 Introduction

 Working Principle

 Software Architecture

 Hardware Architecture

 System Features

 System Functions

Introduction

ZXMSG 5200 Multiplex Service Gateway is one of the major Next

Generation Network (NGN) oriented products recently developed

by ZTE. NGN combines the public switched telephone network

(PSTN) and Integrated Services Digital Network (ISDN), creating

a single multi-service network.

ZXMSG 5200 is a type of integrated media access gateway but

also provides narrowband and broadband services. It adds a

Voice over Internet Protocol (VoIP) module to the previous

generation systems. ZXMSG 5200 adopts standard application

layer and transport layer protocols to convert and handle access

streams. At the same time, it is compatible with existing

network devices. It provides many user side and network side

interfaces for different network environments, which effectively

meets the integrated services access requirements. It also

provides high access multimedia services and Application

Programming Interface (API) generated services.

ZXMSG 5200 uses various technologies as listed below:

 Ethernet

 Asymmetric digital subscriber line (ADSL)

 ADSL2+

 Single pair high digital subscriber line (SHDSL)

 Multicast

 Ethernet passive optical networks (EPON)

 ISDN

 PSTN

ZXMSG 5200 can fulfill the following subscriber requirements:

 High speed internet access for residential and office

subscribers.

 High quality services, such as teleconference and fax for

commercial subscribers.

 Operation and maintenance demands of broadband

subscribers.

 Subscriber security administration and modem management.

 NGN access gateway (AG) requirements and for upgrade

MSAN equipment into AG at low costs.

Working Principle

ZXMSG 5200 core technology is ‘TDM + IP’ and supports two

types of switching networks:

 Circuit-switching

 Ethernet-switching

Principle

Chapter 1 Introduction

Confidential and Proprietary Information of ZTE CORPORATION 3

ZXMSG 5200 working principle is as follows:

 Narrowband service signals enter the TDM switching module

of main control card (i.e. ICS/EICS/GIS).

 TDM switch performs circuit-switching on the voice signals

and send them to voice compression module.

 MPR voice compression function converts voice traffic into IP

packets and send them to Ethernet switching module.

 Ethernet switching chip switches the IP packets and send

them to CNIC for network address translation.

 After network address translation, IP packets enter the IP

network through an uplink interface after Ethernet switching.

 Broadband data enters ICS Ethernet switching chip and

directly goes to IP network through an uplink interface.

Software Architecture

The software system provides following functions.

 Resource management

 Software modules interfaces

 Database configuration implementation

 Operation and management (O&M)

System Features

ZXMSG 5200 system features are as follows:

ZXMSG 5200 completely meets public telecommunication and

private networks requirements. ZXMSG 5200 also provides

broadband subscriber interfaces. These interfaces are used for

broadband service configuration according to subscribers'

requirements.

The system size is smaller. Network architecture and

configuration are simple and suitable for local network

optimization.

The system provides mutual backup for power supplies and

active/standby backup for ICS cards. ZXMSG 5200 has two ICS

cards at each layer of subscriber shelf and only one is in the

active mode at a time. The one which is in the active status is

called the active, while the other one is called the standby. In

case of failure of the active card, the standby card takes over

the system control. This process is active/standby switching,

which keeps the whole system running from being affected and

greatly improves the system reliability and stability.

The system capabilities are as follows:

 Ethernet convergence, switching, and Ethernet L2 protocol

processing

 Interfaces for broadband services such as IP/xDSL

 PSTN/ISDN subscriber line test and DSL subscriber line test

(in coordination with an external DSL subscriber line tester)

The whole system is based on a uniform Ethernet switching

platform. It implements switching of three data flows:

 Intra-module control information

 H.248 protocol

 RTP data

This Ethernet unit is totally private, not connected to any

external Ethernet, and outgoing data flows pass through the

CNIC egress uniformly to ensure security.

MPR/MPRB card converts voice signals into IP packets.

ZXMSG 5200 supports 100 Mbps (FE) and 1000 Mbps (GE)

Ethernet interfaces at the IP network side, which are used as

egresses for narrowband media flow, H.248 protocol flow,

network signal flow and broadband data flow. These four data

flows can be flexibly configured on any uplink Ethernet port.

ZXMSG 5200 supports networking with multiple SoftSwitch.

When many SoftSwitches are in an active/standby relation, the

ZXMSG 5200 supports H.248 polling registration. When an active

SoftSwitch fails, the SoftSwitch will contact a standby SoftSwitch

automatically and accepts its control.

System Functions

In a NGN network with SoftSwitch, ZXMSG 5200 can take the

place of traditional access network in networking or to support

hybrid networking with the SoftSwitch in access networks.

ZXMSG 5200 provides following functions:

 The SoftSwitch to which ZXMSG 5200 is attached

implements voice compressing/decompressing facsimile and

more VoIP or IP FAX services under the control of

H.248/MGCP.

 Accesses common POTS-interface subscribers to provide

narrowband voice services. Gets analog POTS-interface

subscribers access to IP networks directly and implements

voice/fax conversion at the analog subscriber side and

voice/fax conversion at the IP network side.

 Accesses to broadband interfaces like ADSL/ADSL2+, VDSL,

SHDSL and Ethernet through different broadband protocols

to provide broadband services.

 Uses different narrowband, broadband and universal

protocols for providing different services.

 Provides end-to-end auto or semi-auto service configuration

functions at the network side which provides easy service

provisioning and adjustment.
