TDC Provides Superior Voice Quality and Landline Security on New Residential Broadband Telephony Service with Cisco IP Next Generation Network

Cisco Voice Over Broadband Solution Helps TDC to
Offer High-Quality Broadband Telephony to Cable and DSL Customers

Cisco Systems(R) (NASDAQ:CSCO) announced today that Denmark's
largest communications solutions provider, TDC, is delivering new
high-quality broadband telephony services to residential customers
with Digital Subscriber Line (DSL) and cable access using a voice over
broadband solution on its Cisco(R) IP Next Generation Network (IP
NGN).
TDC launched its broadband telephony service across Denmark in
February 2006, offering flat-rate national landline calls for
residential customers. The Cisco IP NGN voice over broadband solution
supports both IP Multimedia Subsystem (IMS)-compliant Session
Initiation Protocol (SIP) and PacketCable standards making it possible
for TDC to address broadband customers across multiple access networks
with a uniform set of voice services. The TDC network will also
support the introduction of advanced real-time communications features
and applications.
"TDC's objective for broadband telephony is to offer our customers
added value and choice," said Gert Rieder, executive vice president,
TDC Residential. "It was important to find a solution that provided
voice quality and security that are comparable with existing landline
telephony, which we can enhance with new features."
The Cisco solution includes Cisco BTS 10200 and PGW 2200 Series
softswitches and Cisco AS5000 Series VoIP gateways which are installed
in TDC's nationwide network to help TDC to deliver high-quality
broadband telephony. The Cisco BTS and PGW softswitches control the
calls and help ensure transmission quality, and the Cisco VoIP
gateways provide high quality connectivity between the broadband
network and the public telephone network, in line with the IMS
standard. This results in a highly-secure VoIP infrastructure that
works to prevent the tapping or hacking of calls.
TDC is installing residential gateways from Linksys, a division of
Cisco, for ADSL customers. These are located at the customer's home
between the DSL broadband modem and existing telephones. For cable
customers, TDC is using the WebSTAR(TM) DPX2203(TM) Cable Modem from
Scientific Atlanta, a Cisco Company, which features an embedded media
terminal adapter providing two lines of voice service. These devices
help to ensure that bandwidth is always available for phone calls on
the broadband line even if members of the household are surfing the
Internet or downloading media files such as music and video.
"The successful launch of TDC's broadband telephony service is the
result of close collaboration between Cisco and TDC over several years
and we look forward to helping TDC to continue delivering a
high-quality experience to their customers," said Geraint Anderson,
vice president of Service Provider Wireline for European Markets,
Cisco Systems.
