Infrastructure Services

There are 293 buildings on campus and 8 offsite facilites that Telecommunications maintains.  This includes:

  • Fiber and Ethernet cabling within buildings

  • From the Telecommunications spaces to each phone/data drop

  • 327 Telecommunication Rooms containing switches and major fiber splices

Campus Locations

Fiber optic and copper cables are running between all buildings on campus. Miles and miles of fiber and copper are required to maintain all of the connections.  There are 92 maintenance holes of various sizes.  TNS is responsible for maintaining all fiber and copper plant including making sure backhoes and blasting do not disrupt service.  

Fiber optic cable and copper cables running is between three major switch rooms

  • Mann Hall
  • Waterman
  • Southwick

TNS provides connections for:

  • Fire Alarms
  • Building Control Systems
  • CatCard Services
  • Campus closed circuit cameras
  • Campus Cable TV
  • Wireless Access Points

Campus Buildings

TNS designs and maintains all fiber and ethernet cabling within all the buildings on campus.  This includes the wiring from the telecommunication spaces to each port and wireless access point.  There are 327 telecommunications rooms containing switches and major fiber splices.

There are one to several telecommunications rooms per building.  They contain fiber connections to conduits and between locations as well as switches.  There are a wide variety of rooms in various stages of upgrades.

The good telecommunications room

New and renovated buildings have good wiring capable of high speed connections (100 mbit or gigabit) Category 5e or Category 6.  

Many older buildings have very old wiring that are not capable of modern connection speeds and not easily updated.  Installling new wiring is complicated by lack of a pathway to run wires and the presence of asbestoes in many areas that requires expensive abatement prior to re-wiring.  The physical characteristics of old wiring does not support current network speeds.  Newer computers and applications often do not work well on old wiring.  Many buildings, such as Waterman, have a mixture of new and old wiring.

Remote Sites

TNS maintains connections to and within 8 remote sights in Chittenden County via a "county ring" of fiber.  The remote sights are:
  • Rubenstein Center
  • Innovation Center
  • Freezer Farm
  • BioResearch Complex
  • Technology Park (Data Center)
  • Fort Ethan Allen
  • ETS and Procurement
  • Colchester Research Facility

Fiber Ring


There are 1100 wireless access points as well as centrally managed enterprise access points .  TNS is resposible for mainitaining the cabling infrastructure that each access point requires.  The access points feature automatic configuration adjustments to fine tune performance.  The signal for each access point is  balanced against othe aceess points to avoid interference.  These are designed for use in large dense wireless installations.  All residence halls are completely covered by WIFI.  Most classrooms and administrative buildings have at least partial WIFI.  There can be a maximum of 10,000 simultaneous users.  Below is a graph showing the number of users of the UVM wireless 1 week vs. 1 year.
