Depending if a slot is configured as a RX or TX slot, the structure changes in some parameters. The following diagrams shows both possibilities (Slot 1 -> RX, Slot 2 -> TX).
The menu structure depends also if the chassis is configured in single or in master/slave mode. The structure is shown in the two diagrams below. The first one shows the menu structure of a single unit, the second shows the structure of a master/slave unit.
The FAULT sub menu shows you the state of every slot. The MEASUREMENT sub menu gives an overview over the actual measurement values for every slot. The SETTINGS sub menu lets you view and modify the operational parameters of the LFTX/RX. The SETUP sub menu contains a number of parameters which usually only need to be changed during the installation of the optical link.
For further information about the parameters see the chapters Operational Parameters and Installation Parameters of this manual.
