22 CHAPTER 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 b locks.
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.
