Number of undelivered packets to determine connection failure — a

counter of undelivered packets (8 packets by default).

The time before raising the alarm by the communication loss between hub

and device is calculated with the following formula:

between the hub and the connected devices; however, a short ping interval

interval.

Note that the interval limits the maximum number of connected devices:
