Tx B2 Selection
The B2 Byte is calculated and placed in the Insert B2 Location when DISTB2R (CR17; 1DD[H], Bit 1) = "0".
The calculation is Even Parity, independently performed, in parallel, over the eight bit positions of all bytes
except the nine Section Overhead Bytes. The value calculated for Frame n is placed in the B2 Byte of Frame
n+1. If DISTB2R = "1" and if TCLK = "0", the B2 Byte Incoming at the Tx Terminal Port will be output at the Tx
Line Port.
The B2 value output on the Tx Line will be Exclusive-OR gated with the Tx B2 Error Mask (151[H]) prior to
insertion. As has been discussed previously, TRERR controls the resetting of the mask.
Tx K1 and K2 Selection
K1 and K2 Byte Selection is controlled by TRAPS and EXAPS (CR8; 1F8[H], Bits 2 and 1). The source selec-
tion is shown below where: & = the logical "AND" function, + = the logical "OR" function, and = represents a
control state.
Tx D4-D12 Selection
D4-D12 Byte selection is controlled by TRLD (CR8; 1F8[H], Bit 6) and TXLDEXT (CR15; 1DF[H], Bit 7). The
source selection is shown below where: & = the logical "AND" function, + = the logical "OR" function, and =
represents a control state.
In the OW/APS Application, the external source for the Bytes will be the Tx Line DCC Port. In the All TOH
Application, the external source will be either the Tx Line DCC Port or the Tx TOH Port, as controlled by OA
and LDCCEN (CR17; 1DD[H], Bit 6).
