmetrical x2 Over ISDN; Extends Small Office, Desktop x2 Host Solution With New Courier I-modem Capabilities.SKOKIE, Ill.--(BUSINESS WIRE)--June 6, 1997-- Symmetrical x2(TM) Over ISDN ISDN in full Integrated Services Digital Network Digital telecommunications network that operates over standard copper telephone wires or other media. Provides Near ISDN Speeds, Can Save Users Up To 50 percent on ISDN Tolls U.S. Robotics (U.S. Robotics, Inc., Schaumburg, IL, www.usr.com) A modem manufacturer highly regarded for its quality products. The company manufactures its own chipsets (data pumps) and often leads with innovations. Its HST protocol was a high-speed, reliable protocol before V. (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :USRX) today announced it is shipping new x2 features and ISDN enhancements for the Courier(TM) I-modem with ISDN/V.Everything(TM). Now, customers who use U.S. Robotics' Courier I-modem can send and receive information at x2 speeds, taking advantage of x2's higher performance for both uploads and downloads at near ISDN speeds -- at a fraction of the cost. Other new Courier I-modem features include automatic pass-through compression, data over voice and dynamic bandwidth allocation Dynamic Bandwidth Allocation (DBA) is a technique by which traffic bandwidth in a shared telecommunications medium can be allocated on demand and fairly between different users of that bandwidth. , which further maximize performance and reduce costs. x2 Host Mode With the Courier I-modem, U.S. Robotics is the only vendor offering a low-cost, desktop 56 Kbps remote access solution. x2 is a revolutionary analog technology from U.S. Robotics that takes advantage of today's telephone network to deliver data significantly faster than standard V.34 modems. The Courier I-modem can act as a remote access host, allowing a remote user to dial in and download information through the I-modem at x2 speeds. The product supports x2 host site applications, as well as symmetrical 56/64 Kbps data transfers. The Courier I-modem can send and receive x2 calls as well as standard ISDN and analog transmissions. For small offices that require high speed connections, the Courier I-modem provides a simple, cost-effective x2 host solution allowing remote users to dial into the office network with their 28.8 analog modems, x2 modems or ISDN terminal adapters. "The Courier I-modem is all you need to capitalize on Cap´i`tal`ize on` v. t. 1. To turn (an opportunity) to one's advantage; to take advantage of (a situation); to profit from; as, to capitalize on an opponent's mistakes s>. the advantages of both analog and ISDN worlds," said Jennifer Schuster, group manager of client products at U.S. Robotics. "Because its interface to the network is digital while supporting an integrated x2 modem, the I-modem provides high speed x2 and ISDN data transfers to and from the small office or the Internet." x2 in Both Directions (Symmetric) Provides Cost Savings The Courier I-modem can achieve symmetrical x2 speeds when any x2 host product is on both ends of the connection. Because the actual connection is digital on both sides, symmetrical x2 data transmissions are possible up to 64 Kbps. By using Courier I-modems in x2 symmetric mode, it's possible for users to increase bandwidth while maintaining the cost savings of sending data over voice. For example, data over voice makes ISDN data calls appear as voice calls to the telephone company and the call is tariffed that way. I-modem users will receive reduced ISDN usage charges with the data over voice feature and may decrease connect time based charges up to 50 percent in certain areas. This symmetric mode may be used with any x2 host product. This includes another Courier I-modem, NETServer 8/16 I-modem, MP 8/16 I-modem or Total Control(TM) remote access server with PRI PRI: see Institutional Revolutionary party. (Primary Rate Interface) An ISDN service that provides 23 64 Kbps B (Bearer) channels and one 64 Kbps D (Data) channel (23B+D), which is equivalent to the 24 channels of a T1 line. . Dynamic Bandwidth Allocation Additionally, The I-modem's Dynamic Bandwidth Allocation (DBA) feature saves on toll charges by waiting until data transfers reach pre-determined threshold levels before bringing up the second B-channel. Usage charges for the second B-channel are incurred only when Multilink PPP See PPP. is initiated through DBA. With DBA, the second B-channel is brought up and brought down from the call as data transfer requirements change. Auto Pass-Through Compression for Maximum Performance Auto pass-through compression ensures the highest data throughput possible by automatically detecting common host-based data compression data compression Process of reducing the amount of data needed for storage or transmission of a given piece of information (text, graphics, video, sound, etc.), typically by use of encoding techniques. , such as Windows(R) 95 Dial-up Networking See dial-up network and Win Dial-up networking. , and sending it across the ISDN line. Because host-based compression is done before sending the data across the DTE (Data Terminating Equipment) A communications device that is the source or destination of signals on a network. It is typically a terminal or computer. Contrast with DCE.  DTE - Data Terminal Equipment port, data throughput rates up to 512 Kbps are possible, eliminating the serial port bottleneck and improving overall performance. Additional Features: Universal Connect, Turbo PPP (Point-to-Point Protocol) The most popular method for transporting IP packets over a serial link between the user and the ISP. Developed in 1994 by the IETF and superseding the SLIP protocol, PPP establishes the session between the user's computer and the ISP using , Dynamic Voice Override The Courier I-modem also includes: -- Universal Connect, which automatically negotiates calls as ISDN or analog and connects at the highest possible speed supported by the device on the other end of the connection. -- Turbo PPP(TM), a feature set designed by U.S. Robotics, which includes Multilink PPP, multiple forms of software based compression (Microsoft(R), Stac(R), Ascend(R)), and the ability to use Multilink PPP in applications where only PPP is supported. -- Dynamic voice override supports voice communications over a standard analog phone The original telephone technology, which converts air vibrations into an analogous electrical frequency. Unless a key telephone system, digital PBX or voice over IP (VoIP) is used, most homes and small offices still use analog phones, and the local loop is mostly analog. , dropping one of its two 64 Kbps channels to send a voice call and automatically bringing the channel back up for data when the call is complete. This allows data to be sent without interruption. The Courier I-modem is available in an external or internal version, list price between $339 - $399.
