Gen 3 Site Controller System Manual Chapter 4 Installation
Intercabling Connections
■ In sectored sites with multiple RF Cabinets serving a single sector, do not
drive all cabinets within a single sector from the same output.
The following examples illustrate possible RF Cabinet 5 MHz/1 PPS
intercabling that balances the BR load and provides site reference output
redundancy within a sector.
Example 1 — Assume a 24-BR, three-sector site consisting of the
following arrangement:
■ 12 BRs in Sector 1
■ 8 BRs in Sector 2
■ 4 BRs in Sector 3
The table below shows a proper distribution of the site reference outputs to
the RF Cabinets (RFCs).
Note that in the above example, each output drives 8 BRs, while utilizing all
three outputs within sector 1.
Example 2 — Assume a 16-BR, two-sector site with the following
arrangement:
■ 8 BRs in Sector 1
■ 8 BRs in Sector 2
The table below shows a proper distribution of the site reference outputs to
the RFCs.
Note that in the above example, each output drives eight BRs, while utilizing
two different outputs within a given sector.
