DSX from NEC takes the lead with state-of-the-art innovations sure to make your business communications
more efficient, profitable, and enjoyable.
Innovation starts with the new sleek DSX telephones. All models feature the same thin, floating design, two
position angle adjustment for effortless viewing, and built in wall mounting. The 22-Button Display offers a
large 3-line-by-24 character display, four interactive soft keys, and a built in speakerphone. The 34-Button
Display is enhanced with a backlit display and illuminated dial pad (for improved low light viewing), as well
as additional feature keys. An advanced model of the 34-Button Display provides a built-in half-duplex
speakerphone. The 34-Button Super Display has all the features of the advanced 34-Button Display and
additionally offers the user a 9-line-by-24-character display and 12 interactive soft keys. Rounding out the
line, the DSX Cordless Telephone provides mobility and flexibility for those who spend much of the workday away from their desk. Complemented by 4 fully programmable Feature Keys, the DSX Cordless Telephone achieves a whole new level of convenience and mobility.
Innovations don’t stop with the DSX telephones. Right out of the box the system has a two-port Automated
Attendant with no optional equipment required. The capability for full-featured IntraMail Voice Mail with
Automated Attendant is inherent in the system and only requires an IntraMail flash card to activate. Program
on-site from the telephone or from a PC connected to the system’s ethernet or USB port. PC remote programming is available through the ethernet port or built-in modem.
AFFORDABLE
NEC designed DSX from the ground up with affordability in mind. Economy per port is maximized by highdensity circuitry. All DSX telephones have a speakerphone and display for increased functionality and total
lower station cost. Native support for ISDN PRI and T1 provides maximum connectivity for low initial
investment. Since DSX is simple to install and easy to use, the expenses of configuration, programming, and
post-installation training are minimized.
The cost-effective IntraMail provides sophisticated Voice Mail and Automated Attendant features previously
available only with expensive add-ons or costly external units. It is available in two configurations: 4 port/8
hour and 8 port/16 hour. The IntraMail Automated Attendant includes the call answering features you
demand such as dial access to extensions, unique day, night, and holiday answering (Flexible Answering
Schedules), the ability for two companies to share the same IntraMail (Multiple Company Greetings), and
the capability to dial employees by entering their names instead of extension numbers (Directory Dialing).
IntraMail Voice Mail is much more than simple messaging. Advanced IntraMail features allow you to automatically place a return call to the message sender (Caller ID with Return Call), screen your incoming calls
(Call Screening), forward a message to a co-worker (Message Forward), and send a call to a co-worker’s
mailbox (Transfer to a Mailbox).
DSX is sized right, starting with the economical 40-port DSX-40, growing into the 80-port DSX-80, and
culminating in the 160-port DSX-160. To maintain the value of your investment, all the components of a
DSX-80 can be used in DSX-160 just by adding a DSX-160 cabinet. Even when growing from the DSX-40,
your investment in programming, telephones and other station equipment is retained.
RELIABLE
Over a decade of intense feature development ensures that the core DSX call processing features are mature,
efficient, and reliable – yet intuitive and easy to use. Combined with end-to-end Quality Assurance and stateof-the-art circuit design (which achieves new standards for efficiency and economy), you are assured that
DSX will be your reliable business partner for years to come.
