Case Scenarios
The following are case scenarios for the replacement of a digital trunk
NT8D72BA, QPC536E, or NTCK43 by a DDP2 card.
The following discussion describes possible scenarios when replacing
a digital trunk NT8D72BA PRI2 card or QPC536E DTI2 card or NTCK43
Dual PRI card configuration with a NT5D97AD DDP2 card configuration.
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 will have to be reassigned, so that each
pair of buffers will use both ports of the same QPC414 card. The other
QPC414 card can then be replaced by the NT5D97AD DDP2.
