Dear friend!
A common line processing board is used only to transmit ODUk signals forwarded from the cross-connect board.
The hybrid line processing board can simultaneously transmit ODUk signals and STM-n signals forwarded from the cross-connect board.
The universal line processing board can simultaneously transmit ODUk signals, packet signals, and STM-n signals forwarded from the cross-connect board.
The optical interface rate of the programmable line processing board can be changed through the NMS (with license restriction).
Thanks!
