2.4.5 CPP (Centric Patch Panel)
The VigorAccess can provide ADSL and voice services over the same telephone wiring.
It also has built in splitters internally that can save space and simplify installation.
If the application is using on building environment, the CPP (Centric Patch Panel) is
preferred.
The purpose of CPP module is to transfer RJ-21 jack in VigorAccess to
RJ-11 connector. It is usually installed between end-users’ equipment and telephone
company in a basement or telephone room. The CPP is the point of termination for the
outside telephone company lines coming into a building and the telephone lines in the
building.
The existing telephone wiring usually depends on user’s region. Here are descriptions of
two typical installation scenarios. Use telephone wires with RJ-11 jacks on one end for
connecting to the CPP board.
Scenario A
Users can connect a cable from RJ-21 (LINE) attached in VigorAccess to the CPP board.
Then users can connect a RJ-11 jack port attached in a CPP to ADSL modem directly.
The following example shows the connection for
data transmission only through CPP.
