K1103 Siemens Protocol Tester

The Protocol Tester K1103 consists of a PC card with 8 MB RAM, a 540 MB hard disk and a 1.44 MB floppy disk. A TFT color display, which can be read without impairment even under bad lighting conditions, is used as the display. Graphics control is by means of a VGA card. The keyboard can, if necessary, be removed from the tester in order to enable more comfortable working. MS-DOS 6.2 is used as the operating system. Line activities are displayed on LEDs on the front of the instrument.

The test modules can be inserted in the Protocol Tester K1103 simply by plugging them in. No further hardware settings or reconfiguration is required as this is executed at a keystroke by the testing software provided. When the K1103 is connected to the PCM links, the autoconfiguration function determines the signaling channel search and the framing search. No preliminary manual settings are required. As soon as the autoconfiguration is completed, all the active signaling channels are available and can be displayed simultaneously or separately on the screen. Again a keystroke is all that is needed to select a particular link and thus reduce the screen display to the required data.

The Protocol Tester K1103 also has a wide and impressive range of powerful display formats. Message components from any source are decoded on-line and to the maximum possible depth if required. All the important message parts are output not only in binary or hexadecimal but also in mnemonic form (on-line and off-line in parallel). Special search functions permit selective tracing of any desired message parts, e.g., an IMSI/TMSI (International/Temporary Mobile Subscriber Identification).
