2.2 Cartridge
In accordance with the IEC60297 standard, the cartridge is 19 inches in width and 7U in height. Each
cartridge can accommodate four CHUs, two BSCUs and two PSUs
The slot 5 and slot 6 of the main chass is are available for the BSCU. See Figure 2-5.
Figure 2-5 Full Configurat i on for MC
.
2.3 Channel Unit (CHU)
The CHU logically includes power amplification, TX excitation unit, baseband signal processing unit
and diversity receiver. See Figure 2-6.
2.3.1 Function
The CHU processes and converts protocols on the physical layer and data link layer of the DMR air
interface. Physically, it consists o f channe l contr ol boar d (CHB), TX boar d (TX B) and RX board (RX B).

CHB: capable of signaling processing, channel encoding/decoding, interleaving and de-interleaving,
modulation/demodulation, RF signal loop-back test and fail-soft.
TXB: capable of modulation, upward frequency conversion, filtering and D/A conversion from carrier
baseband signal to RF signal, as w ell as the downlink signal ampl ification.
RXB: capable of filtering, demodulation, downward frequency conversion, AGC and A/D conversion
from three-path carrier signal to baseband signal, as well as uplink signal a m plification.
