How is the phone line used for activity data transfer?
Periodically throughout the day the system will use the phone line to transfer your non-emergency related activity data. If the phone line is in use when the system wants to send activity data, the data transfer will not happen until the phone line is available and the system reattempts the data transfer. Conversely, if a data transfer is in progress and someone in the home picks up the phone to make a call, they will not hear a dial tone but will instead hear modem sounds that indicate that data is transferring and they cannot make a phone call at that time. The data transfer will take approximately 2 minutes and the phone will be available immediately after the data transfer is finished.
