is disabled.
The transmit data of the transmitter is looped back internally to the receiver. The data
of the IOM-2 input B- and D-channels are looped back to the output B- and D-
channels.
The S/T interface level detector is enabled, i.e. if a level is detected this will be
reported by the Resynchronization Indication (RSY) but the loop function is not
affected.
Depending on the DIS_TX bit in the TR_CONF2 register the internal local loop can be
transparent or non transparent to the S/T line.

register has to be programmed and the loop has to be closed externally as described

The S/T interface level detector is disabled.
This allows complete system diagnostics.
channel information received from the line card is transparently forwarded to the
output IOM-2 D-channel. The output B-channel information on IOM-2 is fixed to ‘FF’
