2. Automatic Redialling of Multiple Numbers without
Confirmation (GSM/UMTS/VoIP Only)
This mode is useful where no trained personnel for automatic dialling with confirmation
are available. The called party does not have to press any button. The two modes
share a set of numbers and count of cycles, respond identically to the busy tone, etc.
The only difference is that the confirmation-less mode detects the ringing tone and
recognises that the called party is off-hook (i.e. answers the call) when the ringing
tone terminates before the timeout end.

3 and 4. CPC (Antenna and KONE)
Used wherever the counterparty is equipped with the required SW. When the line is
answered, a DTMF string is sent and the lift is identified. The call is either switched to
voice communication (alarm call) or confirmed automatically and terminated (check
call), as the case may be.
Note
The PSTN connection quality is not so high as to identify the above
mentioned situations reliably in all cases. Moreover, excessive noise in the
lift cabin may decelerate automatic dialling (due to inability to recognise
the busy tone, e.g.). In general, DTMF is the most reliable type of
signalling and so is used for confirmation. Thus, the connection is
established (yet for a shorter time than usual) even in extreme cases, e.g.
when
cannot identify the DTMF.

Warning
Make sure in this mode that no VoiceMail box, FAX or any other
equipment are assigned to the numbers to be dialled that might answer
the call before the pre-programmed timeout end and thus terminate
automatic dialling.
