If a circuit is provisioned using a terminating card, the terminating card provides the C2 byte. A VT
circuit is terminated at the XCVT, XC10G, or XC-VXC-10G card, which generates the C2 byte (0x02)
downstream to the STS terminating cards. The XCVT, XC10G, or XC-VXC-10G card generates the C2
value (0x02) to the DS1 or DS3XM terminating card. If an optical circuit is created with no terminating
cards, the test equipment must supply the path overhead in terminating mode. If the test equipment is in
pass-through mode, the C2 values usually change rapidly between 0x00 and 0xFF. Adding a terminating
card to an optical circuit usually fixes a circuit having C2 byte problems.
