One example of our efforts is the new family of Intraplex ISDN products profiled in this issue. Products such as IntraLink offer a modular, flexible alternative for managing up to six ISDN circuits. Whether delivering high-quality audio for the radio industry, or providing virtual studio intercom support for television coverage of events such as the national elections, Intraplex has become synonymous with quality, reliability and robustness. Listening to customers, and sharing feedback, applications and product information will be essential to our success as Intraplex becomes a 2lst-century teenager.

Any transmission system is vulnerable to impairments in signal quality over distance.
On an analog system, almost any noise that enters the signal chain is there to stay. One great advantage of digital systems is that they are unaffected by noise below a certain threshold. High-level noise spikes, however, must still be addressed. On an analog system, a transient noise spike on the line will appear as a click or pop in the audio signal. The effect of a bit error when the audio signal is decoded can be a very unpleasant chirp.
