RGPS Cabling for Multiple BTS Sites
DRAFT
SC300 1X BTS Hardware Installation, ATP, and FRU Procedures
JAN 2002
4-24
Objective
This procedure gives information to connect multiple BTS sites for both
RGPS (synchronous) and HSO (non–synchronous) configurations in
both indoor and outdoor applications.
Background
The RGPS only connects to the first unit of a multi–unit logical BTS.
This first unit sends timing signals to all other units. You only need to
connect the site I/O interfaces of each multi–unit logical BTS to each
other. This allows “sharing” of a single RGPS antenna between several
single or multi–unit logical BTSs.
This also applies to systems using HSO instead of RGPS. The HSO
timing is “shared” in the same way.
