In-Depth Technical Features
Central Office Switch Simulation By simulating the operation of a Central Office Switch, Emutel | Symphony can provide a combination of Primary Rate ISDN, Basic Rate ISDN and/or Analog telephone connections which may be used just like regular ISDN lines or employed to carry out equipment testing. Emutel | Symphony is a modular 3 slot system comprising a system controller and up to 2 selectable plug-in expansion cards so you can build the network simulator to fit your needs (see unit options for more details).
Emutel | Symphony can be managed/configured locally or remotely with an option of an internal modem for dial up management. Attach to the LAN and configuration and analysis can be done from a remote PC in the network. This allows you to operate Emutel | Symphony in another building but configure and monitor the unit from another location. Optional protocol analysis is also available on Emutel | Symphony.
Almost every feature of Emutel | Symphony 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 and line power can be switched on or off. Emutel | Symphony 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 extensive device configuration.
At just 5 Kg Emutel | Symphony is easily portable and, since terminals can be powered directly from the interfaces, it really is the ideal system for use at demonstrations, presentations and exhibitions.
Protocol Analyser
The optional Protocol Analyser enables Layer 1, 2, and 3 to be analysed for both ISDN and X.25: Configuration for all networks irrespective of networks simulated. Support - Supplementry Services Emutel | Symphony supports the following supplementary services:
