Preparing the Site for the VCN Access Concentrator 11
CAUTION:
Installation should be performed only by a qualified
technician
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 Ethernet switch 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.

with a Patch Panel
To install the VCN AP punch-down block when there is a patch panel,
perform the following steps:

Select the wire pairs according to their position in the RJ-11 telephone
connector in the rear of the VCN AP. The two outside wires comprise the
outer wire pair and the two inside wires comprise the inner wire pair, as
shown in Figure 4 and Figure 5.
Where there is only one telephone line in a room, the two wires are
connected to the inner wire pair of the phone connector shown in
Figure 4 and Figure 5. The outer wire pair of the phone connector is not
used.

The inner wire pair carries both voice and digital date.
