once And then NLLW hang up. Further round might be activated only by new
change on input INPUT. The voltage must returns back to stand by mode. The
change on input INPUT must happen again. During failure calling are all other
features available.

2.2.4 Service calling ( from timer)
Service calling is optional parameter
. You alsé define if this parameter is
activated since first connection of NLLW to telephone line.This service calling is
adjustable from 1 to 9 day period, for example 3 means that NLLW is make
automatically every 3th day a call to preprogrammed number. (test of NLLW
functionality).
For service calling you programm special number which might be of
course the same as emergency or failure calling number. You can also select if
will be dialling only this number or all round of emergeny numbers ( then you
have max 7 numbers) .
The service calling is repeated in period 0-9 min ( programmable) until
succesfull call ( confirmation). The repeated time between calls is
programmable because to service department can call more NLLW. To avoid
of problem that service department line is busy you can programm different

2.2.5 End of calling
– call confirmation
The NLLW enables to programm at every number if will be confirm or
not. Every call needs authorisation if it was succesfull or not. Therefore analog
line doesnt support any kind of authorisation (signalling) we can define success
of call by 2 ways. The NLLW needs this info to not dial further numbers.
First way (
no confirmation
) is detection that call was succesfull on the
base control ringing tone (CRT). It is tone which we are hearing in handset
when make call to other subscriber. Thed NLLW detects this tone And when is
missing for certain time then evaluate the call was succesfull (Green indicator
light up and yellow light down). The time which define undetection of CRT (
called part picks up) is adjustable because each type of PBX can be different.
Usually should be 5 seconds as the best. At this call authorisation stays
possibility confirm the call by dial confirmation characters (*xxxxxx, where
