These two phone numbers are entered in the "SMS" file card within the coMsat.exe
application. To do this, it is necessary to log in with full access rights. The phone
numbers are then entered in the "Call Number" and "Callback Number" boxes. The
"Call Number" gives the GSM phone number of the station to be called and serviced.
The "Callback Number" is the number of one of the SIM card in the channel of the
service station that transmits the SMS. Furthermore, the "SMS Service Number"
must be entered for the channel on the service station side in the "Channel 1(2) "
tab.
By selecting the "Request Callback" button, the remote servicing process is initiated.
In the first step, an SMS is sent to the device to be serviced. This then sets up a data
link to the service centre.

The device called answers after a short time with
CONNECT.
The link to the device to be serviced has now been established. The link is identified
by the relevant information being displayed on the status bar. It is then possible to log
in into the remote device to be serviced via the currently running coMsat.exe
application. All other operations on this device are carried out as already described.
It is important that the link is set up from the remote device to avoid installing SIM
cards capable of incoming data calls have to be installed in the remote device only
for update and service purposes.
If the link is to be disconnected, the string

is entered at the PC. The "+++" calls up the command mode of the device again and
"ath" ends the link.
If an update of the firmware is made a reset is carried out on the device called after
receiving and accepting the data, to be able to carry on working with the new data
afterwards.
Note: If the SMS is sent manually, a MODEM attached to the fixed telephone network
or a GSM MODEM can also be used for remote servicing.
