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.

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:

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.

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.

The packet domain packet switching shelf implements data interworking, including timing, signaling, voice service and data
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.
The rear view of BPSN backplane is as shown in Figure 51.

ETSN has 128 K switching capacity supporting eight resourceshelves while STSN has 256 K switching capacity supporting 16resource shelves. ETSN is used when there are less than eight
resource shelves, STSN is used when the number of resourceshelves is more than eight or could become more than eight infuture capacity expansions. Each resource shelf provides 16 Ktime slot switching with circuit switching shelf implementing fullT network switching. TFI board supports 64 K time slot switchingand could connect to four resource shelves at present. SBCXboard could be configured in circuit switching shelf or resourceshelf when there is no separate control shelf.

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.

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.
