3.10 Transmit Hybrid Cancellation

Table 21 lists the transmit hybrid cancellation characteristics. Unless stated otherwise, test conditions

are: ACZ[3:0]=0000 (600 Ω termination), THEN=1, ATEN=1, DAA[1:0]=01, TXBST=0. TXM is externally

fed back into the 73M1916 to effect cancellation of transmit signal.
