BTS architectures and interoperability
M-Cell 6 and
Horizon
macro
architectures
Figure 3-1 represents the high level architecture of the M-Cell 6 and
Horizon
macro BTSs. Both systems provide an optical interface for connection to
remote transceivers, which in a normal installation would be used to connect to
transceivers of the same product type.

However, since the optical interface is identical for both products, it can be used
to link an M-Cell
6 to Horizon macro transceivers, or a Horizon macro to M-Cell 6
transceivers. The principle is shown in Figure 3-2.
