DSX Series


The DSX-40 represents the next generation of DS Series platforms, and is designed for residential and small commercial applications. The system shares station equipment, IntraMail voice mail, and programming design with the DSX-80/160.

The standard DSX-40 configuration provides 4 CO/line ports, 8 digital station ports, 2 analog station ports, and 2 analog doorbox ports with relay controls. The system is easy to install and expands easily to 8 lines with 24 business phones or 18 single-line phones, or a mixture of both, via expansion cards.

Notable system features include:

  • Built-in 2-port automated attendant, with multiple line greetings, and customizable dial action tables.
  • Built-in caller ID information that can be logged at each extension and that can be sent to analog phones with caller ID capabilities.
  • Workgroup features such as Call Coverage, Extension Hunting, Group Call Pick-up and Multi-Party Conference
  • Intuitive system programming via DSX telephone or the System Administrator software, which is available for free download, from the DSX support website (link to www.necdsx.com)
  • Optional DSX IntraMail voice mail/ automated attendant that provides more advanced automated attendant features than provided by the built-in auto attendant. Available in either a 4-port x 8-hour, or 8-port x 16-hour configuration.


NEC designed the DSX hybrid key system from the ground up with affordability in mind. High-density circuitry maximizes economy per port. Native support for T1 and ISDN PRI provides maximum connectivity for a low initial investment. The DSX system offers high performance, flexibility and the ability to custom design a system that meets your company's specific telecommunication requirements.

Innovation starts with the new ergonomically styled DSX telephones. All models feature the same thin, floating design, two-position angle adjustment for effortless viewing of the large LCD display, and built-in wall mounting. Advanced features and intuitive soft keys provide users with one-button access to extensions, lines and system features. With many models to choose from, each user can enjoy customized service and performance.

The DSX features a family of telephones that sets the new standard in office communications.

    All models include:

  • 10 One-Touch Speed Dial Keys
  • Dual Color Red/Green LEDs
  • Built-in Speakerphone
  • Built-in headset jack
  • Enhanced models include a back-lit LCD display and illuminated keypad

Innovations continue with the DSX system. Right out of the box, the DSX has built-in Automated Attendant which answers incoming calls, plays a greeting, and allows callers to directly dial extensions and departments without operator assistance or additional equipment.

Over a decade of rigorous 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, the DSX will be your reliable business partner for years to come.
