Loop Detect Enables detection of loops in the TDM
network. When a loop is detected, a
corresponding alarm is recorded in the alarm
log, and all Ethernet frames being looped
back from the TDM uplink are blocked, and
prevented from being sent back to the
user's LAN. This mechanism prevents the
occurrence of undesired broadcast storms
and IP loops in the user’s LAN due to a loop
on the TDM network.
