Network/Technology Infrastructure Plan
As prepared for the TUSD Governing Board Summer 2007
John BratcherNetwork Security Systems Analyst
Main Goal of plan
Develop a technology infrastructure plan to address the district technology needs to support student achievement and effective business support services for the next 5-10 years
• Supplement to the Approved Technology Plan approved by the Governing Board June 2006
• Working Document that will guide decision-making
Executive Summary• Key items about plan
• To support long-term decisions made relating to technology infrastructure
• Supports District Educational Technology Plan
• An understanding and knowledge of what infrastructure exists AND what is needed for the future
Executive Summary• Process for developing document:
• The historical context of how technology developed in TUSD
• The documentation of the current infrastructure status
• Identification of stakeholder needs and priorities using a survey of employees, parents and community members
Executive Summary• Process for developing document:
• A comparison of existing infrastructure to industry standards and recommendations
• The development of recommendations to bridge the gap to improve the infrastructure to support the educational technology plan and business services
• An analysis of the “gap” between our current status, stakeholder needs and priorities and industry standards
Executive Summary• The expected outcomes:
• Establish a district standard of “technology / infrastructure capacity” for all classrooms
• Establish a district standard of “technology / infrastructure capacity” for ALL school sites
• Establish a district standard of “technology / infrastructure capacity” to meet business support needs
Executive Summary• Analyze the differences between our existing
infrastructure and our recommended district standards to develop recommendations for necessary upgrades
• Propose sequence of actions to bring classrooms, schools, and offices up to standard
• Estimate costs and identify sources of funding to achieve these goals
Executive Summary• Potential funding sources:
• Bond*• E-Rate • Building Renewal • Other Capital Funds • Other Funds to be Determined
*guidelines have changed
Purpose• TUSD’s Governing Board approved a Five Year
Educational Technology Plan on June 13, 2006
• Goal 3 of the approved plan:
• Ensure that all K- 12 educational institutions have the capacity, infrastructure, staffing and equipment to meet academic and
business needs for effective and efficient operations.
Purpose• The following goals were established to ensure
successful implementation of the plan: • Document existing infrastructure
• Identify current and future stakeholder needs
• Establish district infrastructure standards to meet our future needs
• Develop an action plan and budget/funding parameters to move from our existing infrastructure to the upgraded district network infrastructure needed to support current and future academic and business needs
Purpose• Members:
• Lorrane McPhereson• John Bratcher• Mary Veres• Bob Holt• Cherie Odeski• Chris Van Dyke• Al Manzo• Mark Miller

Historical Context• Evolution of Technology in TUSD
• Business Computing • Student Information Management
• Local Area Networks• Individual departments/schools
• Wide Area Network• 1999 Bond Project• SFB Project
• Telecommunications• Individual circuits to PBX
TUSD’s Existing Network Infrastructure
• Converged network – voice and data travel over the same physical cables
• 5 sites act as WAN hubs
• WAN uses primarily T-1 (1.54 Mbps) and DS-3 (45 Mbps) circuits to connect schools to hub sites
• LANs primarily operate at 100 Mbps
• Internet uplink operates at 75 Mbps

Voice Services
• Historical Perspective• Each phone/fax had its
own circuit
• Current PBX• WAN Configuration
• Not completed resulting in problems with:
• 911 – provides site address not location of the phone
• Voice Message functions are limited
• Caller ID disabled
• These will be corrected with planned E-Rate funded upgrades
Specialized systems that depend on the network
• Environmental Management Control Systems (EMCS)
• Fire Alarm System• Security Alarm/ Video
Surveillance System• Access Control System• Irrigation Systems
• Distance Learning Systems
• Conference Bridge System
• Remote Access (VPN) for staff and teachers (limited)
• TUSD Television Broadcasting System
Needs Assessment/Priorities
Survey - 3000+ TUSD staff
2000 Parents/community members
• 65% of responders rated themselves as “average tech users
• 62% of responders had DSL/Cable internet access at home
• 25% of responders did NOT have internet access at home
Greatest potential for increasing student achievement
• More computers in the classroom• Access to more computer labs• Up to date websites• Interactive white boards in every classroom• More on-line classes• Digital curriculum• On-line texts• Use of digital cameras/video production• Streaming video/Video-on-demand
Greatest Obstacles
• Computers operate too slowly• Internet connections are slow• Out of data hardware/software• Lack of training for technology• Lack of technology support• Lack of instruction in technology• Limited access of TUSD network from home
