The middle level of the control hierarchy is the Line Controller (LNCTL) circuit
pack. The LNCTL circuit pack is responsible for fault recovery. The LNCTL circuit
pack communicates with the board controllers to activate protection switching.
The middle level of the control hierarchy is not needed in the FT-2000 OC-48
Repeater Bay. Therefore, the FT-2000 OC-48 Repeater Bay does not require any
LNCTL circuit packs.
The system controller complex is the highest level of the control hierarchy. The
system controller complex consists of the System Controller (SYSCTL) circuit
pack and the System Memory (SYSMEM) circuit pack. The system controller
complex performs the non-real time intensive functions requiring overall system
knowledge. The system controller complex also plays a major role in providing
the extensive operations, administration, maintenance, and provisioning
