Introduction to interoperability
Mixed product
sites
This chapter describes how the Horizon macro 6 carrier outdoor can be used in
conjunction with other Motorola BTS products.
Different Motorola product types can be collocated at the same physical site
without restriction, provided they are configured as logically separate
installations, and in accordance with the normal product engineering rules.
When mixed product types are installed at the same logical site , a number of
technical issues arise that restrict the hardware that can be configured, and the
way it is interfaced. This chapter explains which product types can be mixed in
this way, and how they are interfaced.
Architectural
constraints
To enable different product types to be used at the same logical site, one
product type is chosen as master , which is connected to the extender equipment
so that the two product types can function as a single, logical BTS. This
approach is viable when the product types to be interfaced have similar
architectures.
Motorola BTS product types that can be interfaced for collocation at a single
logical site are therefore restricted to those shown in Table 6-1 below.

Indoor and outdoor cabinets can be mixed, but different mechanical
arrangements may be required for routeing the inter-cabinet cabling.

NOTE
This chapter only applies to the Horizon macro GSM/
EGSM900 and DCS1800 BTS variants.
GSM850 and PCS1900 Horizon macro BTS variants
cannot be mixed with other Motorola BTS types.
