Data Sheet
3.7
The following test and diagnostic functions for the D-channel are available:
– Digital loop via TLP (Test Loop, TMH register) command bit (figure 54): The TX path
– Test of layer-2 functions while disabling all layer-1 functions and pins associated with

of layer 2 is internally connected with the RX path of layer 2. The output from layer 1
on DD is ignored. This is used for testing layer 2 functionality excluding layer 1 (loop
back between XFIFO and RFIFO).
them (including clocking) via bit TR_CONF0.DIS_TR. The HDLC controller and codec
part can still operate via IOM-2. DCL and FSC pins become input.
