Slide1:  TA1-T10 New Optimisation Polish Telecom Network ACTS Project BBL AC038 (BroadBandLoop) ACTS Project BTI AC362 (Broadband Trial Integration) IST Project LION IST-1999-11387 (Layers Interworking in Optical Networks) presented by Janusz Maliszewski Telekomunikacja Polska S.A. Tel. (+48 22) 6571 377 Fax (+48 22) 6960 520 e-mail: Project TA1-T10:  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:  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:  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:  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:  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:  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:  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:  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.
