NT5D97 Dual-port DTI2 PRI2 card
Figure 87: 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 reassigned, 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.
Caution:
The static discharge bracelet located inside the cabinet must be worn before handling circuit
cards. Failure to wear the bracelet can result in damage to the circuit cards.
