in any card slot in the network bus.

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” on
page 340 for DIP switch setting).

The 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
