Broadband Interactive Services on Integrated Access

Objective

- To define an ATM-based system to establish access to private homes for new interactive broad band services utilising existing infrastructures where appropriate.
- To secure full extendibility of service provider equipment and portability of customer premises equipment by defining an open architecture based on internationally accepted standards.
- To verify technical feasibility of the system via a trial making use of an existing ATM core network as well as a CaTV access network infrastructure to residential homes.
- To verify the functional feasibility of the system by introducing services on the trial network.
The concept of an asynchronous transmission mode (ATM) based system to establish access to private homes for new interactive broad band services has been specified utilizing existing infrastructures where appropriate. Full extendibility of service provider equipment and portability of customer premises equipment has been secured by defining an open architecture based on internationally accepted standards. A trial making use of an existing ATM core network as well as a community antenna television (CATV) access network infrastructure to residential homes has been devised to verify the technical feasibility of the system. New modules have been developed. The technical approach consisted of a general system study, adaptations to existing systems, a field trial using ATM on CATV and an evaluation based on the trial experience. The general systems study covered an open concept for communications of interactive broadband services based on integrated access to private homes and using ATM from the service provision centre to the customers. The project focussed on the trial itself (verifying the CATV option) and the required adaptations to existing networks and subsystems. 10 terminals were connected to the network giving access to Home Cinema and Interactive News Service trials.
Technical Approach

The technical approach comprises a general system study, adaptations to existing systems, a field trial using ATM on CaTV and an evaluation based on the trial experience.

The general systems study covers an open concept for communication of interactive broadband services based on integrated access to private homes and using ATM from the service provision centre to the customers. Three access technologies are treated: CaTV, ADSL and PON. The provision of telephony over CaTV networks will also be assessed.

The project focuses on the trial itself (verifying the CaTV option) and the required adaptations to existing networks and subsystems. The trial will run for three months. It will exploit BATMAN, the Danish national ATM trial network and an existing CaTV network upgraded for upstream data transmission. This CaTV is operated by Jydsk Telefon. Ten terminals will be connected to the network giving access to Home Cinema and Interactive News Service trials..

The system will be demonstrated to persons representing CaTV user associations and consumers' council. Their feedback will be included in the final evaluation.

Key Issues

- ATM-based systems re-using existing access network infrastructures in an integrated approach
- Integration of ATM and MPEG with coax CaTV network, twisted copper pair using ADSL and APON
- Telephony on CaTV networks
- Verification of functional feasibility through a field trial
- Contribution to standards and CFS

Expected Impact

By using ATM, future networks will be able to offer both interactive and distributive services in a flexible way. However current introduction scenarios for ATM broadband see it first introduced in the business sector, followed later by the residential sector. This is based on the high introduction costs for new network infrastructure, which are a barrier to early development of the residential sector.

The project aims at solving this problem by studying and testing the re-use of existing access network infrastructures while using new techniques such as ATM and MPEG. This should lower the current cost barrier related to the introduction of new infrastructures for the residential sector and resolve the chicken and egg problem while following an evolutionary strategy.
