Link Lock Security Feature
The purpose of Link Lock
Link Lock is a part of the WinLink security concept intended to meet a
form of abuse encountered in the field. It is designed to prevent the
situation where a remote ODU can be stolen and used as a “pirate” link
to steal services or information. The Link Lock feature actually locks
the local ODU to be synchronized ONLY to specific remote ODU. It is a
site oriented feature.
The lock can only be set from a live link. It is based on MAC
authentication and is site oriented and activated on a per ODU basis.
For example, if you lock the remote ODU to the local ODU, you must
still lock the local ODU to the remote ODU to ensure complete two way
locking.
It can only be removed when the link is unsynchronized. In such a
case, an alarm is raised by the WinLink™ 1000 Manager.
