Unidirectional Path Switch Ring Mode Control. Logic 1
activates the UPSR mode of operation. When the device
is programmed for UPSR mode, the transmitted REI-V,
RDI-V, RFI-V, and ERDI-V are based on the receive condi-
tions. Otherwise, the transmitted LOPOH is a copy of the
received overhead bytes.
VT Pointer Interpreter Mode Control. Logic 1 tells the
pointer interpreter to transition into the inc and dec states
based on 8 of the 10 I and D bits. Otherwise, the pointer
interpreter transitions into the inc and dec states based on
majority rule.
activates BIP-2, TC-BIP-2, REI, and TC-CRC-7 counts
based on single bit errors. Otherwise, errors are counted
on a block basis.

Logic 1 selects VT1.5/TU-11 and logic 0 selects
VT2/TU-12 group type. Group 1 is the LSB.
