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.
