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
![Page 22: Network/Technology Infrastructure Plan As prepared for the TUSD Governing Board Summer 2007 John Bratcher Network Security Systems Analyst.](https://reader036.fdocuments.in/reader036/viewer/2022062620/551a4b59550346a4248b5ebd/html5/thumbnails/22.jpg)
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
