Network Physical Interface Options (2 of 3)
Network Initiated LLB
Possible Settings: Enable, Disable
Default Setting: Enable
Allows the initiation and termination of the line loopback (LLB) to be controlled by the
receipt of LLB-Actuate and LLB-Release commands from the network.
Enable – LLB is controlled by LLB-Actuate and LLB-Release commands. Receiving a
LLB-Actuate command causes the DSU/CSU to enter a line loopback (provided an LLB
can be performed in the DSU/CSU's current state). Receiving an LLB-Release command
terminates the LLB.
Disable – The DSU/CSU ignores the LLB-Actuate and LLB-Release commands.

terminates the PLB.
Disable – The DSU/CSU ignores the PLB-Actuate and PLB-Release commands.
