•Port 0 of the NTBK51AA can only be defined to work with Loop 0 of the NT5D97 DDP2 card, and Port 1 of the NTBK51AA can only be defined to work with Loop 1 of the NT5D97. This relationship must be reflected when configuring a new DCH in LD 17 (in response to the DCHL prompt, enter either 0 or 1 when specifying the loop number used by the DCH).

•You cannot define one of the DDP2 loops for the NTBK51AA DDCH, and the other loop for the NT6D11AF/NT5K75AA/NT5K35AA DCH card or the NT6D80 MSDL.

•When configuring the NT5D97 DDP2 in DTI2 outgoing dial pulse mode, a Digit Outpulsing patch is required.

Testability and diagnostics

The DDP2 card supports testing and maintenance functions through the following procedures:

•Selftest upon power up or reset

•Signalling test performed in the LD 30

•Loopback tests, self tests, and continuity tests performed by LD 60 and LD 45

•The D-Channel (DCH, MSDL, DDCH) maintenance is supported by LD 96.

Note: The MSDL selftest is not applicable to the NTBK51AA D-Channel daughterboard.
