ATM & MetroNet 2000• Currently supporting voice and data
• Core ATM switches installed in Columbia & Charleston
• Agency Sites in Capital Complex
• OC-3’s to SC Net and BellSouth ATM
• DS-3 Frame Relay
• DS-3 SMDS
• InterLATA ATM in “Megabit Increments”
• ATM to InfoAvenue (ISP) in “Megabit Increments” with bursting
• Internet 2
SCINET ATM Backbone• Provided by carriers
• Enables Integration on ATM backbone:– Frame Relay FRF-8 in place– K-12 Network conversion to F/R underway– H.320 Video links in progress– Electronic Tandem Network next– SNA Networks converting to TCP/IP
• Internet - 4 LATAs
• Internet 2 – In place
Best of Both Worlds
• Allows High Speed Access at Main Location, Low Speed Access at Remote Sites
• Ensures Each Site is Provided a Solution that Delivers the Best Price Performance
• Service Interworking (FRF-8) provided by IXC
