Optical networks, network elements, and methods of use are described herein, including an optical network comprising head-end and tail-end network elements, an optical multiplex section (OMS) connecting the head-end and tail-end network elements, and one or more intermediate line amplifiers in the OMS between the head-end and tail-end network elements. The head-end network element may store first information indicative of a first tilt control section having the head-end and tail-end network elements as endpoints; determine information indicative of a change in topology of the OMS, such as that a first intermediate line amplifier has switched from a non-monitoring to a monitoring mode; and store second information indicative of a second tilt control section having the head-end network element and a new tail-end network element, such as the first intermediate line amplifier.
