Port definitions

Since the NT5D97 card is a dual-card, it equips two ports; these ports can be defined in the following combinations:

Table 35

NT5D97AA/AB loops configuration

				Loop 0
			not configured			DTI2		PRI2
Loop	not configured		V			V		V
1	DTI2		V			V		V
	PRI2		V			V		V
Table 36
NT5D97AD loops configuration
				Loop 0
				not configured	DTI2		PRI2	DDCS
		not configured		V	V		V	V
Loop 1

		PRI2		V	V		V	X
		DDCS		V	V		X	V

Note: Each loop DPNSS can be defined in Normal or Extended addressing mode.

Case Scenarios for replacing 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 NT5D97 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 a 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.
