Bit 7: Device CODE ID Bit 7 (ID7).
This bit is zero for the 75
Ω impedance part number and one for the 120Ω
impedance part number.
Bits 6 to 3: Device CODE ID Bits 6 to 3 (ID6 to ID3).
These bits tell the user the number of ports the device
contains.
Bits 2 to 0: Device CODE ID Bits 2 to 0 (ID2 to ID0).
These bits tell the user the revision of the part. Contact the
factory for details.

Bits 7 to 0: Analog Loopback Configuration Bits Channel n (ALBCn).
When this bit is set, LIUn is placed in
analog loopback. TTIPn and TRINGn are looped back to RTIPn and RRINGn. The data at RTIPn and RRINGn is
ignored. The LOS detector is still in operation. The jitter attenuator is in use if enabled for the transmitter or
receiver.

Bits 7 to 0: Remote Loopback Configuration Bits Channel n (RLBCn).
When this bit is set, remote loopback is
enabled on LIUn. The analog-received signal goes through the receiver and is looped back to the transmitter. The
data at TPOSn and TNEGn is ignored. The jitter attenuator is in use if enabled. Note: LIUn is placed in dual
loopback if DLBC:DLBCn is also set.
