Modem parameters
If modems are used for remote control, it is necessary to program certain parameters in the ATL needed to
control the modem connected to the ATL itself. Due to their particular structure, these parameters are not
available on the keyboard-display of the device, and may therefore only be set through a PC and remote
control software.
As it is necessary to program these parameters
before
being able to use the modem, this programming is
usually carried out connecting the PC and the ATL directly with the RS-232 serial cable.
When a modem is used it is possible to configure the ATL so that it answers only calls from the PC or so that
it can autonomously call the PC in the case of particular events (call against alarms or at fixed intervals).
It is also possible to connect the ATL to a GSM modem, i.e. to a device that combines a conventional
modem and a cell phone, to be able to make calls also from stations with no telephone line. In this case it will
also be possible to make the ATL send SMS messages or send electronic mail messages, still as a result of
an alarm or when a fixed interval of time has elapsed (note that sending E-mails through an SMS is a service
supplied only by some phone companies).
