Founded in 1895, TSC is the incumbent provider
Columbus
Columbus
in the cities of Wapakoneta and Cridersville and
Dayton
surrounding areas, and is a CLEC in the cities
Cincinnati
of St. Marys and Lima. Facing competition from
providers such as Time Warner Cable, Embarq, and
Verizon, TSC has spent the past decade upgrading parts of
its ILEC plant with HFC cable while rolling out fiber to the
home (FTTH) in its CLEC territories.
TSC is typical of many second tier Independent Operating Companies
(IOC’s), where community needs are as important as competitive service
requirements. TSC brands itself as “Telecommunications. Service.
Community.” TSC saw increased demand within the community for
higher quality digital services, including television, along with the need
for more programming and information. For the past two years, TSC
has been delivering triple play voice, video and data services over FTTH
networks in Lima and St. Marys.
However, 35 percent of its ILEC customers are on copper connections,
and the HFC network that reached the rest couldn’t handle a full suite of
advanced triple play services. The company risked losing these customers
if it couldn’t find a way to cost-effectively deliver the same services to
them. “Once we had begun offering triple play services (voice, data, and
TV with pay-per-view) in Lima and St. Marys, a number of our customers
asked for the same bundle of services in other areas, but we couldn’t
provide it,” says Jason Neumeier, CTO of TSC. “We were looking for a
solution that could provide voice, video, and data over copper.”

The company’s strategy was to expand its copper network to all of its
HFC service areas as a more cost-effective way to upgrade for triple
play services. It plans to continue using HFC to deliver analog video
while using DSL to deliver IPTV, data, and voice services. “Our copper
network is in excellent shape,” says Lonnie Pedersen, President of TSC.
“A lot of it is only 10 or 15 years old, and we wanted to leverage that

investment to deliver the next generation of entertainment services to
our customers.”
TSC evaluated three different vendors for its triple play platform in June,
2005. Platforms had to support ADSL2+ data and POTS voice services
along with reliable, high-quality video distribution. Zhone’s MALC
product won the competition for several reasons:
n
Flexible line bay replacement options in a chassis-based system
n
1+1 architecture redundancy to ensure continuous service
n
Higher POTS line density
n
A standards-based protection architecture (RPR)
n
Multicast video stream accountability for bandwidth efficiency
and ease of management
n
Having a complete end to end system that included subscriber
termination equipment optimized for IPTV service.
n
Better ADSL2+ performance
“We had some legacy solutions in our ILEC area, and the Zhone equipment gave us the opportunity to replace older switches, because its DSL/
POTS cards do voice switching,” says Neumeier. “Zhone also had some
attractive security features, and we liked the modular chassis, because
that let us deliver a mix of services based on business or residential
customer needs.”
With its 21-slot chassis, the MALC 723 can deliver ADSL2+, IPTV, POTS
and VoIP services. Beginning early in 2006, TSC began deploying MALC
The MALC 719 and 723 can deliver ADSL2+,
IPTV, POTS and VoIP services
systems in rural portions of its ILEC network, and is targeting 80 percent
coverage of its ILEC area’s remote terminals and central offices by the
end of the year. “With the MALC, we can offer the whole triple play
bundle to any customer,” says Neumeier. By replacing legacy gear with
the MALC, TSC has also been able to double the speed of its ADSL2+
offering from 2.5Mbps to 5Mbps.

TSC’s IPTV infrastructure includes Amino set-top boxes and Terayon
servers and head-end equipment. Although TSC had already committed
to using another vendor’s IP voice gateways for its business VoIP services
prior to the Zhone deployment, Neumeier says that the MALC helps keep
costs lower because it enables all-IP transport between remote terminals
and the central office.
Zhone’s MALC has enabled TSC to leverage its legacy copper plant,
deliver a full range of triple play and business services over the new
and existing copper network, replace expensive legacy service platforms,

way to upgrade our

and roll out services on an as-ordered basis with a flexible, chassisbased system. By switching to the MALC’s all-IP architecture, TSC has
also consolidated its service platforms to reduce operations costs and
improve reliability.
Summary comments
An increasing number of IOC’s are expanding their business base
through CLEC overbuilds in neighboring markets. Likewise, operators today find it economically practical to use FTTP in new builds
and, if the copper plant is good, DSL in existing neighborhoods. MALC
offers and ideal fit by supporting both fiber/PON and DSL from a
single chassis, eliminating the need to purchase and maintain multiple
systems based upon media choices. Yet the service needs (voice, data
and video) is the same for customers served on fiber as it is for those
on copper. Therefore, the access platform capabilities must support
universal broadband services across any type of media. TSC exemplifies
a practical application of this approach.
