Cable drops are in place at East Hills Elementary School, George Westinghouse High School and the Hill House Association. TCI is now in the process of establishing and tuning the return channels for these sites which are required for the provision of data services via ChannelWorks, and we are working with TCI to determine the best paths for internal distribution of the necessary data service at each of these sites. All of the new links will use the common fiber path from TCI's head end.
ISDN lines have been installed at Mellon Institute, Hill House and Phillips Elementary School. Tests were performed on lines attached to a Northern Telecom switch that serves Mellon Institute, and additional tests scheduled for the AT&T; switch that will be used at other project sites. It is anticipated that ISDN will be used as a backup for all ChannelWorks sites pending the acquisition of reliable data on the performance of the ChannelWorks links.
Server development work continued with a port of the network services software used by Common Knowledge: Pittsburgh to DEC Alpha workstations running Digital Unix. Following the completion of beta tests of this server, a unit will be deployed at Carrick High School to provide network services for the school and permit extensive performance testing of the high-speed link to this school.
Web foundry machines were received and configured for deployment at the Carnegie Library and Hill House. Additional machines are on order for school sites associated with the project. Sites have a choice of Foundries built on Pentium PCs or Apple PowerMacs.
The Hill House online presentation has been installed on the Hill House server, where it can be accessed at http://hillhouse.ckp.edu/hhcan/home.html The exhibit now includes a number of enhancements such as clickable images and backgrounds. Pending establishment of high-bandwidth connectivity to Hill House, the server has been placed at the Common Knowledge: Pittsburgh central site in Mellon Institute.
Through the aupsices of the Office of the Mayor of the City of Pittsburgh, plans have been developed to extend connectivity to three additional sites in the Hill District - Youth Fair Chance, the New Beginnings Learning Center and the Wadsworth Hall Community Center. Using funds available through the Weed and Seed program of the United States Department of Justice, a connectivity hub will be established at Hill House with ISDN links to each of the satellite sites. This arrangement will provide a model for the city to use for neighborhood connectivity at other sites around the city.
The broad range of material included in the exhibit make it a valuable educational resource and a fascinating touchstone for Pittsburgh residents. Hypertext "photonotes" provide textual information on images used to illustrate neighborhood narrative pages. A "Photographers" section has been added to provide biographical information on the photographers represented in the exhibit. This section was largely contributed by Peggy Domer, an intern from the University of Pittsburgh's School of Library Science, who has been working with Barry Chad. These added elements are designed to increase viewer interest in the exhibit and provide the sort of depth possible online in a hypertext presentation. Demonstrations of the exhibit continue to be given both locally and as part of conference presentations. Viewer response continues to be very positive.
In the course of organizing these meeting we have seen the need to establish an ongoing demonstration facility. This will likely include a network information server, two user devices (one PC and one Apple Macintosh), a network concentrator and an ISDN router.
Common Knowledge: Pittsburgh staff have participated in several conferences and workshops during this quarter. These events included meetings sponsored by DECUS (Digital Users' Group), the Pennsylvania Information Highway Consortium, the Rural Datification Conference and a workshop on cost-effective networking of schools and homes sponsored by John D. and Catherine T. MacArthur Foundation. These interactions are helping the project to define a unique and coherent vision of community networking, which brings together a broad range of community participants and spans a wide range of network applications. We believe that this breadth is essential for the development of a sustainable regional networking infrastructure.
