APPENDIX B: TELECOMMUNICATIONS NETWORK

The current FCLA Telecommunications network runs on dedicated circuits which link the 50 SUS library sites to the computer at NERDC. Those 50 sites are listed in Appendix B:1. The network uses standard IBM SNA/SDLC telecommunications protocol. IBM control units of various capacities are located at each site to support multiple unintelligent terminals.

Appendix B:2 : illustrates the new network configuration proposed in this plan. In this new configuration, each of the SUS campuses would have one or more sets of hardware installed that would support intra- building and intra-campus networks. This hardware would include either large or small routers depending upon the size and location of the sites. Remote sites will require PC-based bridges that will link them to their home libraries and their networks while the remaining smaller on-campus sites will need connectivity into the campus LANs from which connectivity to NERDC will be made.

Appendix B:3 : gives a detailed budget for the routers, bridges and PC connections needed to connect all the sites to NERDC. It does not include the figures for the PCs themselves and their attendant software and printers.
