Configuration Notes:
You need a constant data stream to transfer the configuration. The stream must also reach a certain speed, which is checked before the transfer is made.
If the criteria are not met, no connection is set up to the panel. Furthermore, the connection must be very stable. Especially over long segments, e.g. international connections, the connection is often not very stable.

Note:
It is generally recommended not to do project downloads via TeleService using GSM communications.

Technical background:
The transfer route, e.g. abroad, is set up via roaming. This means that the connection runs over multiple servers. The protocols sent are delayed accordingly depending on the number of servers involved. If a protocol is not acknowledged within the timeout period, no connection can be set up to the panel.

In contrast, with STEP 7 you get a message if the connection is to be interrupted during transfer. Once the connection has been set up again the transfer can be continued from the point where it was interrupted.
