22CHAPTER 2: INSTALLING THE VCN ACCESS CONCENTRATOR

The VCN AP punch-down block, which carries both data and voice, can be connected to an optional patch panel, which connects the circuits between the VCN AC and punch-down blocks.

If there is no patch panel, the VCN AC unit connects directly to the VCN

AC punch-down block and VCN AP punch-down blocks.

The VCN AC unit should be installed at the PBX punch-down block location, usually in the basement or wiring closet of a building.

The unit is installed in a 19-inch rack along with the SuperStack II Switch 1100/3300 and an optional patch panel.

There are two methods for installing the Visitor and Community Network system:

■With a patch panel.

■Without a patch panel.
