// - 'dataModel' is the csv file name that contains tr069 data from a CPE. This
// name should not be prefixed with the directory path and should be only the
// file name inside the ../models/ directory without the ".csv" file extension.
// - 'serialNumber' and 'macAddr' are used to uniquely identify the CPE.
// - 'verbose' is a flag that controls legacy messages printed when a
// connection is received.
// - 'periodicInformsDisabled' is a flag to disable automatic informs.
