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:

Expansion connector	Part No.
Trunk expansion connector	VB-43120
Extension expansion connector	VB-43121

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 4-35shows 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 4-6or Table 4-23 “Pinouts and color codes for extension expansion connector CN1” on page 4-36.
