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.
