VT

(1) (Virtualization Technology) Hardware virtual machine enhancements from Intel for its x86 and Itanium families of CPUs.

(2) See Video Toaster.

(3) (Virtual Tributary) In SONET, a sub STS-1 rate, which is below 52 Mbps. A VT allows SONET to multiplex lower-capacity channels down to 64 Kbps, an important characteristic because SONET is used both as a carrier infrastructure and a customer-premises based service. A VT can operate at four speeds: 1.728 Mbps, 2.304 Mbps, 3.456 Mbps and 6.912 Mbps. A mixture of different capacity VTs can be combined into a VT Group and carried in a single STS-1. See OC.
