VTs are tunneled as in the XC, they do not pass through the VT1.5 cross-connect matrix.  Figure

The XC-10G is required for OC-192 transport.  It has all the STS cross-connect and VT cross-
connect functions as the XC-VT, but supports four times the STS bandwidth of the XC and XC-VT 
cards.  The switch matrix on the XC-10G card has 1152 bi-directional STS ports capable of 
supporting 576 STS cross-connect.  The XC-10G also includes a VT switch matrix consisting of 
672 bi-directional VT1.5 ports capable of supporting up to 336 bi-directional VT1.5 cross-
connects.  As with the XC and XC-VT cards, the XC-10G card also supports VT tunneling.  There 
are with 24 of those ports available for VT1.5 switching.  Figure 2-7 is a block diagram of the XC-
10G cross-connect matrix.
