4.7.1 Servicing
If a PC is available at the installation site, a USB link is established between the
coM.sat ISDN Basic UMTS and the PC and after calling up the coMsat.exe
application, the link to the TA can be established by logging in for making authorised
changes to the configuration. The next steps are then reading the configuration or
updating the firmware.
4.7.2 Remote servicing
The other possibility is to set up a link between the service PC and the TA via a
GSM/UMTS network. To do this, a coM.sat ISDN Basic UMTS, a coM.sat ISDN Plus
or a GSM/UMTS modem must be connected to the service PC itself. Furthermore,
the numbers of the TAs to be serviced must also be known at this site. The link is
now made as follows:
The service PC sends the coM.sat ISDN Basic UMTS a short message (SMS)
containing the callback number. The device then sets up a data link.
After the SMS has been sent, the service PC is switched over to the terminal window
and the channel via which the message was transmitted was switched to transparent
mode. When the return call is received, a “RING“ can be identified in the terminal
window. The “RING“ is now manually answered with the ”ATA” command. The link to
the remote device is now displayed by the “CONNECT“ message. After setting up the
link, the service PC can be used to work with the remote device, as if it were
connected directly to the PC. For example, the configuration data can be
interrogated, altered and sent back. In this process, a SIM card that permits the
transfer of data must be inserted in the device used in the service centre. The phone
numbers and, if necessary, the passwords of the remote device must be known.
