Chapter 1 - Cabinet


DTB supports E1 cables

The interface between iTC and iBSC is called Ater interface.

Transcoder resource assignment signaling, Ater interface circuits

management signaling, A-interface circuits managementsignaling, and voice data are transmitted on Ater interface.

Application layer protocol for signaling is called Ater protocol,which is based on SCCP/MTP layers of No.7 Signaling.

Voice data is in GSM FR/EFR/HR/AMR TRAU frames.

iTC Ater interface supports E1 and STM1 connections with MSC.

The foreground/background interface is the interface connectingZXG10 iTC background NM and iTC foreground device. Thebackground NM software cannot manage and configure the iTCforeground board without this interface. Foregroundcommunicates with the background through TCP/IP protocol.

The background computer, having ZXG10 iTC NM software, isconnected with the OMP and SBCX board of iTC via 100 MbpsFast Ethernet interface.

Plug-in Boxes

This chapter describes the structure, functions, and panel

descriptions of ZXG10 iTC plug-in boxes.


Power distribution plug-in box is located in the upper part of thecabinet. It provides power to all components of the cabinet.

Functions of power distribution plug-in box are as follows:

Provides power to all shelves within a cabinet

Implements power backup by automatically switching over

two external power supplies

Implements power indication, environment monitoring, andinternal fan plug-in box monitoring through PWRD andPWRDB

Shelves

This chapter describes the structure, configurations, functions

and principles, interfaces, DIP switches and jumpers of ZXG10iTC shelves.

Overview

The shelf combines various boards through the backplane to

form an independent unit, and provides good runningenvironment for the boards.

ZXG10 iTC system has four types of shelves:

Control shelf

Resource shelf

Packet switching shelf

Circuit switching shelf

Table 13 explains the types and functions of these shelves:

Shelf Configurations

Figure 34 shows the shelf configurations of ZXG10 iTC cabinet.

F I G URE 34 ZXG10 ITC SH E L F CO NF I G URAT I O NS

Resource shelf should be configured in the second and third

shelves of iTC cabinet and control shelf is configured in thesecond shelf of the third cabinet if needed. For one or twocabinet iTC configuration, control shelfs boards are distributedin other shelves because of the lack of enough space to have aseparate shelf.

Packet switching shelf and circuit switching shelf should be

configured in the fourth and first shelves respectively.

Backplane

Backplane is an important part of a shelf. Circuit boards in a

shelf connect through printed lines on the backplane. It reducesthe cable routing on the back of backplane and improvesreliability of the whole system.

Figure 35 shows the backplane structure.

Inter-shelf signal interaction

iTC supports to configure a pair of CLKG boards. CLKG is

a part of the control shelf but is configured on the circuitswitching shelf in case the iTC is one or two cabinet. The

system clock is distributed to switching shelves andresource shelves via the cable.

OMP and SBCX boards are connected with iTC NetworkManagement System (iTCM) through Hub, isolating theinternal and external network segment. The iTCM couldreside on the SBCX board or on an external server.

CHUB is the center where the control flows of theswitching shelf, the resource shelf, and the control shelfgather.

Principle


44/151



Intra-shelf signal processing

BCTC backplane bears signaling processing board and MSmodules. It gathers and processes the control plane dataforming a distributed processing platform in the multi-

shelf system.

UIMC is the signaling switching center of the control shelf,implementing the information switching between modules.

OMP board is responsible for the global processing andcontrols O&M of the whole system (including O&M agent).

OMP board is the core of ZXG10 iTCM. It directly orindirectly monitors and manages the boards. OMP boarduses Ethernet and RS485 to configure and manage theboards.

SBCX is connected with iTCM via Hub. It saves some files

needed by OMP, and organizes these files according tothe form required by iTCM.

CMP board is connected with the switching unit of controlplane, implementing all the protocol processing on control

plane.

The backplane of control shelf is BCTC. Figure 39 shows the rearview of BCTC backplane.

service. It provides the QoS function for different subscribersaccording to service requirements.

The packet domain packet switching shelf adopts a high-speedswitching backplane. Network processing boards first performphysical interface data routing transfer; then implement data

switching by sending the data to the switching network via thehigh-speed switching connection of the backplane; they alsoreceive data from the switching network and send the data via

the physical interface after processing.

Boards

This chapter describes the functions and structure of ZXG10 iTC

boards.

Overview

According to the hardware assembly relation, boards can beclassified as front board and rear board.

Front board has a front panel. Indicators on the front panelindicate the board status. Front board can be inserted in theslots.

Rear board consists of the external interfaces and debugginginterfaces. These interfaces are used to interconnect shelvesof same cabinet or different cabinets. The rear board and thefront board work together. For some active/standby frontboard, it is necessary to configure two kinds of rear boards.

Front board and rear board are installed in the slots on thebackplane.

Front board and rear board form a complete metal shieldinside the shelf, reducing the external electromagneticradiation of the system and enhancing the anti-interferencecapability.

Figure 59 shows the board assembly relation.

the control bus, to configure the switching chipset. It hasexternal RS232 and RS485 serial ports for debugging.

Logic unit

It implements all logic processing functions of the board.

Ethernet switching unit

It performs Ethernet switching, implementing the

gathering on the control plane.

Board data flow direction

The data of the control plane from all shelves is sent toEthernet switching unit on CHUB.

The data is sent to UIMC on the control shelf via GE

interface, and then is distributed to CMP for processing

and vice versa.

Figure 61 shows the panel diagrams of CHUB board, RCHB1 andRCHB2. RCHB1 and RCHB2 are the rear boards of CHUB.

Clock Generator (CLKG)

CLKG is the clock generator board of ZXG10 iTC. Active and

standby CLKG boards locks to the same reference to implementsmooth switchover.

Functions of CLKG board are as follows:

Provides system clock and external synchronization. It

extracts clock reference through A interface and givesmultiple timing reference signals to the interface units afterintra-board synchronization.

Supports background or manual selection of referencesources, including BITS, network (8 kHz), GPS, and local

(level 3). Manual switchover can be screened by software.

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

Outputs Level-3 clock.

Performs clock loss alarming and deterioration judgment forinput reference.

Supports active/standby switchover.

Figure 62 shows the internal structure of CLKG.

CLKG consists of the following units:

i. CPU small system unit

It is the MS unit of the board, controlling and processingthe signals.

ii. Circuit clock unit

It provides the working clock to other modules; extractsthe clock from the line and sends to the backplane.

iii. Power supply unit

It provides the power supply signals for other parts insidethe board.

iv. GPS unit (ICMG has it while CLKG does not use GPS unit)

It comprises of GPS receiver and phase locked loop. It isindependent system. GPS unit is not used in iTC system.


Select one channel of input reference clock to lock thephase and output 16 MHz and phase head signals that

meets the requirements of scheduling. After the balanceddivide, the clocks are distributed to UIMT/UIMC.

DTB consists of the following five units.

Main processing unit

It manages the board and controls the internalconnection.

Interface unit

It connects with the circuit switching unit, providingE1/T1 and HW interfaces.

Circuit switching unit

It switches over the circuit HW of the interface unit.

Logic processing unit

It implements the logic switchover inside the board andthe adaptation function.

Clock processing unit

It receives the clock sent from backplane and provides it

to the board after frequency division and time scheduling.


E1/T1 data from the line side passes the interface unitprocessing link layer and is sent to the circuit switching unitfor switching. Then via the interface unit, the data is sent toUIMT inside the board and vice versa.

RDTB is the rear board of DTB.
