10 VT/TU Mapper Registers
10.1 VT/TU Mapper Register Descriptions
The following tables describe the functions of all bits in the register map. For each address, the register bits are
indicated as either read/write (R/W) or read only (RO), and the value of the bits on reset is given.

VT/TU Signal Degrade Delta Bit. Logic 1 indicates a
change in the signal degrade condition based on the inter-
nal bit error rate detector.
VT/TU Signal Fail Delta Bit. Logic 1 indicates a change
in the signal fail condition based on the internal bit error
rate detector.
H4 Mismatch Delta Bit. Logic 1 indicates a change in the
H4 loss of multiframe condition.
VT/TU Mapper Ready. A 1 indicates that the VT/TU map-
per is ready for microprocessor reads and writes.
Reserved.
Block Version Number. These bits identify the version
number of the VT/TU mapper.
Block ID Number. VT_ID returns a fixed value (0x02)
when read.
