326 NT5D97 Dual-port DTI2 PRI2 card
CPU capacity
Using a NT5D97 DDP2 card instead of DTI2/PRI2 cards does not
increase the load on the CPU. The DDP2 replaces an ENET card and two
DTI2/PRI2 cards. Emulating the ENET card and the overall CPU capacity
is not impacted by using a DDP2 card instead of a DTI2/PRI2 card.
Power requirements
Table 124 "NT5D97 DDP2 power requirements" (page 326) lists the power
