Equipment Overview
The SC 4812ET BTS consists of an RF Cabinet that is an outdoor,
weatherized version of the SC 4812T. The RF cabinet is powered by
27 Vdc and each cabinet has the capability to support up to 4 carriers (at
3 sector) or 2 carriers (at 6 sector).
The RF Cabinet houses the fan modules, CCCP, LPA modules, LPA
trunking backplane, Bandpass 2:1 & 4:1 Combiners, Duplexer/Receive
Filter/Directional Couplers (DRDC) and a DC Power distribution
assembly. The Power Cabinet (PC) provides +27 Vdc distribution and
battery backup for the SC 4812ET. The Power Cabinet houses batteries,
battery heaters, rectifiers, an AC Load Center (ACLC), a power
distribution assembly, and two duplexed GFCI convenience outlets.
CCCP Shelf Card/Module Device ID Numbers
All cards/modules/boards in the frames at a single site, assigned to a
single BTS number, are also identified with unique Device ID numbers
dependent upon the Frame ID number in which they are located. Refer to
Table 1-3 and Table 1-4 for specific CCCP Shelf Device ID numbers.
