For lower security systems a longer polling time can be used.

By default, Polling Overdue and Polling Restore for each remote IRIS dialler

are only reported by the Polling Engine acting as Main for that dialler. Some

ARC systems cannot differentiate Polling Overdue or Polling OK messages

seen on the serial links from the Main and Backup Polling Engines and this

mechanism prevents potential confusion at the ARC in situations where, for

example, there was a transient network problem and the IRIS dialler failed to

connect to Main and so polled to the Backup.

In circumstances where there has been a major failure at the site where the

Main Polling Engine is located and no polls can get through, if the ARC

wishes the Secondary Polling Engine to report Polling Overdue and Polling

OK, this can be enabled by setting the Polling Accept option for that Polling

Engine to “All Diallers”.
