Carrier-class component

Soft switch: SoftX3000SoftX3000 offers an integrated solution for both fixed

and mobile network which is deployed in the control

layer of NGN. Adopting DOPRA on Carrier-class platform

ensures the 6H features of the euipment - high

availability, high reliability, high realtime, high

scalability, high load balance and high compliance to

open system. At maximum, SofX3000 supports up to

2 million subscribers, with the processing capability up

to16M BHCA.

Trunk media gateway TMG8010Locating at the edge access layer, TMG8010 acts as

media gateway to enable inter-working between PSTN

and NGN network with outstanding QoS guarantee.

TMG8010 implements the coding/decoding between

the voice traffic flow carried in IP packet network and

Universal media gateway UMG8900UMG8900 supports both narrowband and packet

switching functions with multiple access interfaces.

The packet switching provides IP interface to imple-

ment service traffic process and conversion between

IP/TDM network, which implements efficiently the in-

ter-working between different networks.

As a large capacity Universal Media Gateway (UMG)

in NGN, it performs the functions of subscriber access,

large-scale TMG, NGN-enabled switch and mobile

network gateway as well.

the PSTN circuit voice, packing/unpacking and delay

jitter removal. Its built-in signaling gateway helps to

implement the coding/decoding of SS7 and voice flow

simultaneously.

Signaling gateway SG7000Besides built-in signaling function in TMG, SG7000 as

independent signaling gateway is also available to

fulfill the inter-working between PSTN network and

NGN so as to cooperate with the softswitch and other

IP-based database equipment (e.g. IP-HLR, IP-SCP

and IP-SMSC). It provides up to 5120 64K links and

built-in STP function.

Multimedia resources server: MRS6000Under the control of SoftX3000, MRS6000 provides

medium resource to packet network. Unlike the tradi-

tional packet peripherals (IP) based on circuit

technology, MRS6000 is directly based on packet

technology and eliminates the coding/decoding con-

version of from TDM to IP, resulting in high quality

medium flow on IP.

Secure and reliable network structureU-SYS provides powerful AAA (Authentication, Authorization and Accounting) for both card users and fixed-line

users, together with security measures such as address anti-fraud, anti-attack for network key equipment (such

as DHCP Server, Radius Server, etc. ), monitor and control of user bandwidth and traffic volume, etc.

NGN-enabled Switch application

Current PSTN is narrow-band TDM circuit-switch network. In order to evolve to NGN and also take into account

the evolution requirement of current network, U-SYS solution (SoftX3000+UMG8900) implements the traditional

switching functions based on NGN technology. SoftX3000 implements the soft switch function and UMG8900

implements the user access and switch function.

Through this way it can reconstruct the PSTN step by step on the basis of being compatible with the current TDM

interface to implement the smooth evolution to NGN.
