The LO tributaries are then processed in the same way as described in section 3.2.1.2 on page 61, with
a second cross of the LOA card.
It has to be noted that with this particular architecture, the LOA resources physically implemented are
doubled with respect to the total LO traffic, coming from data cards, that has to be processed in the
equipment.
