Bits 8-11: Transmit VCAT Sequence Mapping (TVSQ[3:0]) These four bits are a BCD number that is used in the
“SQ” field of the VCAT MFI on that port. When LCAS is enabled, the internal LCAS engine controls the transmit
sequence number and reading these bits provides the current assigned sequence number for a given port. The
user should take care to not overwrite these bits when LCAS is enabled. When LCAS is not enabled, the user
can write a value to specifically assign a port’s sequence in a VCG. Note that in T3/E3 operation, only sequence
numbers 0-7 are valid.
Bit 4: Transmit Non-VCG Control (TNVCGC)
Ethernet over PDH for compliance with ITU-T G.8040.

0 = The VCAT byte position is not used for payload data. Required when placing GFP encapsulated
1 = The VCAT byte position is used for payload data. Only valid when the port is not configured as a
0 = Port n is Unused.
