ADTRAN's ATLAS Helps School District Integrate Voice, Data and Video Over T1 & PRI
Anticipated savings of more than $70,000 per year!
The school system has a decided advantage in that the State of California offers low T1 prices for educational institutions. With ADTRAN's ATLAS and TSU products, the entire school system is now enjoying voice, data, and video integration at lower costs than ever before achieved. Voice calls can now be made to any other school or district office without long distance charges. Each school's LAN is inter-networked, and the schools can dynamically video-conference with one another or with an outside source.
Datacomm Support Company, Inc. (DSC), one of ADTRAN's first distributors established in Southern California, is a Value Added Reseller and systems integrator offering end users and resellers total solutions for voice, data, video and fax communications over LANs and WANs. DSC began working in 1997 with Saddleback Valley Unified School District (SVUSD), which has one district office, one recreation department and 36 remote elementary, intermediate and high schools all served from the same Pacific Bell central office. SVUSD installed T1s to all of its remote schools, taking advantage of Pacific Bell's special rate for school districts of $90 per month. To fully utilize the capacity of the T1s, ADTRAN's Smart16 Shelf with TSUs is used at the district office with TSU 100 units at the remote schools. ADTRAN proposed that SVUSD look at integrating voice over its T1s using ATLAS 800. ADTRAN and DSC designed a system to integrate voice, data and video for the district and 37 remote schools. Assigned to this account from DSC were Loren Grube, Account Manager, and Khoi Nguyen, Sales Engineer. ADTRAN offered its complete support from the start, partnering with DSC as the preferred vendor on this account.
The district office equipment includes ATLAS 800s with a combination of T1/PRI and Nx56/64 data modules. The T1/PRI Modules support T1 connections to the 37 remote schools for data, T1 interfaces to the ROLM PBX for voice, and DSX-1 interfaces to video-conferencing equipment. Because of the unique Fractional PRI feature in ATLAS 800, Saddleback is able to split out six DS0 channels for each video-conferencing session. Two configuration options are set up so that the school can best utilize all of the T1 channels depending on current traffic requirements.
At the remote elementary schools, the TSU 600e, a six-slot T1 DSU/CSU with Ethernet SNMP interface, is used. The Dual Nx56/64 V.35 Module is interfaced to the router for data. Quad 2FXS+ modules interface with the PBXs for voice, and DSX-1 modules were installed to support a video (PRI or T1) interface. Ten DS0s are set aside for data and eight for voice.
The intermediate and high schools each have two T1 circuits. One T1 is dedicated to data using existing TSU 100s. The other T1 supports voice and video using the TSU 600e. Adding to the versatility of the system, voice is supported by the Quad 2FXS and E&M Modules, and video applications are supported by the DSX-1 interfaces. Also installed in the TSU 600e are the Drop & Insert Module and the Dual Nx56/64 V.35 Module for equipment backup in case the existing TSU 100s fail.
Pete Vavra, ADTRAN's field applications engineer, provided on-site engineering for the initial demonstration at the SVUSD district office using one ATLAS 800 and three TSU 600e units at remote schools. The demonstration was a success- transmitting data, voice and video. Saddleback decided to proceed with the deployment of ADTRAN products at all of their 37 schools.
