Confidential & Proprietary                   9/99 “Only qualified personnel are allowed to handle this unit. Read and obey all the warning labels attached in this user manual”     Any personnel involved in installation, operation or service of the SOLiD Technology repeaters must understand and obey the following: - Obey all general and regional installation and safety regulations relating to work on high voltage installations, as well as regulations covering correct use of tools and personal protective equipment. - The power supply unit in repeaters contains dangerous voltage level, which can cause electric shock. Switch the mains off prior to any work in such a repeater. Any local regulations are to be followed when servicing repeaters. - The repeater cover should be (door) securely fastened in open position, e.g. by tying it up, at outdoor work in order to prevent door from slamming due to wind causing bodily harm or damage. - Use this unit only for the purpose specified by the manufacturer. Do not carry out any modifications or fit any spare parts which are not sold or recommended by the manufacturer. This could cause fires, electric shock or other injuries.   - Any repeater, including this repeater, will generate radio signals and thereby give rise to electromagnetic fields that may be hazardous to the health of any person who is extensively exposed to the signals at the immediate proximity of the repeater and the repeater antennas.   - Due to power dissipation, repeater may reach a very high temperature. Do not operate this unit on or close to flammable materials.   - Do not use any solvents, chemicals, or cleaning solutions containing alcohol, ammonia, or abrasives. - Certification   z  FCC: This equipment complies with the applicable sections of Title 47 CFR Parts 15,22,24 and 90 z  UL/CUL: This equipment complies with UL and CUL 1950-1 Standard for safety for information technology equipment,including electrical business equipment z  FDA/CDRH: This equipment uses a Class 1 LASER according to FDA/CDRH Rules.This product conforms to all applicable standards of 21 CFR Chapter 1, Subchaper J, Part 1040

Confidential & Proprietary                   11/99 2.1 General overview SMDR-NH124 is a coverage system for in-building services delivering voice and data in high quality and for seamlessly. As a distributed antenna system, it provides analog and digital phone systems that are served in multiple bands through one antenna. The system covers general public institutions and private facilities. z Shopping malls z Hotels z Campus areas z Airports z Clinics z Subways z  Multi-use stadiums, convention centers, etc. The system helps improve in-building radio environments in poor condition and make better poor RSSI and Ec/Io. By providing communication services at every corner of buildings, the system enables users to make a call at any site of buildings.   The system uses both analog (AMPS) and digital (TDMA, CDMA and WCDMA) methods. The SMDR-NH124 system supports communication standards and public interface protocols in worldwide use. z  Frequencies: VHF,UHF, 700MHz, 800MHz,850MHz 900MHz,1900MHz,2100MHz, etc.   z  Voice protocols: AMPS,TDMA, CDMA,GSM,IDEN, etc. z  Data protocols: EDGE,GPRS,WCDMA,CDMA2000,Paging, etc. SMDR-NH124 is in modular structure per frequency. To provide desired frequency in a building, all you need to do is to insert a corresponding frequency module into each unit. As it delivers multiple signals with one optical cable, the system, in one-body type, does not require additional facilities whenever new frequency is added. The system is featured with the following: z  Flexibiltiy & Scalabiltiy   Support fiber-optic ports up to 39   Clustering multiple-buildings (campus) as one coverage z  Modular structures   Modular frequency upgrade     Plug-in type module   z Multi-Band, Multi Operator
Confidential & Proprietary                   12/99   Signals with a plurality of service provider transmit simultaneously       Support multi-operator in a band   z  Low OPEX / CAPEX  Compact design   Upgradable design    Easy installation and maintenance   Web Based SNMP or GSM Modem or UDP support (Optional) 2.2 System overview SMDR-NH124 is composed of devices given below. Basically, the system consists of BIU (BTS Interfcace Unit), ODU (Optic distribution Unit) and ROU (Remote Optic Unit). For addition of more ROUs, it has OEU (Optic Expansion Unit).

DC Input Port  Input terminal for DC -48V 4.2  ODU (Optic distribution Unit) ODU receives TX RF signals from upper BIU and converts them into optical signals. The optical signals are sent to ROU through optical cables. This unit converts optical signals from ROU into RF signals and sends the converted signals to BIU.   For each shelf of the ODU, up to two DOUs (Donor Optic Unit) can be installed in it. One DOU is supported with four optical ports. Therefore, one ODU can be connected with eight ROUs.  Up to four ODUs can be connected with BIU.
