PHILADELPHIA -- February 15, 2013

Comcast Corporation, a global media and technology company, today announced it
is the first service provider in the world to achieve Carrier Ethernet 2.0 (CE
2.0) certification from the Metro Ethernet Forum (MEF) for E-Line and E-LAN
services. As more businesses shift from legacy telecom services to Ethernet,
the new CE 2.0 certifications are designed to deliver improved classes of
service, service manageability, and interoperability for delivery across
multiple networks.

“A milestone was reached this year when for the first time Carrier Ethernet
services share of bandwidth exceeded the sum total of all legacy telecom
services across the world, with Frost & Sullivan, Vertical Systems and
Infonetics predicting a near $48 billion services market by 2015. We are
therefore very pleased to see that Comcast has achieved the latest milestone
in our industry - becoming the first CE 2.0 Service Provider,” saidNan Chen,
president, MEF.

After extensive compliance testing by Iometrix, the MEF authorized
certification test lab, the MEF certified Comcast Business Class Ethernet
Private Line and Comcast Business Class Ethernet Virtual Private Line as CE
2.0 E-Line services and Comcast Business Class Ethernet Network Service as a
CE 2.0 E-LAN service. All of Comcast’s Ethernet services are delivered over
its next-generation, all-IP network that spans 39 states and the District of
Columbia and serves 20 of the top 25 U.S. markets. Completely diverse from any
telecom networks, Comcast’s network features a 100 Gbps backbone and
pervasive, fiber-rich reach into its markets with an expanded local footprint
through Ethernet over HFC. In addition, all of Comcast’s Ethernet network
equipment suppliers are CE 2.0 certified, ensuring consistent service delivery
across its nationwide footprint.

“From major healthcare groups to regional banks and organizations connecting
to data centers, a wide range of mid-market and enterprise customers are
turning to Comcast’s Ethernet services based on our extensive network reach
and service availability, true network diversity, and continued investment in
advanced network technologies,” said Mike Tighe, Executive Director of Data
Services at Comcast Business Services. “As the first service provider in the
world to offer CE 2.0 Ethernet services, this certification underscores our
commitment to being a technology and standards leader in the Ethernet
ecosystem to improve the quality, management and interoperability of Ethernet
services for our customers.”

In addition to being the first service provider in North America to offer CE
2.0 certified Ethernet services, Comcast Business Services was also the first
service provider to achieve all three of the previous CE 1.0 certifications
(MEF 9, 14 and 18). The company has also served on the MEF Board of Directors
since 2008, a seat currently held by Karen Schmidt, Executive Director of
Enterprise Product Marketing at Comcast Business Services.
