BRI and PRI Simulator emutel Ultra Overview

emutel Ultra is a standalone or rackmount unit that comes in five variants giving 8 BRI, 2 PRI and 8 BRI, 2 PRI and 15 BRI, 8 BRI and 14 analogue or 2 PRI, 8BRI and 14 analogue. emutel Ultra can emulate different country specific networks by adding network personality cards & networks supported include North American, NTT, Euro-ISDN, VN3, ITR6 and BTNR191. Protocol analysis option is also available on emutel Ultra.

Emutel range of ISDN network simulators will solve the problem. Emutel is a family of products which simulate the operation of a carrier network for PRI, BRI and PSTN.

  • Ideal for product development, testing and demonstrations
  • Make free BRI-BRI, BRI-PRI, PSTN-PRI, PSTN-BRI calls
  • Take your ISDN with you wherever you go
  • Test and develop products for another country's network
  • Simple configuration/management using Windows app
  • Extensive support for supplementary services
  • Leased line operation for testing permanent connection equipment
  • X.25 for testing and demonstrating packet switching equipment
  • Power feeding supported on BRI interfaces
  • Universal power supply allows you to use Emutel in any country

emutel™ Ultra Features

By simulating the operation of a Central Office Switch, emutel Ultra provides both Basic Rate ISDN (either U [2-wire] or S [4-wire] connection), Primary Rate ISDN (E1 or T1) and up to 14 Analogue Telephone connections which may be used just like regular ISDN lines or employed to carry out equipment testing. (see unit options for more details & link to unit options).

Almost every feature of emutel Ultra can be customised, for example, the entire directory numbering structure can be changed. Special numbers activate network conditions such as User Busy or Call Rejected. Line power can be switched on or off.

emutel Ultra is also extremely easy to use with indicator LEDs showing at a glance what each terminal is doing and a windows application program displaying Protocol Analyser information and allowing simple device configuration.

emutel Ultra is a truly international product. By plugging in personality cards the system can accurately emulate ISDN variants in a whole range of different countries. Cards are available for BTNR 191 (UK), VN3 (France), ETSI (Europe), ITR6 (Germany), NTT (Japan) and AT&T 5ESS, National-ISDN & Nortel DMS100 (North America). Network dependent supplementary services are also supported.

At just 3.4 Kg, emutel Ultra is easily portable and since terminals can be powered directly from the interfaces it really is the ideal system for use at demonstrations, presentations, exhibitions and in production line testing. In addition emutel Ultra's universal power supply, which automatically switches between 240V and 110V, ensures that the system is transferable between the US and Europe without any adaptations.

  • A wide range of interface types allow you to simulate all of the functionality of regular ISDN lines - and much more
  • Configuration is extensive but simple using a windows application or ANSI based terminal
  • Helpful LEDs show the status of each interface at a glance
  • emutel Ultra can emulate different variants of ISDN by changing the PCMCIA personality card at the front
  • Depending on network type a range of supplementary services are supported for telephones and PBXs
  • emutel Ultra's weight, size and universal power supply make it a convenient portable network for exhibitions and on site customer demonstrations
