Columbus International Inc. Selects Calix E7 to Deliver Advanced Fiber Services 
in the Caribbean 
Homes and Businesses in Three Countries Experiencing the Power of
GPON and Gigabit Ethernet Technologies 
ATLANTA, GA -- (Marketwired) -- 10/21/13 --  Calix, Inc. (NYSE: CALX)
today announced that Columbus International Inc. (Columbus), a
leading telecommunications provider in the Caribbean and Latin
America regions, has selected the Calix E7 Ethernet Service Access
Platforms (ESAPs) and 836GE Residential Services Gateways (RSGs) to
expand its fiber initiatives in the region. These gigabit services
capable networks will leverage GPON and point-to-point gigabit
Ethernet technologies in greenfield and overbuild environments to
deliver digital voice, managed IP video, and advanced data services
to residences and businesses. Fiber-based services utilizing the E7-2
modular ESAP and E7-20 multi-terabit ESAP have already been deployed
on the islands of Barbados, Jamaica, and Trinidad and Tobago to
service Columbus' residential customers under its Flow brand and
business customers under the brand Columbus Business Solutions. The
deployment will expand to other countries that Columbus serves as
demand for advanced broadband services grows. 
According to Darren Richer, chief technology officer at Columbus,
"Our goal is to deliver superior broadband services to our
residential and business subscribers over the most efficient
infrastructure possible. In situations where we are building out new
plant or need to upgrade existing infrastructure, we see IP services
over fiber as the optimal path. The Calix E7s snap into our existing
back-office infrastructure, allowing us to easily complement our
networks with advanced fiber services efficiently and effectively."  
Columbus has been updating and expanding its existing infrastructure
and network in Barbados with fiber to deliver more
bandwidth-intensive services. In addition to the flexibility of the
Calix E7s, the Calix Management System (CMS) easily interoperates
with existing back-office systems, delivering a number of internal
efficiencies in subscriber activation and provisioning.  
"Cable operators are integrating fiber into their networks globally
to support the advanced business and residential applications of the
future," said John Colvin, senior vice president of North American
sales and marketing at Calix. "In the Caribbean, many of the
countries have social initiatives that seek to drive global
competitiveness through state-of-the-art broadband offerings.
Columbus has become a key enabler for these aspirations for the
entire region, and is betting that investment in fiber provides the
company a key advantage in meeting the emerging broadband
requirements and expectations of the countries that it serves."
