 NT7D16 Data Access card

In Large Systems, the DAC is fully supported in IPE modules. These special 
slots on the DAC have 24-pair cables pre-wired to the Main Distribution 
Frame (MDF) in card slots 0-15. Any IPE slot will support the first four ports 
on the DAC if connections are made at the MDF. Most IPE modules can be 
upgraded to wire 24-pair cables to the MDF for all card slots.

Note: For directions concerning the pinouts for the MDF, refer to 
Communication Server 1000M and Meridian 1: Large System 
Installation and Configuration (553-3021-210).

Before you begin, power down:

•

the IPE module only, if it is a DC-powered system

•

the entire column, if it is an AC-powered system

It is recommended that you begin the installation from the right hand side 
(when facing the backplane), starting with slot 0 and moving towards slots on 
the left side. If you wish to add more than six DACs, and require slots 8 
through 15, remove the input/output (I/O) panel. Be aware that a full shelf 
installation can take up to 3 hours. You need the following equipment to 
upgrade the cabling:

•

A0359946 Amphenol cables

— These connectors include all the connector and screw apparatus.

— You need one cable for each DAC.

•

cable ties

•

wire cutters

•

A3/16 nutdriver

To support the 24-pair requirement of the DAC, some cabling may need to be 
upgraded (Table 162). See “Upgrading systems” for more information.

Ports 0, 1, 2, and 3 of the DAC work in any standard 16-pair IPE slot (connect 
directly to the MDF).
