The ISAC-SX TE provides test and diagnostic functions for the S-interface and the D-
channel:
• Digital loop via TLP (Test Loop, TMD register) command bit

of layer 2 is internally connected with the RX path of layer 2. The output from layer 1
(S/T) on DD is ignored. This is used for testing ISAC-SX TE functionality excluding
layer 1 (loopback between XFIFOD and RFIFOD).
