INNOVATIVE
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 work-
day away from their desk. Complemented by 4 fully programmable Feature Keys, the DSX Cordless Tele-
phone 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 pro-
gramming 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 high-
density 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 auto-
matically 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 state-
of-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.
Innovative leadership and longevity are a rare combination among technology companies. Founded in 1899,
NEC has grown to a nearly $50 billion enterprise that produces 15,000 products in 126 manufacturing plants
worldwide. NEC pioneered the development of telephones and switching systems early in the 20th century,
and has maintained a leadership position in communications and networking ever since.

DSX-80/160 CPU
DSX-80/160 CPU Card
The CPU Card is the system’s control center. It provides the system’s Linux operating system, central pro-
cessing, stored program, and memory for the customer’s site-specific data. Every system requires a CPU
Card. In addition, it also provides:
• CompactFlash card interface (for IntraMail, software loading, and database backup)
• Conference circuits, DTMF receivers and DTMF generators
• Real Time Clock
• NAND Flash for storing the system database
• Battery for short term (14 day) backup of the Real Time Clock and station parameters
• Two audio inputs for Background Music and Music on Hold (1/8” mono minijacks)
• One audio output for External Paging (1/8” mono minijack)
• Ethernet and USB ports for local and remote PC Programming
• RS-232 serial port for Station Message Detail Recording
• Built-in V.32BIS 14.4K BPS modem for remote maintenance
The CPU also has a reset switch that provides the following three functions:
1. System reset (when momentarily pressed).
2. System initialization (when held down as power is turned on).
3. Software update (when held down for six seconds while software update CompactFlash card is installed).
Tips to remember:
• When connecting to the CPU audio inputs or outputs, make sure the connected device is compatible
with the CPU audio specifications. See Specifications and Parts (page 27) for more.

14 ◆Components DSX Component Guide
DSX-80/160 Station Cards
DSX-80/160 16 Port Digital Station (16ESIU) Card
Each 16ESIU Card connects 16 digital extensions (i.e., DSX keysets). The 16ESIU has a Mode Switch (for
taking the card out of service). It also has a status LED that indicates proper card operation — as well as a
port activity LED that flashes faster as traffic on the card increases. You can install up to two 16ESIU Cards
in a DSX-80. You can install up to six 16ESIU Cards in a DSX-160. See System Configuration (page 24) for
more.
Tips to remember:
• In DSX-160, you must install a separate power supply for every two 16ESIU Cards installed.
• In both DSX-80 and DSX-160, you must install a 16ESIU Card in slot 1.
• You can install additional 16ESIU Cards in any slot.
DSX-80/160 16 Port Analog Station (16SLIU) Card with HV Message Waiting
The 16SLIU Card connects 16 analog extensions which are typically used for single line telephones and fax
machines. Just like the 16ESIU Card, the 16SLIU Card has a Mode Switch (for taking the card out of ser-
vice), a status LED indicating proper card operation, and a port activity LED to indicate traffic on the
card.See System Configuration (page 24) for more.
Tips to remember:
• The 16SLIU Card provides high voltage message waiting for single line sets with high voltage mes-
sage waiting lamps.
• The 16SLIU Card also provides Caller ID to single line sets.
• You can install a 16SLIU Card in any slot except slot 1.
