The connection of the optical cable varies according to the type of BSC interface board.
If the BSC interface board is the GOIUA/GOIUB/GOIUP, the optical cable between the BSC interface board and the ODF must be connected according to Figure 1.
If the BSC interface board is the GOGUA/GOGUB, the optical cable between the BSC interface board and the ODF must be connected according to Figure 2.
If the BSC interface board is the GOIUT, the optical cable between the two GOIUTs must be connected according to Figure 3.
