Intercabling Connections
Primary Control Channel Redundancy Intercabling
On a cavity combining RFDS, additional signaling connections must be
made for Primary Control Channel (PCCH) redundancy. There is a PCCH
redundancy control cable for each RF Cabinet used in the system.
The red wire is routed to RF Cabinet 1, the blue wire is routed to RF
Cabinet 2, and the green wire is routed to RF Cabinet 3. RF Cabinets 2 and 3
are used only in sectored sites. All of the PCCH redundancy control wires
(red, blue, and green) branch from the Control modular cable connection on
the rear of the EAS/EAS2.
1.
On the EAS/EAS2, locate the modular cable that is plugged into the
Control connector.
The end of this cable contains three separate branched wires that are
colored red, blue, and green.
2.
Locate the Mate-N-Lok connector at the end of a colored wire.
This is a PCCH redundancy control connection for a specific RF
Cabinet.
Note:
Make sure that each wire is routed to the appropriate RF Cabinet.
Red is for RF Cabinet 1, blue is for RF Cabinet 2, and green is for RF
Cabinet 3.
3.
Route each colored wire to the appropriate RF Cabinet.
4.
In the RF Cabinet, locate the loose cable containing another
Mate-N-Lok connector.
This cable is connected to the antenna relay on the rear of the RF
Cabinet and to the Auxiliary connector on the BR backplane.
5.
Connect the two Mate-N-Lok connectors from the EAS/EAS2 and
RF Cabinet together.
6.
Repeat this procedure for additional RF Cabinets, if necessary.
