Data Sheet
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.
local loop described above. Additionally the EXLP bit in the TR_CONF0 register has
to be programmed and the loop has to be closed externally as described in
The S/T interface level detector is disabled.
This allows complete system diagnostics.
