MASTR V BASE STATION OVERVIEW
4.1
MULTI-CHANNEL BASE STATION SHELF ASSEMBLY
The MASTR V multi-channel base station shelf assembly is a unified subrack design providing 14
identical vertical module slots. Also included are two (2) horizontal slots located under the 14 vertical
slots, and used to connect the built-in main and redundant Ethernet Switch modules.
A backplane assembly (refer to Figure 4-2) provides data and DC power connections to each vertical slot,
and the two Ethernet Switch module slots. The multi-channel base station shelf, and each module, is
equipped with a pull handle for improved handling of the equipment.
When equipped for multiple channel VHF, 150-174 MHz operation, the 14-slots may be populated as
shown in Figure 4-1 with the modules listed in Table 4-1. Other module combinations and slot
assignments are possible depending on the specific LMR application and system requirements.
