   Newport Networks Launches IMS/TISPAN Ready Session Border Control Products   


Newport Networks, the developer of carrier-class Session Border Controllers, has
today announced the launch of IMS/TISPAN-ready distributed signalling proxy and
media proxy functionality.

Large fixed and mobile operators are demanding converged networks based on IMS
and TISPAN network architectures that can scale to accommodate rapid growth in
Voice-over-IP (VOIP) services. Where existing session border controllers cannot
support these architectures without obsolescence or expensive upgrades, the
Newport Networks' 1460 offers industry-leading capacity and architectural
flexibility.

With IMS (IP Multimedia Subsystem) becoming increasingly important in strategic
network investment, Newport Networks' 1460 provides operators with the
flexibility required in deploying distributed session border control. Newport
has physically separated its SignallingProxyTM and MediaProxyTM allowing
MediaProxies to be controlled from 3rd party Softswitches and SignallingProxies
to be deployed standalone as 'SIP signalling firewalls'. This expanded
flexibility enables service providers to deploy the Newport Networks 1460 either
as a standard session border controller or as a separated Signalling Proxy and
Media Proxy that can evolve to IMS and TISPAN architectures without major
upgrades.

"IMS-readiness rounds out a Session Border Control solution needed to help Tier
1 and 2 service providers optimize network investment while growing their
subscriber base and geographic reach," says Joe McGarvey, a Senior Analyst at
Current Analysis. "The Newport Networks 1460's conformance with the IMS
specification and its distributed architecture, where signalling and media
processing is separate, provides carriers with a flexible and future-proof
security and session control platform."

John Everard, CEO of Newport Networks stated, "From an early stage Newport
Networks anticipated that to future proof the 1460 the Company would have to
build a separated signalling and media proxy into the architecture. This
approach positions Newport Networks as the best solution to safely migrate
carriers to IMS/TISPAN."

Newport Networks SignallingProxy and MediaProxy products are available now and
will be on show on Newport Networks' stand 426 at Fall VON in Boston.
