1 INTRODUCTION
This document provides the basic description, application and configuration for Bravo Tech Inc.
mBSC081921-12 system. Throughout this publication,
2 THOERY OF OPERATION
2.1 System Overview
mBSC081921-12 is the economic and convenient coverage solution of DAS system which has a
fiber transport. The system consists of HU (Host unit) and RU (Remote unit). The HU is mounted in a
19” rack and are intend for use indoor environment. The RU can work in outdoor environment. The
output power of the RU is 40W. The transport between HU and RU is fiber optic. The downlink and
uplink optical signal are duplex so there is only one fiber needed.
2.2 Basic System Components
The basic components of Bravo Tech Inc. mBSC system and their functions are shown in Figure 2-1.
A basic mBSC system consists of a Host Unit (HU) and a Remote Unit (RI). The Host unit has
multiple slot assembly that mounts in a standard equipment rack. The RU consists of multiple
electronic and optical modules for supporting multiple Standards, which mounts in outdoor wall or
pole. Control and monitoring functions are provided by the Network Management System (NMS).

2.3 Host Unit Description
The HU, shown in Figure 2-3, consists of RF conditioning units (BIU) and optical TRX modules (FIU).
HU combines the 3 band downlink RF signals from BTS and converters them to optical signal. At the
same time, HU converts the uplink optical signals to RF signals and splits and filters out 3 band RF
signals.

The Network Management System (NMS) is a software-based network management tool that
provides control and monitoring function for Bravo Tech Inc. mBSC system. NMS is used to
provision and configure new system for operation, set the system operating parameters, get system
alarms and status messages and upgrade the system software.
3.1 Software Installation
NMS software CD-ROM will be provided to the customer with product package. Software installation
consists of inserting CD-ROM in the server system of the customer.
3.2 System Start-Up Procedure with NMS
1. Open the NMS software. The NMS Log-In window will open as shown in Figure 3-1 and Figure
3-2. For setting or changing system operating parameters, the advanced login is required. (Check
the box left side of “Advance” for advanced user.)
Caution: To configure the system and set the system paremeters, it should be required
to log in as Advanced User.

6. After configuring the District, the equipment should be defined. Check the Equipment title and
new information sections will be appeared as shown in Figure 3-8. Host Unit should be defined
first before adding Remote unit. Check the MU title and type the information for Host Unit. After
filling the information, click the Add button. Figure 3-9 shows the result for adding Host Unit in the
system configuration.

Caution: When the system was shipped out, the IP address was pre-defined with
default. The customer should changed HU IP address with user defined one.
• Note: the IP address of Host Unit is pre-defined when the product is shipped to the
customer. The customer can change the default IP address of HU to user defined IP
address.

There is the rule to define the Equipment Code for Remote Unit.
Warning: Equipment Code for RU should be followed the numbering rule for normal
operation. The conflicted Cdoe may casue for the failure of configuration of the system.
• The code will be defined with the combination of Slot ID and Port number for FIU
module in Host Unit as shown in Table 3-1. Maximum 6 FIU modules can be installed in
one HU. And the slot number is started with “1” from the left side module to right side
module.
