Bit 6: Transmit-Clock Edge Select (TCES). Selects which TDCLKI edge to sample TPOSI and TNEGI.
0 = sample TPOSI and TNEGI on falling edge of TDCLKI
1 = sample TPOSI and TNEGI on rising edge of TDCLKI
Bit 5: Receive-Clock Edge Select (RCES). Selects which RDCLKO edge to update RPOSO and RNEGO.
0 = update RPOSO and RNEGO on rising edge of RDCLKO
1 = update RPOSO and RNEGO on falling edge of RDCLKO
Bits 3 – 4: Monitor Mode (MM0 to MM1)

Bit 2: Receive Synchronization G.703 Clock Enable (RSCLKE)
0 = disable 1.544MHz (T1)/2.048MHz (E1) synchronization receive mode
1 = enable 1.544MHz (T1)/2.048MHz (E1) synchronization receive mode
Bit 1: Transmit Synchronization G.703 Clock Enable (TSCLKE)
0 = disable 1.544MHz (T1)/2.048MHz (E1) transmit synchronization clock
1 = enable 1.544MHz (T1)/2.048MHz (E1) transmit synchronization clock
Bit 0: Transmit Alternate Ones and Zeros (TAOZ). Transmit a …101010… pattern (customer disconnect
indication signal) at TTIP and TRING. The transmission of this data pattern is always timed off of TCLKT.
0 = disabled
1 = enabled
