• The EC/TRK slot can be used for a trunk or extension card. 

• Different expansion connectors are used for trunks and extensions:

Note: With the DBS 96, the expansion connector is not required to use 
the EC/TRK slot for an extension card. The DBS 96 uses connector CN14 
to accommodate an extension card in the EC/TRK slot. Table 4-22 on 
page 4-35 shows the pinouts from the EC/TRK slot to CN14.

1.  Install a trunk or extension card in the slot marked EC/TRK.

2.  Connect the appropriate expansion connector to the main cabinet with 

two screws, as shown in Figure 4-18.  

3.  Connect the ground cable from the FG terminal of the expansion 

connector to a screw already in use on the right side of the main cabinet.

4.  Connect CN2 of the expansion connector to CN15 on the mother board.

5.  Prepare a cable with a 50-pin connector on one end and wiring for the 

MDF on the other end.  

6.  Cross-connect the cable to the trunks or extensions through the MDF. See 

Table 4-3 “Pinouts and trunk numbers for trunk expansion connector 
CN1” on page 4-6 or Table 4-23 “Pinouts and color codes for extension 
expansion connector CN1” on page 4-36.

7.  Connect the 50-pin connector to CN1 on the expansion connector.
