Data Sheet
F6 Synchronized
The receiver has synchronized and detects info 2. Info 3 is transmitted to synchronize
the NT.
F7 Activated
The receiver has synchronized and detects info 4. All user channels are now conveyed
transparently to the IOM interface.
To transfer user channels transparently to the S/T interface either the command AR8 or
AR10 has to be issued.
F8 Lost Framing
The receiver has lost synchronization in the states F6 or F7 respectively.
Unconditional States
Loop A Closed (internal or external, see chapter 2.3.10.1)
The SCOUT loops back the transmitter to the receiver and activates by transmission of
info 3. The receiver has not yet synchronized.
For a non transparent internal loop the DIS_TX bit of register TR_CONF2 has to be set
to ’1’.
Loop A Activated (internal or external, see chapter 2.3.10.1)
The receiver has synchronized to info 3. Data may be sent. The indication “AIL” is output
to indicate the activated state.
Test Mode 1
Single alternating pulses are transmitted to the S/T-interface resulting in a frequency of
the fundamental mode of 2 kHz.
Test Mode 2
Continuous alternating pulses are transmitted to the S/T-interface resulting in a
frequency of the fundamental mode of 96 kHz.
Reset
A hardware reset, the C/I command RES or setting the RES_TR bit in the SRES register
to ’1’ forces the SCOUT to an idle state where info 0 is transmitted. Thus activation from
the NT is not possible.
