5.2.2 Link Loss Forwarding

When Link Loss Forwarding (LLF) is enabled, a fault on one side of the 9145E propagates to the

other side to notify that device and stops signal transmission (see Figure 5-2). Set the LLF prop-

agation to User to Network, Network to User, or both directions. Set this in the User Interface at

the Functional Configuration screen (reference 6913303, 9145E NID Software Users Manual).
