Bit
1. On power up all register bits are set to “0”.
2. During digital loopback LOS and TAOS stay active and independent of TCLK, while data received on TPOS/TNEG/TCKLK is
1. On power-on reset the register is set to “0”.
2. T1 or E1 operation mode is determined by the PSDR settings.

These bits are set to “1” every time a DFM status change has occurred since the last
cleared interrupt in transceivers 3-0 respectively.
These bits are set to “1” every time a LOS status change has occurred since the last clear
interrupt in transceivers 3-0 respectively.
Writing to this register initiates a 1 microsecond reset cycle, except for Intel non-
multiplexed mode. When using Intel non-multiplexed host mode, extend cycle time to 2
microseconds. Please refer to Host Mode section for more information. This operation
sets all LXT386 registers to their default values.

Reserved.
Function
Setting a bit to “1” enables digital loopback for the respective transceiver.
T1 Mode
Don’t care. T1.231 compliant LOS/AIS detection is used.
E1 Mode
Setting a bit to “1” selects the ETS1 300233 LOS. Setting a bit to “0” selects G.775 LOS
mode. AIS works correctly for both ETSI and ITU when the bit is cleared to “0”. See
errata revision 10.3 or higher for a way to implement ETSI LOS and AIS.
