Normal operation
Local loop active. The local loopback mode disconnects the
receive lines RL1/RL2 respective RDIP/RDIN from the receiver.
Instead of the signals coming from the line the data provided by
system interface are routed through the analog receiver back to
the system interface. The unipolar bit stream will be
undisturbed transmitted on the line. Receiver and transmitter
coding must be identical. Operates in analog and digital line
interface mode. In analog line interface mode data is transfered
through the complete analog receiver.
Slave mode

The transmit frame marker XFM is independent of this bit.
