Telephony Training System (8086)

  • The Reconfigurable Training Module can be configured as a digital CO of the public switched telephone network (PSTN) or a digital PABX.
  • A DSP executes downloaded programs and reads or produces external signals that are used to operate real-world devices (telephone sets, phone lines, etc.)
  • Flexibility of software simulation plus realism of hardware operation.
  • Real-time, real-signal operation.
  • Provides real-life operation that is much more motivating that simple simulation.
  • Flexibility is enhanced by eliminating front panel controls and diagrams. These are all moved to a personal computer's screen.
  • System can be configured for different international standards (e.g. telephone ringing cadence can be adjusted to each country's requirements).
  • "Reconfigurability" prevents obsolescence of the system. As new standards and systems emerge, they need only be programmed and then downloaded into the training module.
  • Simple interface cards designed to be installed into the training module allow connection of real analog and digital telephone sets and trunk lines.
  • Test points are available on the front panel of each interface card.
  • Analog telephone sets come with speakerphone, LCD display, tone/pulse switch, caller identification function, ringer on/off switch, multiple phone number memory, and one-touch call buttons.
  • Digital telephone sets come with basic ISDN functions, programmable call appearance/function buttons, tiltable LCD display, and semi-duplex speakerphone.
  • When configured as a digital PABX or when a digital trunk is set up, the system allows study of the physical and network layers (layers 1 and 3 respectively) of ISDN.
