LT-T mode
In this mode the frame relation between S/T interface and IOM-2 is flexible.
LT-S/NT mode
In the state F7 (Activated) or if the internal layer-1 statemachine is disabled and XINF of
register TR_CMD is programmed to ’011’ the B1, B2 and D bits are transferred
transparently from the S/T to the IOM-2 interface. In all other states ’1’s are transmitted
to the IOM-2 interface.
Note: In intelligent NT the D-channel access can be blocked by the IOM-2 D-channel
