@conference {2813, title = {Tele-working services from the Greek PTT}, booktitle = {3rd International Conference on Networking Entities-The organisational impact of telematics, Neties{\textquoteright}99, Krems, Austria}, year = {1999}, month = {18 - 19 March}, pages = { 17 - 22}, abstract = {During the last years tele-working methods that utilise network resources and services are gaining wide acceptance. Interestingly enough not all the enterprises that want to and can use tele-working are doing so. The main obstacles in adopting and implementing tele-working techniques are lack of technical knowledge, poor infrastructure, and lack of support. In Greece the main PTT organisation, as part of its strategy to offer integrated Telematic services in various areas, designed and is currently testing under several tele-working scenarios various services that will be offered in suitable packages. The services offered include telephony services, basic and advanced network services etc. The packages to be offered cover a wide area of tele-workers, including tele-workers from home, mobile tele-workers, telecommuters etc. The packages also cover the need to establish suitable infrastructure for the tele-workers in the enterprise{\textquoteright}s premises, and the establishment of telecentres/telecottages or satellite centres.In order to effectively test all the proposed services a pilot network has been established. The network is based on ISDN links and it consists of a few central nodes (i.e. representing enterprises{\textquoteright} premises) and several remote nodes (some of them mobile) representing for the teleworkers. The central nodes are equipped with an ISDN PBX, an enterprise server, and a router. These nodes are connected to the public ISDN network via a few Primary Rate Interface (PRI) ISDN links. The tele-workers{\textquoteright} nodes are equipped with communication devices, such as telephones and facsimiles, and with personal computers. The nodes are connected to the public ISDN network via one or a few Basic Rate Interface (BRI) ISDN links. The initial tests show very promising results. The offered integrated services are easy to use and very reliable. As a consequence the tele-workers exhibit improved performance.}, author = {Christos Bouras and Vaggelis Kapoulas and B Mamalis} }
