Other workstations include two Silicon Graphics machines. There are a variety of supporting communications facilities available to students and faculty. For off-site users, there are 12 phone lines dedicated to incoming modems and 4 lines for outgoing modems. Both 1200bps and 2400bps service is supported. Fiber-optic links supply Ethernet access to the entire campus.
Microwave links contribute high-speed data paths to facilities at other sites in North Carolina.
Duke's machines are connected via these links to NSFnet and the rest of Internet. These systems all run Berkeley 4.3 UNIX and are connected to the Department of Computer Science via the MCNC Microwave System. MCNC serves as the central site for a state-wide communications network and as the gateway to the Internet. Incoming students may wish to wait until they arrive on campus to purchase a computer at a special student discount through Duke's computer store.
