The meter will be able to 'Push' register readings back to the utilities
information system at regular predefined intervals. The reading interval will
be configurable by the system.
The data returned to the system will hold both credit and prepayment
information for the meter. A scheduled read will be a single SMS message
in length. The returned message format will be as follows:

The meter-reading schedule may be configured around the following one of
the following routines:
Daily Read

Weekly Read

Monthly Read

 Billing Period Read.
In order to randomise the reading time and prevent all meters sending their
data back to the CS at the same time, the meter will take a snapshot
reading at the end of a random offset. The offset period shall be a
maximum of 2 hours beginning from midnight; the meter will select a
random offset within this period, the meter-reading schedule will therefore
be as follows:
 Daily Read – A snapshot of registers taken between 00:00 and
02:00 and transferred to the system.
 Weekly Read – A snapshot of registers taken between 00:00 and
02:00 Monday morning each week and transferred to the system.
