Signals on U-Interface
The signals SLx, TL and SP transmitted on the U-interface are defined in

indicated as follows:
a = 0/1 corresponds to ACT bit set to binary “0/1”.
d = 0/1 corresponds to DEA bit set to binary “0/1”.
The polarity of the transmitted UOA-bit depends on the received C/I-channel code:
– UAR sets UOA-bit to binary 0.
– AR, AR0, and ARX sets UOA-bit to binary 1.
– Any other C/I-codes sets the UOA to the same value as the received SAI bit. After deactivation
Data Sheet
the UOA-bit is set to binary 0 until a valid SAI-bit is received.
Re-Synchronization indication after a loss of framing (LOF)
For EI3, LSL and RSY indication the LT-side should react by applying the C/I-channel
code RES1 to allow the U-transceiver to enter the “Receive reset” state and to reset
the receiver functions.
Frame Jump
This indication signals that either a data buffer overflow/underflow has been detected
or a phase jump of one of the IOM
FJ-code is issued for a period of 1.5 ms.
U-Activation Indication
The UAI-code signals that the line system is synchronized in both directions of
transmission (see also the input ACT = 1). Maintenance bits are transmitted normally.
Activation Request Maintenance
Transmission of maintenance bits is possible.
