Tatara Systems Announces Partnership with Acme Packet for SIP-Based Femtocell Network Integration

ACTON, Mass., Apr 01, 2009 (BUSINESS WIRE) --
APKT | Quote | Chart | News | PowerRating -- Tatara Systems, the leader in SIP-based femtocell convergence, today
announced that it has partnered with Acme Packet(R) (NASDAQ: APKT), the
leader in session border control solutions, ensuring interoperability
between Tatara's Convergence Server and Acme Packet's multiservice
security gateway and session border controller (SBC) to deliver
SIP-based femtocell solutions for mobile operators. Tatara, Acme Packet
and AirWalk Communications will conduct live demonstrations of SIP-based
femtocell network integration at the CTIA Wireless 2009 event, April
1-3, 2009 at the Las Vegas Convention Center in Las Vegas, NV.

Femtocells have the potential to extend the reach of a mobile operator's
network into homes, and enterprises, positively impacting the customer
experience for millions of subscribers by enhancing coverage, and
providing capacity for bandwidth hungry applications. Tatara has staked
out an early leadership position in this market, as the first vendor to
deliver a SIP-based solution for femtocell network integration. As noted
by most industry analysts, IP-based femtocell deployment is the only
method that offloads the legacy mobile core infrastructure, thereby
providing the capacity needed for 3G service delivery and enabling
operators to recognize substantial cost savings through OPEX and CAPEX
optimization.

The Tatara Convergence Server (TCS) solution enables the interconnection
of femtocells and other advanced technology IP-based radio network
elements with the legacy macro network, providing the full mobile voice,
messaging and data experience in an IP environment supporting both VoIP
and IMS networks. The TCS capabilities include authentication of the
mobile subscribers, handoff between femtocells and the macro network,
emergency and supplementary services, as well as delivering new IP-based
applications to existing mobile handsets without modifying or disrupting
the macro network. The TCS is available in a CDMA or GSM/UMTS variant.

A demonstration of voice and data service delivery using SIP femtocells
will take place in the Acme Packet booth 5741. Within the
demonstration, Acme Packet's Net-Net(R) Security Gateway (SG) and Net-Net
Session Director (SD) will connect SIP-based femtocells to an IMS/NGN
data center. The femtocell, a CDMA AirWalk EdgePoint(TM), converts legacy
signaling and media to SIP and RTP for transport over broadband Internet
access connections. The Net-Net SG provides the femtocell security
gateway function for securely tunneling voice and data traffic across
the Internet using IPsec tunnels. Acme Packet's Net-Net SD session
border controller provides SIP session control, including
denial-of-service protection, admission control, protocol normalization
and other cost and quality controls. Acme Packet's SBC also routes
traffic to Tatara Systems' Tatara Convergence Server (TCS) which
provides voice, messaging and supplementary services as well as active
session handover to the macro cellular network. AirWalk Communications
(booth 8127) and Tatara Systems (booth 8951) will also be demonstrating
the CDMA SIP femtocell solution.

"As our partner ecosystem continues to grow, it helps to solidify our
leadership in the femtocell market," stated Marc Cremer, executive vice
president of operations for Tatara Systems. "With key industry players
embracing our SIP-based femtocell convergence solution, it serves to
increase the momentum towards the delivery of new IP-based applications
and the seamless migration to next-generation VoIP and IMS
architectures."

"SIP is the signaling protocol for next generation communications and
3GPP architectures," commented Seamus Hourihan, Acme Packet's vice
president of marketing and product management. "It is critical to work
with leading vendors, such as Tatara Systems, to deliver proven
interoperable solutions in order to successfully expedite the transition
to SIP for femtocells and all voice services."
