We continued our effort on the CASA testbed project in 1994. The long-awaited OC-48 link between SDSC and Los Alamos National Labs (LANL) was turned over to us by MCI and US-West in June 1994. The HIPPI/SONET (H/S) gateways, however, were limited at that time to supporting only 5 OC-3c channels. Our effective link bandwidth was thus 5 * 132 Mbps, or 660 Mbps (each OC-3c channel provides about 132 Mbps after SONET overhead is subtracted).
