3.2 Host Unit Description
As shown in Figure 4, the Host Unit is a standard 19”4U rack-mounted shelf, which serves as the BTS
servicing unit for the mBSC system. The Host Unit provides the following basic functions:
RF interface with BTS (Simplex TXin, RXout)
Optical interface to Remote Nodes
Conversion of the forward path(downlink) RF signals into up to four simulcast optical signals
Conversion of up to four reserve(uplink) optical signals to RF signals
Manages and monitors the system alarms and configurations
Provides alarm information to a local alarm or remote system

3.2.1 Host Unit Components
The Host Unit is a multi-slot chassis, consisting of 9 slots numbered from left to right: 1 through 9. Slots 7
through 9 are dedicated and specifically keyed for the Remote Control Unit (RCU) and two redundant Power
Supply Units (PSUs). The Host Unit also houses the Base Station Interface Units (BIU) and Fiber Interface
Units (FIU). The Host Unit allows any combination of BIU and FIU modules, up to six in total.
3.2.1.1 BIU (BTS Interface Unit)
The BIU is a frequency agnostic RF interface card that provides simplex TX input and RX output
connections to the BTS equipment. The BIU combines up to 5 bands of RF downlink signal into a composite
signal, which is then split across four TX out connectors for interconnection to up to four fiber modules
(simulcast). In the uplink path the BIU combines up to four separate multi-band uplink signals for distribution
