UD's Dial-In Access Numbers

In order to access the University's central computing systems by modem, you must dial one of the following telephone numbers.

You are liable for any potential telephone charges for calling UD's modem pool. Therefore, whenever possible, make sure the phone number that you select is a local call from your dialing area. Do not use University modem numbers from outside your local calling area as main or alternate numbers unless you are willing to pay the phone charges.

Pre-paid phone cards are not set up for dial-in modem service. If you need that service, investigate purchasing a data/Internet pre-paid phone card from the telephone services vendor of your choice.

  • Note to Maryland users: Even if the telephone call to the modem pool is toll free, you may still be charged "message unit charges" if you do not have unlimited local calling from your home phone. Please check with your telephone service provider to find out whether you have unlimited local calling from your home phone.
  • Currently, the Newark connections are configured so that if you do not use your connection for 20 minutes (if no data passes in either direction), your connection will be dropped.
  • The three Maryland , Kent County (DE), and Sussex County (DE) phone numbers all share one pool of modems.

Configuration summary

You must have your system configured properly in order to communicate with University's central systems. Check your computer modem's settings to make sure they match the following:

ParityData BitsStop BitsTerminal
None81 vt100 or vt102up to 53,000 bps

These are the "usual" settings for most Internet Service Providers.

You will connect to the University's network using Point to Point Protocol (PPP). A PPP connection gives you full access to the Internet; however, access is much slower than when you are on campus. Note that you must have a valid account on the University's central UNIX systems in order to dial-in to the University's network.

If you have a valid University computing account, after you have configured your PPP software properly, the terminal servers will automatically connect your system to the network without your typing anything. After you are connected, you can connect to whichever system you need to use with desktop clients such as Telnet, FTP, Fetch, Microsoft Internet Explorer, and Netscape Navigator.
