3. REMOTE CONTROL
Depending on the device type there are many possible remote control capabilities.
Outputs can be controlled from any telephone, both landline and mobile, the number of which
was previously stored into the SIM card phonebook or the internal device phonebook: these are
authorized users.
In order to be recognized the user must verify that the presentation of his telephone number
(CLIP) is enabled. The unit will not answer to unrecognized calls.
3.1 Call control (CLIP)
Any incoming call from authorized users can activate outputs.
Depending on system settings [§ 13.1] different action can take place.
3.1.1 TOGGLE
Incoming voice (or fax) calls will toggle regulation control on to off or vice-versa, data calls will
do the same on output 2. A ringback will be issued only when an output is turned on.
If the user waits online, after the time specified in
answ
, Gsm will answer, playing a
low tone after output release or four high tones after output activation. No ringback will be
issued in such case.
