DBS Manual - Revised April 2000
DBS-2.3/9.2-300
Trunk and Line Expansion
Guidelines
• 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.
Installation
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.
