Network Access Policy
Introduction
This document establishes the policy for access to and from the Health Science Center computer network. This policy is designed to encourage efficient use of the computer network while minimizing the potential exposure to damage that may result from unauthorized use.
Definitions
T&N: The Department of Telecommunications and Networking (T&N) within Information Management and Services at UTHSCSA.
CR: The Department of Computing Resources (CR) within Information Management and Services at UTHSCSA.
ISO: The Information Security Office (ISO) within the Department of Computing Resources.
DMZ: Demilitarized Zone, a networking term used to describe an isolated network segment that has open access to the public network (Internet) but very restricted access inside the firewall to the protected side of the computer network. The DMZ serves as a security buffer between the two sides.
FTP: File Transfer Protocol, a server/client application for transferring files between network devices.

Network Access Policy (HOP)
Policy
The purchase, lease, subscription, or rental of telephones, telephone services, signal transmission services, or voice processing equipment is provided as a service to the other departments of the Health Science Center. The equipment shall be administered by T&N, ensuring that it is properly acquired; State reporting requirements are met; proper maintenance is performed; compatibility with existing equipment is maintained; facilities are optimally used; and the communications needs of the department are met at the least cost.
LOST OR STOLEN EQUIPMENT
Policy
Each department is responsible for the care of the equipment assigned by T&N. If a piece of equipment is lost, stolen, or damaged due to abuse, a fee equal to the replacement cost of the equipment will be charged to the responsible department.
LONG DISTANCE SERVICE
Policy
The Health Science Center uses the State communications network (TEX-AN) for routing the majority of long distance telephone calls. Therefore, by State law, the Health Science Center is restricted from routing any long distance call that is not placed for the purpose of conducting University or State business. Telephone authorization codes and reports detailing the long distance calls made with each authorization code are produced by T&N to assist in the control of unauthorized calls. It is the responsibility of each department to ensure that authorization codes are kept secure and that the monthly reports are reviewed by a departmental authority to ensure that authorization codes are used only for official business of the University. Review must be complete and any unauthorized calls reimbursed by the employee within 30 days after reports are received by the department.
Policy
A University-owned mobile telephone and mobile telephone air-time service are to be used for official University business only. However, the Health Science Center recognizes that personal calls will sometimes be necessary. When the mobile telephone is used for a personal call, the individual is responsible for the cost of that call. The telephone user should make note of personal calls and write a check to UTHSCSA after review of the monthly call detail. Their personal check should be submitted to the Bursar’s Office for deposit to the account number billed for the cost of the call. If the mobile telephone has a flat rate airtime plan, the customer is responsible for reimbursing the Health Science Center when personal calls cause the plan threshold to be exceeded. In this case, personal calls must be reimbursed up to the amount over threshold. It is recommended that a minimum of 90% of the total calls be for Health Science Center business purposes. Calls home to receive patient messages, to inform of a delay to return home, or to stay in touch when out of town, may be considered business calls. Typically, these calls should last no more than 10 minutes. For further information regarding these policies and services, please refer to the T&N homepage http://www.uthscsa.edu/tn or contact Customer Services at extension 7-2061.
Because of the potential for fraud, mobile telephones are restricted from making international long distance calls. If a mobile telephone user has the need for making this type of call on a routine basis, the restriction can be removed.
PERSONAL MOBILE TELEPHONE EXPENSE REIMBURSEMENT POLICIES
Policy
It is the policy of the Health Science Center that all telephone service purchases be made through T&N. The Health Science Center maintains a contract with a vendor for air-time. Reimbursement for air-time charges incurred on a personal mobile telephone air-time contract will be made at a rate not to exceed the University contract rate. No reimbursement will be made from any University account for monthly service charges, special features, or telephone equipment, or other charges and credits.
Most mobile telephones carry a flat rate airtime package. The formula for reimbursement of business calls is the monthly cost of the airtime package plan divided by the number of minutes provided in the plan. This is the cost per minute. The reimbursement rate allowed is the number of minutes used for Health Science Center business multiplied by the airtime package cost per minute. Minutes used above the packaged rate plan are generally charged at a higher rate. Calls charged at this rate will be reimbursed at the package rate, not the overtime rate.
