Tired of watching time tick away as you modem a file to your service bureau? jealous of the dedicated high-speed transmission networks that only weekly magazines like Time and Newsweek can afford? A system being tested at McGraw-Hill Inc. is vying to offer similar performance at lower cost to smaller magazines.

The test, sponsored by New York Telephone, uses a service called Switched 56-data-only telephone lines that transmit information at 56,000 bits per second, six times that of the fastest modems. But unlike a dedicated point-to-point line, which connects a magazine to one location only, Switched 56 lines can be used to dial up any location that also has the service-potentially at a lower monthly cost than a dedicated line, depending on usage.

Faster transmission and the resulting ability to send larger files could let magazines extend deadlines; save on messengers, overnight fees and phone charges; and even allow transmission of pages with images in place, says Cesare Del Vaglio, director of advanced desktop publishing and interactive media applications, Corporate Information Management, at McGraw-Hill. Ultimately, it will make in-house imaging and color work more feasible, he says.

McGraw-Hill's open-ended test started in March. The current system, created by Basking Ridge, New Jersey-based Cornell Data Systems, includes QuickMail electronic mail and proprietary software that automatically dials up remote locations.

Switched 56 transmissions are more accurate than those over ordinary phone lines, says Cornell Data Systems president Craig Shrader, because data-only lines are less noisy and therefore more free of errors. …
