performs the traffic flow format processing and switching function. Act

as TG or as a switch in NGN.

User access module(UAM):

provides integrated access function for both narrowband and broadba

nd users act as AG.

Service Switching ModuleService Switching Module

Service switching module (SSM) of UMG8900 is consisted of 4 parts:

Main control frame

implements management and maintenance functions of the whole device and supports

service access and process simultaneously.

Service frame

provides service bearer process function.

Central switching frame

provides multi-frame cascading function when multi-frame cascading (≥3 frames).

Extended control frame

is configured when the device is in the maximum configuration. The extended frame

does not support access and process functions of bearer services, but provides

connection management and control function.

Introduction to BoardsIntroduction to Boards

The involved boards can be divided into seven categories according to

their functions:

Equipment and resource management unit (FOMU, FMPU , FCMF

and FCMB)

Service and protocol processing unit (FHRU and FSPF)

Switching and subtending unit (FNET, FTNU, TCLU, FFLU and

FBLU)

Interface board (FP1H, FG1O, FS2L, FS2E, FP4L, FE8T, FE32/FT32)

and backup interface board (FBGE, FBFE and FBAP)

Media resource processing board (FVPU, FECU)

Clock board and clock drive board (FCLK)

Subscriber access module (PV8, RSP, TSS, ASL, ESC, PWX and

HWC)



Software SystemSoftware System

The software system is divided into two parts by their different

functions and applications: host software and LMT system.

The host software is further divided into lower-layer base

software, service application software and maintenance and

management software.

UMG8900 is managed and maintained by the BAM module in

a hard disk built in the UMG8900 host.

Signaling Adaptation

Signaling Adaptation

The embedded SG of UMG8900 supports the adaptation of

multiple types of CCS and CAS.

common channel signaling (CCS) as SS7, DSS1 and V5 are

adapted based on SIGTRAN protocol.

channel associated signaling (CAS) such as R2 and No.5

and R2 multi-national adaptation are supported.

UMG8900 achieves R2 adaptation mainly by means of H.248

extended packets.

UMG8900 serves as TG or AG in NGN or as the traditional PSTN

switch and the next-generation switch:

1.In NGN, UMG8900 is applied in the gateway exchange and toll exchange as

large-capacity TG.

2.UMG8900 can provide next-generation TDM switch application.

3.UMG8900 can act as tandem exchange/toll office/gateway exchange/C5

networking application of PSTN .

4.Provides AG function of large capacity via RSP/PV8 user frame of UMG8900

accesses user directly.
