Digital vs. Analog office phone systems

Most newer and more expensive phone systems communicate via digital technology. This means that sound is transmitted as bits of data rather than audio waves.

Theoretically, digital transmission has many advantages over analog transmission. Digital signals are less affected by interference and line degradation, meaning that digital lines have virtually no static or hiss.

However, most businesses make outgoing calls over regular analog lines. This means that even a digital phone system must convert signals back to analog waves whenever a call leaves the office. Because very little sound degradation occurs within the smaller confines of an office, analog systems actually sound about the same as their digital counterparts. The main reason for buying a digital system is that these systems tend to be better equipped to connect with accessories such as voice mail or caller ID.

Introduction to NEC Phone Systems

NEC takes the lead with state-of-the-art innovations sure to make your business communications more efficient, profitable, and enjoyable. Superior ergonomic styling offers a slim, sleek, compact design with a quality feel that is an attractive addition to any work environment. All models feature the same thin, floating design, have a built-in speakerphone, two-position angle adjustment for effortless viewing of the large LCD display, and built-in wall mounting. Enhanced models also offer a backlit display and illuminated dial pad. Innovations don’t stop with the DSX telephones.

Right out of the box, the system has a built-in Automated Attendant which can answer incoming calls, play a greeting, and allow callers to dial extensions and departments directly without operator assistance or additional equipment. DSX is sized right – starting with the economical DSX-40, progressing to the DSX-80, and reaching maximum system capacity with the DSX-160. To maintain the value of your investment, all the circuitry of a SX-80 can be migrated to the DSX-160. Even when growing from the DSX-40, your investment in programming, telephones, and other station equipment is retained.
