BRIEF DESCRIPTION
The D-MON is a passive ISDN S-interface tester that allows to monitor the EURO-ISDN (E-DSS1) D-channel protocol in both directions. It is a very small box designed for mobile use and powered by rechargable batteries or via an AC mains power adapter. It contains all hard- and software required to decode and trace the ISDN D-channel protocol. RJ45 sockets are provided for the connection to the S-bus and the ISDN terminal equipment. To upload and display the trace information the serial port of the PC has to be connected to the V.24/RS232 interface of the D-MON via a 9-pin D-sub connector. Communication via the COM port is independent of make or model of the PC. Operation of the unit is possible using any terminal emulation software. The D-MON is controlled using simple commands which do not require any ISDN protocol experience. For enhanced operation conveniences the PC software WIN-D-MON is available to use the D-MON as an application in windows (future option).
