Telephone and Data Network Services

ITS provides USC schools and departments with basic telephone and data network services for a Technology Connection Charge (TCC). Schools and departments can also choose enhanced telephone services for an additional fee.

The basic telephone services included in the TCC are dial tone, voicemail, and 5-digit (extension) dialing; local and long-distance calling within the U.S.; troubleshooting for issues related to phone jacks; and maintenance of your building’s interior telephone wiring.

Schools and departments may choose to maintain their own telephone sets or select the ITS telephone maintenance plan for an additional fee.

Schools and departments may choose to purchase new digital telephone sets from ITS or from a third-party vendor.

Data Network Services

Data network services included in the TCC are wired and wireless network access. The TCC provides maintenance for the data network up to, but not inside, each building.

Schools and departments may choose to have ITS support their internal (intra-building) data network for an additional 12% of their total TCC. For more information, see the Intra-Building Network Support page.

Introducing TMIS

ITS has replaced the Telecommunications Management System (TMS) with the new Technology Management Information System (TMIS) to integrate and streamline the ordering of voice and data services at USC. For additional information on TMIS, see
