JULY 2009 Section 5. System Overview 5.1 Configuration and Features Features Modules comprising TRI-Band Repeater are arranged for operators and technicians to utilize them effectively. The Repeater is basically a wall-mounted structure, and if required it is constructed to be installed on 19 inch Rack. At the bottom of repeater, there are 1 donor port, 1 service port, 1 Donor signal monitoring port, 1 Service signal monitoring port, and AC power outlet.
JULY 2009 5.1.1 PSU (Power Supply Unit) The AC power source is converted through A/D and D/D to feed stable current to each active device. The Repeater adopts industrial equivalent level or above components. It is highly robust physical structure and meets all required electrical specification. Operating power ranges from AC 108- to 127V input and it converts to DC 3.5V, 3.8V, DC 7V, DC 12V and DC 27V for use. 5.1.
JULY 2009 e. UNDER CURRENT: Red light = Alarm / Green = Normal f. POWER: Solid Green = Power On / Blinking Green = Normal h. RESET: Controller Reset Button i. TXD: On = Data transmitting with Web GUI connected Green blinking j. RXD: On = Data receiving with Web GUI connected Green blinking 5.1.3 UP/DOWN Converter Up/Down Converter modules of the Tri-Band RF repeater were realized for iDEN and CDMA respectively.
JULY 2009 Block Diagram for CDMA Digital Filter Up/Down Converter module for iDEN and CDMA suppresses leakage of local signals into the input terminal by inserting a band path filter on the front side of a mixer. The mixer minimizes IMD components of the system by applying elements having characteristics of high IP3 and minimizes influence on the next step by maintaining linearity.
JULY 2009 5.1.5 PAU PAU considers Spurious features to apply degauss with credibility, endurance and high P1dB and inspects at all times output by linking to system’s control part. So when main problem happens, it can be reported to upper level and if required by the user PAU move can be On/Off.

A. Procedure a. Switch ON/OFF ALC function set up through GUI. b. When the down link output value is greater than the set level or 1.5dB less than that in case of CDMA or 1dB less than that in case of i-DEN, the difference shall be compensated. c.
JULY 2009 d. Inspect output for 4 seconds again after waiting for stable output for 1 second. e. Perform c, d and e move for 3 times. f. After 3rd move the PAU ON waiting time is 30 minutes. With Shutdown condition afterward, proceed complete Shutdown state. g. On complete Shutdown state the user should directly switch the repeater OFF or ON, or set up PAU ON to come out of complete Shutdown state. (2) Notes a. Will not function when ALC Operation set up is OFF. b.
JULY 2009 c. Return PAU to original state after 10 seconds to perform oscillation check function. d. On continuous Shutdown condition, try 3 times to enter complete Shutdown state afterward. e. On complete Shutdown state the user should directly switch the repeater OFF or ON, or set up PAU ON to come out of complete Shutdown state. (2) Notes a. Operate when oscillation check function is ON only. User Manual of CDMA RF-Repeater Ver 1.
JULY 2009 Section 6. System Installation Guide The Cabinet of the Repeater is a die-casting structure, which supports wall-mount installation and if required it can be installed in a 19 inch Rack. The Repeater has 4 Wall Mount Holes, which need to be installed properly to sustain the weight of repeater on a wall-mounted installation. The procedure for wall-mounting installation are as follows; (1) Remove Repeater from package. (2) Check the components of repeater.
