NT5D97AA/AB DIP switch settings 129
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 NT5D97 DDP2.
Note: If an NT8D72BA/NTCK43 card is being replaced by a DDP2
card, the D-channel Handler can be reconnected to the DDP2 card, or
removed if an onboard NTBK51DDCH card is used. Also, DIP Switches
in the NT5D97 must be set properly before insertion. NT5D97 has a
different DIP Switch setting from NTCK43AB. Refer to
"NT5D97AA/AB
DIP switch settings" (page 129) for DIP switch setting).
NT5D97AA/AB DIP switch settings
The NT5D97 DDP2 card is equipped with 6x2 sets of DIP switches for
trunk parameters settings for port0 and port1 respectively. Additionally,
the DDP2 card is equipped with one set of four DIP switches for the Ring
Ground setting. The NT5D97AA/AB has one set of eight DIP switches and
NT5D97AD has two sets of ten DIP switches for the D-channel Handler
parameters setting.
The DIP switches are used for the setting of default values of certain
parameters. Firmware reads the general purpose switches, which sets the
default values accordingly.
