Rockwell Modem

It has been predicted that the arrival of the all-digital telephone network would soon make modems obsolete. Yet this has not happened, nor is it likely to for at least another ten years. Meanwhile, the ever-increasing demand for data-communications systems, of which analog-based modems are a large and essential part, continues to elicit new theories and exciting applications. This book examines these new theories and applications of modem design, and includes several practical examples of how to choose and design all the major components of a modem. Emphasizing an applied approach throughout, The Theory and Practice of Modem Design first describes the various media through which data must be transmitted— especially the most important one, the telephone network. Then, after a review of the basic theories of data transmission, the book discusses modulation methods, including the analysis of two new, controversial methods, with a fresh assessment of their usefulness and a description of how they can be implemented. Next, the book describes the overall architecture and all the major components of a receiver (with separate chapters for the critical functions of timing and carrier recovery, and linear and nonlinear adaptive equalization) using a careful blending of theory and specific practical examples, and considering both hardware and software implementations. The Theory and Practice of Modem Design also discusses two topics of great current interest to modem designers: convolutional coding for error correction and full-duplex operation (using both frequency division multiplexing and adaptive echo cancellation). There is also a section that explains all the ancillary functions that apractical modem must perform, plus two appendices that describe computer programs and diagnostic tests that can be used for designing and debugging.

Modem on Hold makes the most of optional Call Waiting, Caller ID, and Voice Mail services available from your phone company Quick Connect reduces the time it takes to make a connection to your service provider By remembering the line conditions from the previous connection, the modem can bypass portions of its training sequence and get you online faster V.PCM Upstream allows the modem's upstream communication to reach speeds up to 48 Kbps Choose whether to maintain the fastest possible downstream speed (up to 53K) or whether to balance your connection for somewhat slower downstream and faster upstream communication 56 Kbps data/14.4 Kbps fax Enjoy high-speed downloads with the V.90 56K standard Universal compatibility with V.90, x2 and V.34 technology Advanced line probing technology delivers higher modem throughput and more reliable connections Controller-based for superior performance Powerful communication processing functions are built into the modem itself so there's no need to tie up your PC's resources Designed for the RS-232 serial port found on virtually all PCs Internet phone-ready Includes RJ-11 phone cord, AC power adapter, software and manual.

K56flex - K56flex (a combination of Rockwell's K56Plus and Lucent's V.Flex2 proposals) was a modem chipset from Rockwell and Lucent that gave users the possibility of receiving data on ordinary phone lines at 56 kbit/s as opposed to the previous maximum of 33.

ADSL modem - An ADSL modem, also known as a DSL modem, is a device used to connect one or more computers to a phone line, in order to use an ADSL service. To the end-user, it is functionally very similar to an analogue modem, however the underlying technology is substantially different.

Apple USB Modem - The Apple USB modem was introduced after the 56k modem was dropped on the iMac G5 (October 12 2005 Revision.) A device driver for the modem was introduced with MacOS X version 10.

Modem Sharing Device - A Modem Sharing Device (MSD), also commonly known as a Line Sharing Device (LSD), modem sharer, or line sharer, allows multiple devices to share a serial connection. Only multipoint serial protocols such as bisync are supported.
