The name of all the ports are silk printed as "#1, #2, #3 and #4." Referring to the table above, you need to feed right signals to input and output ports of corresponding MDBU.
Confidential & Proprietary 68/139 For each port, TX signals and RX signals are separated from each other. You don't have to terminate unused ports unless you want to. BIU interface with Base station Transceiver Basically, BIU has different TX and RX ports, and so, you have only to connect input and output ports. Through spectrum, you need to check signals sent from BTS TX. If the signals exceed input range (-20dBm~+10dBm), you can connect an attenuator ahead of the input port to put the signals in the input range. BIU interface with Bi-Directional Amplifier Basically, BIU is in Simplexer type; when you use BDA, you need to separate BDA signals from TX and RX type. Using a duplexer or a circulator, you can separate TX/RX signals of an external device
Confidential & Proprietary 69/139 from each other. Figure 5.2 – 800PS BDA Interface using Circulator Figure 5.3 – 800PS BDA Interface using Duplexer BIU interfaces with BDA in either of the methods above. In this case, you need to check TX input range as well.
Confidential & Proprietary 70/139 Given the TX input range (-20dBm~+10dBm/Total per port), make sure to see if the value is in the input range, using Spectrum Analyzer, when you connect input ports. 5.1.4 MDBU insertion MDBU is designed to let a MDBU be inserted into any slot. BIU can be equipped with a total of four MDBUs. If only one MDBU is inserted into a slot with the other slots reserved, you need to insert BLANK cards into the other slots.
Confidential & Proprietary 71/139 If you do not terminate input and output ports of MCDU, which combines TX signals and divides RX signals, it will cause loss and generation of spurious signals at the other party's band. Given this, make sure to insert MDBU BLANK into slots of MDBU. When MDBU is inserted into BIU, LED at the front panel will show the following information:
Confidential & Proprietary 72/139 MONITOR SMA port seen at the front panel of MDBU enables you to check current level of TX input and RX output signals in current service without affecting main signals. TX MON is -20dB compared with TX Input power and RX MON is -20dB as well compared with RX Output power. 5.1.5 ODU Interface BIU supports up to four ODUs. At the rear of BIU, eight RF input and output ports for ODU and four power ports for power supply and communication are provided. At BIU, you can check installation information of ODU. LED Description Power is not supplied. ON Power is supplied. Normal Operation ALM Abnormal Operation
Confidential & Proprietary 73/139 At the rear part of ODU, the number of RF Ports and Signal Ports are printed in order. Therefore, you need to be careful in case of expansion of ODU. RF Port ODU Numbering TX RX Signal Port ODU 1 #1 ODU-1 ODU 2 #2 ODU-2 ODU 3 #3 ODU-3 ODU 4 #4 ODU-4
Confidential & Proprietary 74/139 If ODU is not connected in the right order, related devices may fail to communicate with each other or the unit may read wrong information. Given this, you need to connect the unit with accurate RF Port and Signal Port in a corresponding number.
Confidential & Proprietary 75/139 For unused RF Ports for ODU expansion, make sure to terminate them using SMA Term.
Confidential & Proprietary 76/139 When you put ODU on the top of BIU, it is recommended to install the unit at least 1U apart from BIU. Heat from BIU climbes up to reach ODU. 5.1.6 Consumption Power of BIU The table below shows power consumption of BIU: Part Unit Consumption Power Remark Shelf Common Part MCDU 7.5 W
