the eye of your ISDN line for
the Basic Rate Interface (BRI)*)


eyeSDN

  • helps you save on phone costs;
  • tells - in Normal Mode - whether the Customer Premises Installation (CPI) is doing something;
  • supports the installation work;
  • helps with error detection.

eyeSDN

  • detects data theft;
  • reports every activity on the S/T bus;
  • is independent of the data protocol;
  • does not use any more energy than a Terminal Equipment 1 (TE1);
  • hardly uses any energy in Restricted Mode.


Function:

eyeSDN serves as a detector of activities on the S/T bus of a Basic Rate Interface (BRI)*). As soon as a data transfer is taking place (or even a sufficiently large spurious signal is present), the indicator lights up. E. g. a fax is coming or ...

Examples of suspect activities:
  • A receiver is not correctly replaced.
 
  • Your computer is inadvertently still on-line.
  • Your children/cats play with the telephone.
  • Your computer establishes unnoticed connections and/or doesn't quit them.
  • The neighbour telephones with a cordless phone at your expense.
  • A hacker forces an entry through the service access.
  • Somebody is listening in from another telephone.
  • Someone is tapping the S/T bus.


Installation:

Be certain that the power supply plug of your NT1 is plugged into the mains outlet, or the S/T bus is otherwise supplied sufficiently with energy for the Normal Mode.

Connect eyeSDN to the S/T-Interface jack, e. g. to an S/T-Interface jack in the NT1 of the Post Office

 
- or -
connect your Terminal Equipment 1 (TE1, e. g. your telephone) and eyeSDN by a duplex jack to the S/T-Interface jack.

eyeSDN does not use more energy than a Restricted Mode compliant Terminal Equipment 1 (TE1), therefore you can attach several eyeSDN at different workstations, where you usually stay.






If the procedure "AlwaysOn/DynamicISDN (AO/DI)" - e. g. T-ISDN @ctive or Notifyer - might be active in your system, then the indicator lights up continuously.

In order to enable the selective ability of eyeSDN, AO/DI must not be active.

Also, without AO/DI, there are sorts of Terminal Equipment 1 (TE1) or Private Branch Exchanges (PBX), which do not leave the S/T bus in peace during inactive phases, so the display lights up continuously (see also inside the FAQ list).

Therefore, buy equipment only with right of return (as for instance with CONRAD), until its compatibility is verified.

*) On ordering your ISDN access you have selected the type of interface. If you have rented continuous monitoring, or an Extended Rate Interface instead of a Basic Rate Interface, then

- because of the continuous monitoring - the data traffic with the switching center of the telephone service provider stops only in case of fault. Then, eyeSDN is a mere Normal Mode indicator:

It does not distinguish between connection breaks and (perhaps suspicious) connections, but between Normal Mode and Restricted Mode.
