Active Bundle Time Active bundle time is the period of time that the system tries to activate an
established but inactive bundle. A bundle is necessary between local and
remote devices to transmit TDMoE traffic. If the local device receives the
MAC address of the remote device through ARP Response (Address
Resolution Protocol), then the traffic can be steadily forwarded, and Active
Bundle Time will not be triggered. However, if the local device cannot
receive TDMoE traffic from the remote device, this situation is the so-called
“Remote Loss”. Hence, the local device will send ARP request frames and
request the MAC address of the remote device. Once a bundle is inactive,
this status would trigger its own Active Bundle Time in operation.
Alarm Filter When an alarm occurs, the system will monitor the alarm status. If the
alarm still exists after the configured time, the alarm queue will be issued.
