Boards
This chapter describes the functions and descriptions of ZXG10 iBSC boards.
Overview
According to the hardware assembly relation, boards can be classified as front board and rear board.
Front board has a front panel. Indicators on the front panel indicate the board status. Front board can be inserted in the slots.
Rear board consists of the external interfaces and debugging interfaces. These interfaces are used to interconnect shelves of same cabinet or different cabinets. The rear board and the front board work together. For some active/standby front board, it is necessary to configure two kinds of rear boards.
Front board and rear board are installed in the slots on the backplane.
Front board and rear board form a complete metal shield inside the shelf, reducing the external electromagnetic radiation of the system and enhancing the anti-interference capability.
Figure 43 shows the board assembly relation.

There are 12 4-digit DIP switches on DTB.
Eight 4-digit DIP switches (S1-S6, S9 and S12) are to select impedance matching resistance for each E1: 75 W or 120 W.
Line impedance is 75 W if DIP switch is set to ON.
Line impedance is 120 W if DIP switch is set to OFF.
Two 4-digit DIP switches (S7 and S8) are to indicate receiving matching impedance of each E1 chip for CPU.
Matching impedance of corresponding E1 is 75 W if DIP switch is set to ON.
Matching impedance of corresponding E1 is 120 W if DIP switch is set to OFF.
Each DIP switch corresponds to one E1 chip:
S7 corresponds to E1 chips 1 to 4 (E1 channels 1 to 16)
S8 corresponds to E1 chips 5 to 8 (E1 channels 17 to 32)
CPU reads this status during power-on and initiates each E1 chip according to this status.
Two 4-digit DIP switches (S10 and S11) are to indicate long/short line status of each E1 chip for CPU.
Corresponding E1 chip (four E1 channels in total) is in SHORT HAUL mode if DIP switch is set to ON.
Corresponding E1 chip is in LONG HAUL mode if DIP switch is set to OFF.
Each DIP switch corresponds to one E1 chip:
S10 corresponds to E1 chips 1 to 4 (E1 channels 1 to 16)
S11 corresponds to E1 chips 5 to 8 (E1 channels 17 to 32)
CPU reads this status during power-on and initiates each E1 chip according to this status.
There is one jumper (X23) on DTB for debugging. X23 must be disconnected when the board is working normally.

Main Control Unit
It is the core of alarm box, which is used to save OS, startup code and voice data. The work library space is 8 MB, and data saving space is 16 MB.
Interface Unit
The external interface of alarm box is as follows:
Ethernet interface
RS232 serial interface

Land Modem interface
GPS interface
Man-machine Unit
It provides hearable and visible alarm information and also provides the operation and maintenance interface.
Alarm Indicator
There are four alarm indicators. Colored red, blue, yellow and green in order of severity. When alarm occurs, the corresponding indicator will flash or be ON for a long time.
Chapter 4 –Boards
Confidential and Proprietary Information of ZTE CORPORATION 119
There is no individual alarm indicator for environment alarm, but it is handled as a certain level alarm.
Voice Announcement
The main control unit works in transparent HDLC mode, it sends the PCM voice saved in FLASH to the PCM coder/decoder chip (CODEC) for coding, and the data is converted to linear signal. Then the power amplifier drives the speaker, and the hearable alarm is realized.
The voice management at background realizes the voice recording, edit and pre-play, and downloads the voice file into the FLASH of the alarm box.
LCD
LCM is employed to display the alarm.
LCD is hung on the parallel bus of the main control unit. LCM size is proper and it is all-dots graphic display. Characters font size is controlled by software to display different type of information.
LED has back facet power, which is generally OFF resulting in increased life of the LED. When pressing the function button or displaying information, the back facet power turns ON to display.
There are some function buttons on the alarm box, which realize the operation and maintenance functions together with LCM.
Logic Unit
Employ EPLD to realize required combinational and sequential logic.
Power Unit
The input voltage of the alarm box is -48 V DC from the equipment room, and is converted to +5 V, +3.3 V and other voltages for each unit by DC-DC power converter.
When the alarm box is in the duty room outside the equipment room, there may not be -48 V DC power, in this case, a external AC/DC power adapter is required to convert 110/220 V AC to 48 V DC, providing -48 V DC power to the alarm box. AC/DC power adaptor is an optional accessory of the alarm box.
