070—Transmit Framer Configuration (TCR0)
TCR0 selects the offline framer's criteria for recovery of transmit frame alignment and determines the output of
transmit frame and alarm formatters overhead bits. In addition, TCR0 works in conjunction with TCR1
[addr 071] and TFRM [addr 072] to select the transmit online frame monitor's criteria for loss of frame
alignment and to select which overhead bits are supplied by the transmit frame and alarm formatters.
Unused bits are reserved and should be written to 0.

Transmit CRC6 includes F-bit—Determines if the F-bit is included in the CR6 remainder
calculation in T1 mode (T1/E1N = 1). This bit is ignored in E1 mode (T1/E1N = 0).
0 = T1 ESF CRC6 calculation is performed on the
transmit data including a 1 in place of the F-bit.
1 = T1 ESF CRC6 calculation is performed on transmit
data including the F-bit.
