Glossary of Terms

  • Campus wired network: Any Cat 5 or higher network connection in a building that is on the Urbana-Champaign campus.
  • Campus wireless network: Any wireless connection (e.g. IllinoisNet, eduroam, QuickConnect, UIUCNet) provided by CITES on the Urbana-Champaign campus.
  • On campus still using Cat 3 connections: Some jacks have not been upgraded to Campus wired network standards. These jacks are generally in older dormitories and University-owned houses. Location information for these jacks is not currently stored in Pinnacle, the CITES billing software. Any calls to 911 on the Cat 3 network will be directed to the ECRC.
  • Off campus not on VPN: Any internet connection that does not include the campus wired or wireless networks (e.g. Home internet, public WiFi, 3G/4G cellular connections).
  • Off campus on VPN: Any internet connection that does not include the campus wired or wireless networks (e.g. Home internet, public WiFi, 3G/4G cellular connections) and through which a VPN connection to the campus network is established.
  • Hard Phone: An IP phone is a hardware-based phone for making telephone calls over the Internet. IP phones need to be plugged into a network / data jack instead of the traditional voice jack.
  • Softphone: A softphone is a software program (Microsoft Lync in our case) for making telephone calls over the Internet using a general purpose computer, rather than using dedicated hardware, such as an IP phone. A softphone is usually used with a computer audio accessory such as a headset connected to the sound card of the computer, or with a USB phone.
  • Computer Audio Accessory: Computer audio accessory is a device that plugs into your computer to carry audio, usually in both directions (speaker and microphone). Examples are headsets that connect to the sound card or USB port of the computer, USB phones. These accessories are meant to be used in conjunction with the softphone and not alone.
  • Standalone IP Phone: A hard phone that does not integrate with a computer. These devices must be plugged in to a network (data) jack.
  • USB-tethered IP Phone: A hard phone that is integrated with the Lync Client running on a computer. The device must be connected to a computer via a USB connection in order to provide full integration. These devices also must be plugged in to a network (data) jack.
  • Lync Client for Windows: Microsoft Lync is the softphone that is used with UC at Illinois. The Windows version of Lync is fully integrated with the UC E911 system. The computer on which Lync is running must have a network connection (wired, wireless; on campus, off campus) and the user must be logged in to Lync in order to make calls. Many users integrate computer audio accessories to enhance the audio and/or video experience of the softphone.
  • Lync Client for Mac: Microsoft Lync is the softphone that is used with UC at Illinois. The Mac version of Lync is fully integrated with the UC E911 system. The computer on which Lync is running must have a network connection (wired, wireless; on campus, off campus) and the user must be logged in to Lync in order to make calls. Many users integrate computer audio accessories to enhance the audio and/or video experience of the softphone.
  • Other Operating Systems: No other operating systems are being supported at this time. For other operating systems (i.e. Linux), a hard phone is the recommended deployment solution.
  • Smartphones: Microsoft has released Lync clients for Windows, Android, and iOS Smartphones. However, these clients are not supported as part the UC at Illinois service. Support for these clients is expected, but no timeline exists for deployment.
  • Thin Client: A computer or a computer program which depends heavily on another computer and its server to fulfill its traditional computational roles. There is currently no E911 support for any type of Thin Client. A hard phone is the recommended deployment solution. Given the growing use of Thin Clients, CITES will begin working with stakeholders to support Thin Clients in the future. This will occur following the initial deployment of the production E911 system. Interested IT Pros with Thin Client deployments should contact cites-E911@illinois.edu for additional information.
  • Remote Desktop: A Windows feature that allows you to have access to a Windows session from another computer in a different location. Windows Remote Desktop is not a supported environment for using Microsoft Lync.
  • Other Remote Connections: Remote connection applications (e.g. VNC) are not supported for using Microsoft Lync.
