FMU is applicable to multiple types of BTS. It can be installed in the big or small fan frame in the cabinet. The data cable of big fan is connected to J1 on FMU, and the small one to J8~J11 (their designations are FAN1~FAN4).

J5 and J6 are only used for the cascading of BTS30. J5 is the input socket, and J6 is the output socket. When the BTS30 is cascading, the J6 on the FMU of the lower level BTS30 should be connected to the J5 on the FMU of the upper level BTS30 to realize the transmission of the power signal and alarm signal.

The function of the DIP on FMU is listed in Table 1-17.

Caution:

The DIP settings of FMU have already been finished before delivery. Therefore, do not change the settings unless necessary.

FMU is located in the big or small fan frame. Its DIP can be seen after pulling out the fan frame.

1.15 RCDU

The RCDU is the same as ECDU in terms of structure, functions, peripheral interfaces, peripheral interface dimensions, and maximum input power. It can combine transmitted RF signals, divide received RF signals and implement reception and transmission duplex. The difference between RCDU and ECDU lies in the bands supported. The bands supported by RCDU ranges from 876 MHz to 901 MHz (uplink) and 921 MHz to 946 MHz (downlink). For the BTS working at the EGSM band with the frequency range of 880 MHz to 890 MHz (uplink) and 925 MHz to 935 MHz (downlink), The RCDU is optional.

1.16 REDU

The REDU is the same as EDU in terms of structure, functions, peripheral interfaces, peripheral interface dimensions, and maximum input power. It can implement 1-to-2 division of received signals and implement reception and transmission duplex. The difference between REDU and EDU lies in the bands supported. The band supported by REDU ranges from 876 MHz to 901 MHz (uplink) and 921 MHz to 946 MHz (downlink). If the BTS works in the EGSM band with the frequency range as 880 MHz

The digit 1 of DIP represents the matching setting of the combining control signal CBUS1. If digit 1 is set to “ON”, it indicates matching setting. If digit 1 is set to “OFF”, it indicates unmatched setting.

If no cabinets are combined, digit 1 must be set to “OFF”. If two cabinets are combined, digit 1 on both cabinets must be set to “ON”. If three cabinets are combined, digit 1 of the two DIPs of which the cabinets has the most distance are set to “ON”, and the digit of the medium cabinet is set to “OFF”.

If no cabinets are combined, digit 3 must be set to “OFF”. All the digits of S7 on TCB are set to “ON”. This indicates that the BTS clock in this cabinet is directly driven by the TMU in this cabinet.

In combined cabinets, digit 3 is set to “OFF”. And all digits of S7 on TCB are set to “OFF”. This indicates that the BTS clocks of all the combined cabinets are driven by TCU in this cabinet.

Digit 4 is set to decide whether the TMU clock in this cabinet can be enabled in TCU. If digit 4 is set to “ON”, it indicates that the TMU clock is disabled in TCU. If digit 4 is set to “OFF", it indicates that the TMU clock can be enabled in TCU.

If no cabinets are combined, digit 4 must be set to “ON”. All the digits of S7 on TCB are set to “ON”. This indicates that the TMU clock is directly sent to the TRX in this cabinet instead of entering TCU.

In combined cabinets, digit 4 in the primary cabinet is set to “OFF”. This indicates that TMU clock in this cabinet can drive the TCU in the same cabinet. Digit 4 in the secondary cabinet is set to “ON”, this indicates that the TMU clock cannot drive the TCU in the same cabinet.

And all digits of S7 on TCBs in both the primary and secondary cabinets are set to “OFF”. This indicates that the BTS clocks of the primary and secondary cabinets are driven by TCU.

All OFF All ON E1 cascading (default setting)

All ON All OFF Optical fiber transmission (referred to the optical transmission mode mentioned in Note 2 below.

Note:

BTS3001C provides two optical transmission modes: In physical, transmission between multiple BTS3001Cs via optical fiber. When

allocating services on the link, each BTS3001C service occupies a 2M line. The connection mode is the same as the star networking between BTS and BSC by E1. In this mode, multiple BIE (Base station Interface Equipment board) ports on BSC are occupied.

In physical, transmission between multiple (2~5) BTS3001Cs via optical fiber. When allocating services on the link, all BTS3001C services share the same 2M line. The connection mode is the same as the chain networking between BTS and BSC by E1. In this mode, only one BIE on BSC are occupied.

If BTS3001C adopts the first mode, the settings of S10 and S11 should adopt the default ones. If BTS3001C adopts the second mode, it is necessary to change the default settings of S10 and S11.

Note:

BTS3002C consists of three modules: Main Control Unit (MCU), Power Supply Unit (PSU) and Digital and Radio frequency Unit (DRU).

Note:

MCU has two hardware versions: REV.0 and REV.B. The cavity, indicators and interfaces of the two versions are all the same. However, the MCUs of the two versions are greatly different in the meaning of partial DIP switches. Hereinafter, unless otherwise mentioned, the description of the DIP switches is applicable to both versions.

To obtain the hardware specification (REV.0 or VER.B) of the MCU, you cannot identify from the MCU appearance but have to query the MCU information through the maintenance console of the BTS3002C.
