Case 1 - The two ports of a QPC414 network card are connected to two digital
trunks.
In this case, the QPC414 and the two digital trunks are replaced by a single
DDP2 card, which is plugged into the network shelf in the QPC414 slot.
Case 2 - One port of the QPC414 card is connected to a digital trunk, and the
second is connected to a peripheral buffer. Both cards are in network loop
location.
In this case, the QPC414 should not be removed. The digital trunk is removed
and the DDP2 card is plugged into one of the two empty slots.
