2. Technical Explanations 2.1 System Composition See figure 2.1-1. Figure 2.1-1 System Composition of RS-5180 Transmission of uplink and downlink signals: RF Master Unit receives the downlink signal from the BTSs of CDMA800 and CDMA1900. After combines, they are then changed to optical signals through the optical interface unit and transmitted to the Remote Unit through optical fiber. After changed to RF signals through Remote Unit, they are finally transmitted to Mobile handsets by antenna.
divided by the master unit, they are transmitted to CDMA800 and CDMA1900 BTSs. 2.2 System Features n CDMA800/1900 dual band indoor optical fiber distribution coverage. n Since optical fiber is the transmission media, it overcomes the drawbacks of indoor RF routing difficulty and high loss. n Plug and play system structure and flexible volume configuration can satisfy different coverage requirements. n Coverage end unit is small in size.
There are 4 downlink RF output ports and 4 uplink RF input ports on the front panel of the Master Unit. Downlink and uplink are connected with 4 Interface Units through RF cable as shown in figure 2.3-1. Figure 2.3-1 Master Unit Panel Diagram (1) Interface Unit (RS-5180-F) Functions of Interface Unit include: uplink optical and electric conversion, showing the alarm signal from Remote Unit and downlink optical dividing output.
Optical connection has trouble, the Remote Unit’s indicator light will automatically goes off. Then the correspondent indicator on the panel of Interface Unit will be off. The indicators next to the uplink optical signal in port on the panel correspond to the Remote Unit connecting with. Figure 2.3-3 Alarm Unit Panel (2) Alarm Unit (RS-5180-MC) When any Remote Unit (Interface Unit) has trouble, it will be indicated in LED and BTS external alarm. It can also be checked through RS 232 interface.
Panel explanations: As shown in figure 2.3-3. RS-232 (BD9): standard RS232 port, used to connect notebook computer. Set and read parameters, status check. The accompany digital port is designed for using in set up only, not for daily operation and after set up no cable will be attached to this port. COMM (RJ45, 8-pin): communication unit port, used to connect communication unit to actualize remote monitor.

3. System Installation 3.1. Installation of Master Unit 3.1.1 Dimensions Master unit rack is a standard 19 " “portable frame ”. Its external dimensions are as follows: W H 564mm D 800mm 380mm Distance between screw fixing holes on the base of the rack are: Left to right: 524 mm Front to back: 322 mm 3.1.2 Space Requirements Master unit should be located indoor so that the space for maintenance and ventilatio n is ensured.
separately in boxes. The “portable rack” for installation of master unit cabinet (standard 19" portable frame 800mm high) is put after disassembled. Therefore, before install master unit, first assemble portable rack. Assembly of Portable Rack It is quite simple to assemble portable rack as shown in figure 3.1-1. The followings should be noted: (1) For the convenience of installation, all the assembly holes on all the components have sufficient room.
Figure3.1-1 Assembly Diagram of Portable Frame Insertion of M5 Nut Cramp In order to fix the master unit cabinet, master unit cabinet supports and tail fiber tray, M5 nut cramps should be pre-inserted onto the two columns of portable frame. Figure 3.1- 2 shows the inserting points-small black square holes, symmetrical on each column. At the back of the columns (i.e.

Installation of Portable Frame Well-assembled portable frame can be installed vertically on the ground. Portable frame can be installed in three ways: A Vertically fixed on the ground; B Vertically fixed on the wall support; C Vertically fixed on table. A Installed on the ground: (1) C hoose the appropriate position indoors. Place the portal frame vertically on the ground. Mark down the points of four φ13 holes. (2) Drill 4 holes with electric impact drill and embed four φ 10 x8 0mm expansion screws.
B Installed on the wall support: 1 For the convenience of marking the fixing holes on wall, first assemble a baseplate and two wall support as shown in the Repeating End Installation Schematic Diagram (B) (figure 3.1- 5) to form the baseplate-wall support component. The baseplate should be removed from the well-assembled portable frame. Note: Put the portable frame with baseplate removed horizontally on the ground, not vertically, to ensure safety. 2 Choose an appropriate place on wall.
C Installed on table: The table on which portable frame will be installed on must be quite stable. The installation procedures are the same as those of installation on the ground. Figure 3.1-5 Master Unit Installation Schematic Diagram (B) Installation of Master Unit: Master unit should be installed as follows: 1 Master Unit is in the master unit cabinet (19 " 6U standard cabinet). Check whether the fixing screws on the panel of Master Unit has loosened in the transportation.
them. 2 Pla ce the well- assembled master unit into portable frame onto the master unit cabinet support. Fix the master unit stably on the portable frame with M5 screws through the fixing holes on the ears of the master unit cabinet. 3 Put the tail fiber tray (2U sliding cabinet) (used to put tail fiber) under the master unit cabinet. Also fix it with M5 screws through the fixing holes on the ears of the cabinet. Fixing holes are hole 18 and 20. 4 Then connect cables in turn. 3.2.

4.1.1 Connection with RF from BTS In connecting RF signal from microcellular or BS, first confirm that the downlink signal from BTS is ≤ 20dBm, otherwise, System may operate abnormally or circuit may be damaged. Optimum downlink signal level input into the port connected with GSM BTS or 1800 BTS (14 and 15 in figure 4.1-1): +5 ~ +20dBm. The maximum input should not be greater than 20dBm. +10dBm is suggested.

1800 > 0d B m. When one of them is off, it means that the input level of the correspondent one is smaller than this normal value. If only GSM 900MHz or CDMA1900Hz needs to be opened, 50 standard load should be connected with the RF connector not in use. Then, the correspondent uplink gain adjustment thumb wheel does not function and the correspondent downlink RF power LED indicator is off. 4.1.
4.1.3 RF Connection Between Master Unit and Interface Unit RF connection between Master Unit (figure 4.1- 1: 1) and Interface Unit (figure 4.1- 1: 2 ) should be done with upper and lower parts corresponding with each other: 6 with 7 and 5 with 8. 4 pairs of fiber-optic connectors (SC optical flange) -EOWN OPOUT (figure 4.1- 1: 9)/UP OPIN (figure 4.1- 1: 10) are on the panel of the Interface Unit. Connect the uplink and downlink optical fibers from the coverage end with these fiber optic connec\ctors.
4.2. Remote Unit 4.2.1 Connection with RF Cable and Optical Fiber figure 3.2-1: Remote Unit Installation Schematic Diagram . Remote Unit has 4 antenna ports at the top of cabinet for antenna connection. Connect 50 standard load for any additional port; downlink fiber- optic input port port (left) and uplink fiber -optic output port port (right) are at the bottom of cabinet, fiber-optic connector is SC fiber-optic adapter. 4.2.
5. User Safety Information To ensure pers onal safety and the normal operation of System, please pay attention to the following: 5.1 System Grounding Well Housings of both master unit and Remote Unit have protective ground terminals. In installation, use yellow and green dual color lead to ground well with building protection ground. Or use ground woven wire. 5.2 Confirming Power Supply Both master unit and Remote Unit use AC power supply of public electricity. Rated voltage range is 100~250V.
5.6 Downlink signal level input from BS +20dBm When connecting RF signal with microcellular or BS, be sure that the downlink signal level from GSM BTS and 1800 BTS be less than or equal to +20dBm (+10dBm is suggested), or the System may work abnormally or even the circuit may be destroyed.
