Setting up the NTAG54AA

The NTAG54AA is a dual (two port) daughterboard version of the
NT6D11AF to support DPNSS1/DASS2 applications with the Dual PRI
card (NTCK43AB vintage or higher). It is dual density, that is, it replaces
two NT6D11 D Channel handlers, and supports two addressing modes:
•
NT or standard mode: 128 I/O ports though only 16 unique addresses
are supported by the current software;
•
GPT or extended addressing mode: 160 ports available though there
is a limit of 40 addresses.

NTAG54 installation and removal

Note to installers
Before beginning an installation, do the following:
•
Consult the Spares Planning (NN43001-253) document and follow the
instructions.
•
Bring spares of all cables and boards.
•
Remember that test procedures require a 24-hour minimum bit
error-rate testing before being used. See the ISDN Primary Rate
Interface: Features (NN43001-569) or ISDN Basic Rate Interface:
Features (NN43001-580) document for these test procedures.
•
Either the NTAG54 or the DPRI card may be installed first. However,
DPRI loops must be configured in software before defining DCH links.
CAUTION
Service Interruption
The NT5K35, NT5K75, or NT6D11AE/AF DCHI must be
software disabled before it is hardware disabled, or initialization
will occur.
