Signal interaction between shelves

All resource shelves connect with GLI on the switching shelf via the optical interface on the front panel of UIMU.

The control shelf connects with UIMC on the switching shelf via RCHB1 and RCHB2 (rear board of CHUB).

Clock signals connect with UIMC on the switching shelf via RCKG1 and RCKG2 (rear board of CLKG).

Processing of signals inside the shelf

i. User data

The switching shelf is a high-speed switching backplane. All network processing modules judge the route forward of the physical interface data.

The data is sent to PSN through the high-speed switching connection of the backplane for switching.

The switched data is received from PSN for processing.

At last, the data is sent from the physical interface.

ii. Control data

UIMC switching uses the Ethernet bus as the internal control bus of the subsystem, connecting all modules in the subsystem, distributing and collecting route information, maintaining and managing system configurations, and passing the protocol and signaling data of the high layer.

The backplane of switching shelf is BPSN.

Figure 36 shows the rear view of BPSN backplane.

If all digits of S2 are ‘ON’: the binary output is ‘0000’;

If the left two digits of S3 are ‘OFF’ and the rest are ‘ON’: the binary output is ‘11’.

It shows that S1 output is 0, S2 output is 0, and S3 output is 3. The actual Rack No. and Shelf No. are 1 plus the output. Thus the configuration indicates that the BPSN shelf is in: Shelf 4, Rack 1, Office 0.

Note: Backplanes BPSN, BCTC and BUSN have DIP switches. The ON/OFF setting method is similar in all the backplanes.

OFF: Indicates ‘1’ if DIP switch is down

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.

Clock Generator (CLKG)

CLKG is the clock generator board of ZXG10 iBSC system. Active and standby CLKG boards locks to the same reference to implement smooth switchover.

Functions of CLKG board are as follows:

Provides system clock and external synchronization. It extracts clock reference through A interface and gives multiple timing reference signals to the interface units after intra-board synchronization.

Supports background or manual selection of reference sources, including BITS, network (8 kHz), GPS, and local (level 2 or 3). Manual switchover can be screened by software.

Adopts loose-coupling phase-locked system, working in 4 modes: CATCH, TRACE, HOLD, and FREE.

Outputs Level-3 clock.

Performs clock loss alarming and deterioration judgment for inputted reference.

Supports active/standby switchover.

Figure 50 shows the working principle of CLKG.

Functions

Principle



It manages the board, communicates with the system control unit, implements the core clock control algorithm, outputs the clock signals, and selects the reference according to the data that the phase detection and phase locking unit provide.

Reference selection unit

It selects the suitable reference clock from several input clock under the control of the main processing unit. The clock reference can be from 8 KHz frame synchronization signal of DTB or APBE clock reference, 2 MHz/2 Mbits of Building Integrated Timing System (BITS).

Voltage controlled oscillator unit

The constant temperature crystal oscillator that meets level-3 clock standard provides the clock source with high precision.

Phase detection and phase lock unit

It compares the adjustment clock signal and input reference phase and provides the quantized data for the main processing unit, to control the voltage controlled oscillator unit. The phase lock system adopts the loose coupler phase lock principle.

Active/Standby switchover unit

It implements the active/standby switchover (the compact of the switching on the clock should be within the allowed range). The active/standby CLKG is locked in the same reference, for the smooth switchover.


Select one channel of input reference clock to lock the phase and output 16 M and phase head signals that meets the requirements of scheduling. After the balanced dived, the data is distributed to UIMU.

Perform the pulse expansion on the received PP2S and 16 CHIP signal, and then distribute the new PP2S to UIMU.

Functions

Principle



F I G U R E 62 - W O R K I N G P R I N C I P L E O F PWRD

By structure, PWRD falls into the following parts: One PDM, one PWRD, one PWRDB and four fan group control modules.

PDM implements filter, lightning protection and isolation on 2-channel -48 V, sends it to the busbar to supply shelves, samples and sends the samples to PWRD for over-/under-voltage monitoring before the 2-channel power supply convergence.

PWRD detects the 2-channel -48 V over-/under-voltage, speed of 24 fans, ambient temperature, ambient humidity, smoke alarm, infrared alarm, cabinet, and equipment room door control.

PDM and PWRD form a power distribution plug-in box.

2 × 3 fan group and the fan group control module form a fan plug-in box.

Fan plug-in box takes -48 V from the busbar and sends fan monitoring signals to PWRD.

PWRDB provides external monitoring signal interface for PWRD, accessing the system monitoring signals.

Figure 63 shows the diagram of PWRD board panel.

Chapter 4 –Boards


PWRD has two DIP switches:

S2

S3

S2 switch is used to set the address for 485 communications, with ON being 0 and OFF being 1.

S3 configuration switch is used to set working mode, with ON being 0 and OFF being 1. ON is labeled on the switch. 485 addresses are 0, and value of configuration switch is 0100, by default.

There is a 2 × 5 feet pin on PWRD, serving as a connection jumper X8 for 485 signals.

When ZXG10 iBSC system uses multiple cabinets, it is necessary to set the working mode for 485 bus of PWRD according to rack positions. Resistance terminals are necessary if PWRD is at the end of the 485 bus. 485 signals need to be transmitted to output if PWRD is at the middle of the bus.

Figure 64 shows the default jumper settings.

F I G U R E 64 – J U M P E R S E T T I N G S

Specific jumper connections are as follows:

For 485 bus end node: connect pins 1 to 2 and 9 to 10.

For 485 bus middle node, 485 single transmission: connect pins 3 to 4 and 7 to 8.

Wireless Modem 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


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.
