- Solution Being Deployed by European Mobile Operator Supports Rich
Communication Suite Initiative

Tektronix Communications, a leading worldwide provider of communications
test and Network Intelligence solutions, announced today that the explosion
of multimedia services and convergence of fixed and mobile broadband networks
is driving increased IMS deployment and propelling growth for end-to-end
monitoring and assurance solutions from Tektronix Communications. The
company's IMS Service Assurance solution provides a complete end-to-end view,
irrespective of the technology domains a call may traverse as it crosses the
network.

IMS networks provide a single platform for a wide variety of services,
from basic voice, video and messaging to new, highly-sophisticated services
such as video conferencing, telepresence and rich communications. IMS, the
common source for these services, will require multiple entities and
functions that must be managed proactively and in real-time. Subscribers to
IMS services are forecast to reach 160 million by the end of 2011, up 43
percent from 2010, according to Infonetics Research.

Tektronix Communications' IMS solution helps service providers assure
voice and multimedia in an IP network or in a network that is transitioning
to IP, by providing an optimized media troubleshooting workflow. Featuring a
rich set of quality of service (QoS) sources and integrated media capture,
analysis, playback and export, this intuitive, optimized tool provides rapid
and effective root cause analysis for VoIP and multimedia over IP QoS issues.

"We've seen more service providers developing their new generation of
services with IMS. These services span LTE, NGN and legacy SS7 technologies,
and involve increasingly complex signaling setup and interworking," said Mark
Driedger, Vice President, Network Management, Tektronix Communications. "Our
IMS Service Assurance solution offers a highly-flexible view on actual IMS
service performance with full correlation of signaling and media, regardless
of the underlying network, to ultimately help ensure customer quality of
experience and subscriber retention."

Tektronix Communications' deep experience in IMS recently led to its
solution being deployed to monitor an IMS network that will support a major
Rich Communication Suite (RCS) initiative for a pan-European mobile operator
group. The RCS project is a collaborative effort coordinated by the GSMA, now
supported by nearly 100 operators, vendors and other telecommunication
companies, that facilitates the introduction of commercial, rich IMS
communication services for mobile as well as fixed networks.
