Clock Controller - Option 4
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.
Case 3 - The network shelf is full, one port of a QPC414 network card is
connected to a digital trunk, and the second is connected to a peripheral
buffer. This arrangement is repeated for another QPC414. The digital trunks
are located in a shelf that provides only power.
In this case, the peripheral buffers must be re-assigned, so that each pair
of buffers uses both ports of the same QPC414 card. The other QPC414
card can then be replaced by the NT5D97 DDP2.
