Abstract
In 1994 Swiss Telecom PTT has taken the initiative to operate two large scale multimedia trials. The first trial became operational in September 1995 and currently still runs in Grenchen (a blue collar, German speaking small city), with 400 households connected to the central server over telephone wires, using ADSL technology. The second trial became operational in May 1996, also running with 400 households in Nyon. In Nyon (a rich, French speaking suburb of Geneva) the subscribers are connected to the central server over a CATV network, using 64 QAM for the downstream broadband connection and PSK for the two-way, low-speed, control channel.
After a short introduction about the architecture and the technology used in the trial, this paper focuses on the organisation and operation of the trial, the services offered, the households connected and the most important results of the trials.
