Most campus offices will use the campus switch for telephone line services. Listed below are additional telephone line types that are available for off-campus facilities and other special purposes.

Centrex or Centranet Phone Line Installation

Centrex is an AT&T telephone line while Centranet is a Verizon telephone line. Both are analog or digital lines used as a substitute for a business telephone system. If you can dial a five-digit extension rather than the seven-digit phone number to reach someone on campus, then you are on one of these systems. Centranet is associated with the following prefixes and is available on the Health Sciences and University Park campuses:

Campus LocationArea CodePrefixExtensionUniversity Park 5ESS2137400-xxxxUniversity Park 5ESS2138211-xxxxHealth Sciences 5ESS3234422-xxxx

For locations off campus, Centrex may be available with five-digit access. Not all off-campus locations have five-digit access back to the Health Sciences or University Park campuses. Centrex is associated with the following prefixes and is available on the Health Sciences and University Park campuses:

Off-campus Centrex Phone Line Installation

Centrex is an AT&T analog or digital telephone line used as a substitute for a business telephone system offering the following benefits:

  • Centrex is a better analog line than the Measured Business telephone line for small, remote office locations that need to transfer phone calls to an external location.
  • The price of a Centrex telephone line is almost identical to that of a Measured Business telephone line, and Centrex customers receive priority service from the carrier.
  • Centrex offers a feature called Direct Inward Dial/Direct Outward Dial (DID/DOD) that allows you to transfer an incoming call to any other telephone number in the world. This is very useful for businesses with telecommuters and branch offices. Moreover, calls to other Centrex lines within the same area code and prefix are free.

The monthly charge for an off-campus Centrex telephone line does not include charges for toll and long-distance usage. Calls to 900, 976, or 700 services are not allowed on any university telephone. If cable and wire already exist up to the jack in the wall, the installation cost includes a service technician labor charge plus vendor installation charges. However, if cable and wire do not already exist up to the jack in the wall, Outlet Installation charges will also apply.
