Counter overflow
The counter value indication for costs and call-
metering pulses is continuously supervised. If the limit
is reached or if an overflow occurs, the user receives
an alarm.
The flashing alarm key indicates the alarm. Press the
alarm key to display the reason for the alarm.
Reaching the cost counter's limit
no. States the number of the alarm.
xxxx-xxxx States date and time. Format:
Date-time, MMDD hhmm.
Acknowledge the alarm by pressing menu key F4
"ACK“.
In case of an alarm we recommend to read out or print
all cost counters, and then to cancel them.
For more information see chapter CAPACITY.
Continuous updating of cost counters
ASB 150 02 guarantees that the information about
longer – and thus more expensive – calls is not lost
even in case of an unexpected power failure.
The accumulated call information is retrieved every 12
minutes by the cost counter. The cost counters keep
up the stored information even during a power failure.
CAPACITY
Conversion factor
By means of a conversion factor call-metering pulses
are converted into costs. A floating decimal point is
used for the conversion factor.
The conversion factor consists of 1–4 characters,
whereby also the floating decimal point is counted as a
character.
Thus the range of the conversion factor is between
.001 and 9999. The unit is costs/call-metering pulse.
Conversation time
The conversation time of a call is determined up to 18
hours 12 minutes and 15 seconds (65,535 seconds).
(In case of longer calls the indication remains at this
maximum value.)
Call-metering pulses
Current call
Up to 65,535 call-metering pulses are counted during
a call.
Total memory
The total memory for call-metering pulses counts up to
2
24
(= 16,777,216) pulses. In case of an overflow the
counter continues with 0.
Cost counter
Capacity and accuracy
Cost counters are presented including floating decimal
points. The counter's capacity amounts to 2
127
(= 1.7 10
38
). The counters for current cost display, last
call charges and accumulated costs to callers and
trunks contain 9 digits with 0–4 decimals.
