DSL (Digital Subscriber Line) Service

What is DSL?

DSL (Digital Subscriber Line) is an always-on network connection operating at speeds up to 20Mbps. DSL uses the existing telephone wiring. It provides a connection directly to the campus network with full access to the Internet. DSL service is available in each Schilletter and University Village (SUV) apartment.

How does it work?

DSL connectivity is accomplished by using special equipment that is connected to both the telephone switch and the computer network. This equipment combines both sets of signals and sends them on the telephone line that leads into the apartment. In the apartment, the DSL endpoint separates the voice and data signals, routing voice signals to the telephone and data signals to the computer.

What do I need to get connected to DSL?

All Schilletter and University Village units are equipped with items 1-4 below.

  1. Paradyne DSL modem
  2. DSL power supply
  3. Telephone cord, 14 ft
  4. Telephone filter (usage optional)
  5. Ethernet card in your computer (resident provides)
  6. Ethernet cable (resident provides)
  7. Web browser (resident provides)

What do I need to provide?

Ethernet card and cable (unless your computer has a built-in Ethernet connector). Ethernet cards (10BaseT or 100BaseT) and cables are available at Tech CYte in the University Bookstore, or through computer dealers.

Who do I contact for support?

The SNAP Team is available to assist students who wish to connect their personal computer to the campus network. During fall semester move-in week, an assistant can visit your university student apartment to install an Ethernet card and configure the network settings. The team also maintains a year-round drop-off service in the Solution Center, 195 Durham Center. There is no charge to students for most standard services. Several software applications, such as anti-virus software, are available at no charge. A list of site-licensed software is available at http://www.it.iastate.edu/downloads/.
