Use the Cross-Connect tab to provision the VT payload type to VT-1.5 (default),
VT-2, or VT-1.5 and VT-2 (Mixed Mode). VT-2 or VT1.5 and VT-2 (Mixed Mode) can only be selected if an XCVXC cross-connect is in the node. If the cross-connect is not an XCVXC, these options appear gray and the default VT1.5 mode is selected.
