300 BTS Hardware Installation, ATP and FRU Procedures
PRELIMINARY
Overview
This procedure gives information to connect multiple units for both
RGPS (synchronous) and HSO (non–synchronous) configurations.
Background
The RGPS only connects to the first unit of a multi–unit system. This
first unit sends timing signals to all other units in a multi–unit system.
You only need to connect the first units of each BTS to each other. This
allows “sharing” of a single RGPS antenna between several single or
multi–unit BTSs.
This also applies to systems using HSO instead of RGPS. The HSO
timing is “shared” in the same way.
Required Equipment
