Maui Community College Data Communications

A new conduit system connecting each Kahului campus building by fiber with the new Ka`a`ike Technology Center was completed March 2002.  Each campus facility has12 singlemode and 6 multimode fibers for special video functions that terminate in Ka`a`ike 117;  6 singlemode and 12 multimode fibers connect to Computing Services in Ka`a`ike 221 and are used for computing data communications.  Most buildings connect to the campus Cisco 6006 layer-3 switch in Ka`a`ike 221 using fast Ethernet (100mbps), but buildings with high volume traffic, such as the Learning Center complex, Laulima and Ka Lama, connect at gigabit speeds (1000mbps).

A second switch (Cisco 6506), located in Ka`a`ike 106A, is used primarily for the interactive distance education teleconferencing systems, SkyBridge and the Hawaii Interactive Television System.  The distance education classes are carried over an OC3 (100 T1s) microwave link to the University of Hawaii at Manoa and from there to other branches of the University, including MCC's outreach education centers on the islands of Molokai and Lanai and in Hana--each of which also has OC3 connectivity.  The Cisco 6506 has a gigabit connection with the Cisco 6006 switch, providing redundancy.  Actually, both connect to a pair of Cisco 3508G gigabit switches, which, in turn, connect to a LuxN WS-3208 which transmits data at gigabit speeds over fiber to the Maui Research and Technology Center (MRTC) in Kihei, Maui. MCC data, along with other branches of the University and State Offices then share an OC3 fiber link to Oahu and the University of Hawaii at Manoa. This link is used for traditional data communication, while the microwave OC3 link is used primarily for teleconferencing; however each link provides valuable redundancy in case the other should fail.

Each building on the main campus in Kahului and at each outreach education center has a data room or closet.  The main swich for the building (either Cisco 3524 or 2924 or Allied Telesyn 8224XL or AT-FS709FC, depending on building traffic) is located in the data room along with necessary hubs which connect with computers in the building via Category 5 or 5e cable.  The Ka`a`ike Technology Center also has fiber to offices, specific labs and classrooms, in addition to Category 5e.
