Capacity Enough for all Media Services
In addition to providing connection to the Internet, the
Kaustinen network enables its users to watch television via
broadband and make low-cost IP calls.The system currently
includes 600 telephones.
"Calls are made by private households, companies and
municipalities.The telephones work in the same way as
traditional fixed line phones, with the marked difference that
calls made within the regional network are free, " says
Karvonen.
Network customers can also watch Finnish digital TV channels
through the network.TV pictures are transmitted on the
network by multicasting.The network customers have also
produced their own local TV programmes and broadcasts,
further boosting the community nature of the network.
The Allied Telesis system enables the provision of efficient data
transfer and diverse services to the network customers. In the
future, high-definition television images will also be
transmittable via the same network.
"Tests have been successfully run on the Kaustinen
subregion network at full 1080i resolution.The
highest resolution HDTV images were
transmitted over the optical fiber network
in the same way as traditional data, "
Karvonen continues.

The Triple Play network is even more diverse than the name
would suggest: multicasting technology opens up a versatile
range of video-conferencing and distance learning possibilities.
The network is also used for remote monitoring and
transmitting surveillance camera images.
"For example, remote monitoring of the biogas plant in the
village of Meriläinen has been implemented via optical cable
and the fast connection can also be used for the remote
monitoring of pig-houses.This saves a great deal of work
where travelling distances are considerable, " says Kari
Karvonen.
According to village representative and key organiser of the
network Iiris Jurvansuu, the Kaustinen subregional network has
enabled centralised provision of administrative services to
local residents and enabled teleworking via the network.
"The subregion's residents are increasingly able to access the
services they need through the network.The network also
means people from outside the subregion can work here
from their second home or summer cottage. "
Jurvansuu also emphasises the effects on the
community of the far-reaching project.
"The single most visible impact has probably
been the fact that young people are heavily
involved in building and using the village
networks.The data network has
become a community project and
is also establishing links and
contacts around the world. "
