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
