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
DDP card, which is plugged into the CE 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 the network loop
location.
In this case, the QPC414 should not be removed. The digital trunk is removed
and the DDP card is plugged into one of the two empty slots.
Case 3 - The CE 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 re-assigned, 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 NT5D12 DDP.
Note in all cases - If a QPC720 card is being replaced by a DDP card, the
D-channel Handler or MSDL can be either reconnected to the DDP card, or
removed if an onboard NTBK51AA DDCH card is used.

NT5D12 switch settings

The NT5D12 card is equipped with 6x2 sets of DIP switches for trunk
parameters settings for port0 and port1 respectively. Additionally, the
NT5D12 card is equipped with one set of four DIP switches for the Ring
Ground setting and one set of eight DIP switches for the D-channel Handler
parameters setting.
The DIP switches are used for setting of default values of certain parameters.
The general purpose switches are read by the firmware which sets the default
values accordingly.
The following parameters are being set by the DIP switches. Factory setups
are shown in bold.
