Project TA1-T10
Project Data – Project ending date: 1995
TA1-T10 main goal
• The goal was to define new optimised developing plans
for Polish telecommunications network.
Project BBL
BBL Project Data – Project ending date: June 1999
BBL main goal
• Define and test in three field trials a concept for a cost
effective broadband access network which will allow fibre
to migrate gracefully into the local loop as bandwidth
demand increases.
• The concept was build on the existing coax and copper
twisted pair infrastructure for the last drop when
economical feasible.
Project BBL
BBL main goal
• The project was devote a major effort to define and build
an optical access network with the following
characteristics: cost effective, compact, low power
consumption, modular extendible bandwidth up to 1 Gbit/s
(155Mbit/s+16x52Mbit/s) downstream and 576Mbit/s
(16x10Mbit/s + 8x52Mbit/s), flexibility in bandwidth
allocation, high transmission quality and robustness
towards outside plant performance. The network was
provide transparency for both existing narrowband
services and future ATM based broadband services.
Project BBL
BBL main goal
• Field trial with real users and a range of broadband
services were use to evaluate the network concept.
System performance were measure over an operational
period of one year.
• The Life Cycle Cost (LCC) estimations were guide the
technical work in the project and were applied to evaluate
competitiveness between different drop solutions (copper
twisted pair, coax, fibre, radio). LCC studies were
supported by traffic studies leading to estimation of
bandwidth demand and influence on the bandwidth
demand by optimal location of ATM switching in the
network.
Project BTI
BTI Project Data – Project ending date: December 1999
BTI main goal
• In order to meet requirements for improved quality of
Internet Services the project has developed and
demonstrated a concept for improved Quality of Services
(QoS) based on integration of IP and ATM. The focus of
the work has been on an ATM based Passive Optical
Network (APON).
Project BTI
BTI main goal
• The network concept is supporting unicast and multicast
with well-defined QoS control in terms of controlled load and guaranteed service. The QoS controlled network is
based on IPv6, RSVP, PIM, NHRP and ATM with point to
point and point to multipoint SVCs. Each of these
technologies have a role in increasing network
performance, lower cost and providing a well defined
network service quality for the end user.
Project BTI
BTI main goal
• The technical performance of the network has been
measured in order to evaluate the viability of the concept.
• A program of structured usability testing has been
performed to evaluate the user perception of the QoS
control and the user interface. For this purpose user
applications for distance learning were enhanced with
QoS network control via RSVP and ATM signalling.
• Students and teachers at universities and schools in
Denmark, Poland, and Portugal have been connected to a
trial network.
IST Project LION
• LION main goal
„The goal is to design and test a resilient and managed
transport network realised by an Optical Transport
Network (OTN) carrying different clients (e.g. SDH, ATM,
IP-based) with interworking and interconnection between
layer networks and domains. ”
